Use the given conditions to write an equations for the line in slope- intercept form. passing through (1,-8) and (-7,8)
Answer:
y = -2x - 6
Step-by-step explanation:
Going from the first point to the second, we see x decreasing by 8 from 1 to -7 (this is the 'run') and y increasing by 16 from -8 to +8 (this is the 'rise'). Thus, the slope of the line through these two points is m = rise/run = 16/(-8) = -2.
Using the point-slope formula y - k = m(x - h) and the point (1, -8), we get:
y + 8 = -2(x - 1), or
y = -8 - 2x + 2, or
y = -2x - 6 (in slope-intercept form)

For problems 1 - 4, write a two-column proof.
Solution given:
1:
<5=<6
<5+<4=180°[co interior angle]
Substituting value of<5
<6+<4=180°[it shows a property of co interior angle]
So
l || m
2:
<1=90°[ l is perpendicular to t]
<2=90°[m is perpendicular to t]
since
<1=<2[shows property of corresponding angle]
:.
l || m.
3:
<1=<2
<1=<3
substituting value of<1 in second one
<2=<3[which shows property of alternate Angel]
So
Segment ST || segment UV.
4:
<RSP=<PQR......[I]
<QRS+<PQR=180°.....[ii]
from equation I and ii we get
<RSP+<QRS=180°[which shows property of co interior angle ]
So
Segment PS || segment QR
These pictures are the questions given in the pdf, let's get the solutions.
1) Solution
It is given that,
→ <5 = <6
Then the co interior angles,
→ <5 + <4 = 180°
Now substituting value of <5,
→ <6 + <4 = 180°
This shows property of co interior angle.
Therefore, L ll m
2) Solution
Take it as,
→ <1 = 90°
In above eq. L is perpendicular to t.
→ <2 = 90
In above eq. m is perpendicular to t.
Then it will be,
→ <1 = <2
It shows property of corresponding angle.
Therefore, L ll m.
3) Solution
It is given that,
→ <1 = <2 and <1 = <3
Now substitute,
The value of <1 in second one,
→ <2 = <3
This shows property of alternate angle.
Therefore, ST || UV.
4) Solution
It is given that,
→ <RSP = <PQR --- (1)
→ <QRS + <PQR = 180° --- (2)
Now from the equation (1) and (2),
→ <RSP + <QRS = 180
It shows property of co interior angle.
Therefore, PS || QR.

find the perimeter of the figure
Answer:
72cm
Step-by-step explanation:
We have 4/6 sides. 4 of them are given, and they are 13.25cm, 7.25cm, 7.75cm, and 22.75cm.
The perimeter is found when you add all the lengths of the sides of a figure.
So far, we can add 13.25+7.25+7.75+22.75 = 51cm.
Let's call the first ungiven side A. We can see that 7.75cm + A = 13.25cm. Using this, we can figure out that A = 13.25-7.75 = 5.5cm.
We can call the second ungiven side B. We see that 7.25cm + B = 22.75cm. So, B = 22.75-7.25 = 15.5cm.
Now, let's add everything together. 51cm + A + B = Perimeter. 51cm + 5.5cm + 15.5cm = 72cm.
Hope this helps! Feel free to ask any questions if this doesn't make sense. :)

Determine whether side-angle-angle (SAA) is valid means for establishing triangle congruence. In this case, you know the measure of : side, an
adjacent angle, and the angle opposite to the side. If it is valld criterion, explain why. If it is not valid, use GeoGebra to create a counterexample
demonstrating that it doesn't work and give an explanation. If you construct a counterexample, take a screenshot of your work, save it, and insert
the image in the space below.
Answer:
Basically if you know side-angle-anlge, you can determine the third angle by
3rd angle = 180 - angle 1 - angle2
In this way, you are using the Angle-Side-Angle method of congruence.
Step-by-step explanation:
Answer:
In this case SAA is a valid means for establishing triangle congruence. You can see in the following image. The triangles are the same, in other words congruent. How I figured it out was by making a random triangle (ABC) then finding the lengths and angles. From there, I picked a random side (AB) and angles (A) and (B) after I transferred the information I had and put it into a new triangle. Using this formula to determine the third angle: 3rd angle (C = 45*) = 180* - angle A (45*) - angle B (90*). From there, I looked for where line (BC) and (CA) would connect. Leaving me with two congruent triangles.

