Answer:
y-3 = -2/9(x+1)
Step-by-step explanation:
Here, we want to find the standard equation
Generally, we have the equation as;
y = mx + b
where m is the slope of the line and b is the y intercept
To find the slope, we use the slope equation
m =y2-y1/x2-x1
m = (3-1)/(-1-8) = 2/-9 = -2/9
So to write in point slope form, we can use any of the two points
We have;
y-y1 = m(x-x1)
using (-1,3)
y-3 = -2/9(x+1)
Parallel Lines
PLEASE HELP I NEED ASAP!
Answer:
B
Step-by-step explanation:
The triangles do have equal angles and proportional sides, because they are bot right triangles formed on parallel lines.
:)ur welcome
Answer: Choice B
Yes. Right triangles formed on parallel lines have proportional side lengths and congruent angles.
====================================================
Explanation:
Parallel lines always have equal slopes, but different y intercepts.
Recall that slope = rise/run.
The "rise" is the vertical portion of the triangle, while the "run" is the horizontal portion.
So let's say we had a slope of rise/run = 2/3. This means rise = 2 and run = 3.
If we had something like rise/run = 4/6, then that reduces to 2/3, showing that 4/6 = 2/3. They are the same slope.
We can use the SAS similarity theorem to prove the triangles formed in the diagram are congruent based on what is discussed above.
Because the triangles are similar, this means the corresponding angles are congruent. One such pair is the pair of right angles shown.

To draw the designs for sizes 3, 4, and 5 of Johnny's newly designed tile, we need to follow the same pattern as sizes 1 and 2.
Size 3 has a 7x7 grid of tiles with nine white tiles in the center and 16 black tiles around them,
Size 4 has a 9x9 grid of tiles with 16 white tiles in the center and 20 black tiles around them.

Step-by-step explanation:
(diagram with colors below)
The two red sides can be visualized as the same length as the length, so the two red segments add up to 18cm. The same thing can be said with the blue segments and the width. We can say the perimeter can be:

Josiah invests $360 into an account that accrues 3% interest annually. Assuming no deposits or withdrawals are made, which equation represents the amount of money in josiahs account, y, after x years?
a-y=360(1.3)^x
b-y=360(0.3^x
c-y=360(0.03)^x
d-y=360(1.03)^x
Answer:
y = 360 (1.03)^x
Step-by-step explanation:
Amount in account = principle * (1+ rate) ^ time
When the interest is annual
rate is in decimal form and time is in years
y = 360 ( 1+.03) ^x
y = 360 (1.03)^x

Answer: 24, b
Step-by-step explanation:
So it said "In the Math Club", 67% are not in the literature club. We also know that this 67% is 16 people.
Now we can set up an equation to find the total number of people in the math club. Let's say the total number of people in the Math club is x, so 0.67x = 17, and x = 25.37 rounded. So if 25 people in total, 16 not in the literature club, then that means 25-16 = 9 people are in both the Math club and the Literature club.
So of the students "Not in the Math Club", it said that 78 percent are not in the Literature Club. This means 22 percent are in the literature club. We also know 4 people are in the literature club.
Now we can set up an equation to find the total number of people not in the math club. Let's say the total number of people not in the Math club is x, so 0.22x = 4, x = 18.18 rounded. So if 18 in total, 4 in the literature club, than 14 not in the literature club.
Since x = 9, and y = 14, x+y will equal 23, rounding up to 24 since we rounded down the total number of people.

A sports teacher had 1025 sweets. After distributing these equally amongst all the participants in a sports meet, he had just 1 sweet left with him. Which of these could be the number of sweets given away to each participant?
Answer:
C. 8
Step-by-step explanation:
Options
A. 5
B. 6
C. 8
D. Can't say without knowing the number of participants
Number of sweet distributed = Total number of sweets - left over sweets
= 1025 sweets - 1 left over sweet
= 1024 sweets
Number of participants = Number of sweets distributed / number of sweets given to each participant
A. 5
Number