Belinda is thinking about buying a house for $179,000. The table below shows the projected value of two different houses for three years:
Number of years 1 2 3
House 1 (value in dollars) 186,160 193,606.40 201,350.66
House 2 (value in dollars) 190,000 201,000 212,000
Part A: What type of function, linear or exponential, can be used to describe the value of each of the houses after a fixed number of years? Explain your answer. (2 points)
Part B: Write one function for each house to describe the value of the house f(x), in dollars, after x years. (4 points)
Part C: Belinda wants to purchase a house that would have the greatest value in 30 years. Will there be any significant difference in the value of either house after 30 years? Explain your answer, and show the value of each house after 30 years. (4 points)
There are several types of functions, but this question is limited to just 2 types, which are the exponential function and the linear function.
House 1 has an exponential function of [tex]f(x) = 179000 * 1.04^x[/tex] while house 2 has a linear function of [tex]f(x) =11000x+179000[/tex]. House 1 will have a greater value in 30 years and the difference between the values of the two houses is significant.The given parameters can be represented as:
[tex]\begin{array}{cccc}{Years} & {1} & {2} & {3} & {House\ 1} & {186,160 } & {193,606.40 } & {201,350.66} & {House\ 2} & {190,000 } & {201,000 } & {212,000} \ \end{array}[/tex]
(a): The type of function
First, we check if the function is linear by calculating the difference between each year
House 1
[tex]d = 193606.40 - 186160 = 7446.4[/tex]
[tex]d = 201350.66 - 193606.40 = 7744.26[/tex]
The difference are not equal; hence, the function is not linear. So, we can assume that it is exponential
House 2
[tex]d = 201000 - 190000 =11000[/tex]
[tex]d = 212000 - 201000 =11000[/tex]
The difference are equal; hence, the function is linear.
(b): The function of each
House 1
An exponential function is represented as:
[tex]y = ab^x[/tex]
When [tex]x = 1;\ y =186,160[/tex]
We have:
[tex]186,160 =ab^1[/tex]
[tex]186,160 =ab[/tex] ---- (1)
When [tex]x = 2;\ y =193606.40[/tex]
We have:
[tex]193606.40 =ab^2[/tex] --- (2)
Divide (2) by 1
[tex]\frac{193606.40}{186160} =\frac{ab^2}{ab}[/tex]
[tex]1.04 = b[/tex]
[tex]b = 1.04[/tex]
Make a the subject in (1)
[tex]186,160 =ab[/tex]
[tex]a = \frac{186160}{b}[/tex]
[tex]a = \frac{186160}{1.04}[/tex]
[tex]a = 179000[/tex]
So, the function for house 1 is:
[tex]f(x) = 179000 * 1.04^x[/tex]
House 2
A linear function is represented as:
[tex]y = mx + b[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{201000 - 190000}{2 - 1}[/tex]
[tex]m = \frac{11000}{1}[/tex]
[tex]m = 11000[/tex]
So, the equation is:
[tex]y =m(x-x_1) + y_1[/tex]
Substitute known values
[tex]y =11000(x-1) + 190000[/tex]
[tex]y =11000x-11000 + 190000[/tex]
[tex]y =11000x+179000[/tex]
So, the function for house 2 is:
[tex]f(x) =11000x+179000[/tex]
(c): House with the greatest value in 30 years
This means that:
[tex]x = 30[/tex]
For house 1, we have:
[tex]f(x) = 179000 * 1.04^x[/tex]
[tex]f(30) = 179000 * 1.04^{30}[/tex]
[tex]f(30) = 580568.15[/tex]
For house 2, we have:
[tex]f(x) =11000x+179000[/tex]
[tex]f(30) = 11000 * 30+ 179000[/tex]
[tex]f(30) = 509000[/tex]
By comparison;
[tex]580568.15> 509000[/tex]
House 1 will have a greater value in 30 years
And the difference between the values is significant
The difference is:
[tex]d =580568.15-509000[/tex]
[tex]d =71568.15[/tex]

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal.
What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?
$60
$80
$90
$100
Answer:
80
Step-by-step explanation:
I = Prt
I = 40 R = .10 T = 5
40 = P (.10)(5)
40 = P(.5)
Divide each side by .5
40/.5 = .5P/.5
80 = P
The interest over 5 years is $80.
The correct option is B.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
The Formula to calculate the simple interest is;
S.I. = P x T x R / 100,
Where S.I. is simple interest, P is the principal amount, T is the time period and R is the interest rate in a year.
We can use the formula I = Prt to solve for P. We know that I = 40, r = 0.10, and t = 5. Substituting these values, we get:
40 = P(0.10)(5)
Simplifying:
40 = 0.5P
Dividing both sides by 0.5:
P = 80
Therefore, the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years is $80.

Answer:
Step-by-step explanation:
To evaluate such, the following must be comprehended:
Slope: Rise/Run.
X-intercept: The peculiar point in which the observed linear data intersects the x-axis.
Y-intercept: The peculiar point in which the observed linear data intersects the y-axis.
To evaluate for the slope, which is defined as the agglomerate distance between two points contained within linear data, the following equation must be utilized:
m = (y2 - y1) / (x2 - x1)
Points utilized or given: (-1, 2) and (7, 2).
2 - 2 / 7 + 1 = 0/8 ==> 0
Henceforth, the slope for the particular configuration, as provided, is understood as zero (0).
Utilizing the integral of one of the points provided, as well as slope evaluated for, the following equation could be exploited:
Point-Slope Formula:
Y- y1 = m(x - x1)
Y - 2 = 0(x - 7)
Y - 2 = 0
Y = 2
Hence, the answer to the peculiar interrogate is disclosed as 2, which is identified as where the horizontal line intersects the y-axis at (0, 2).
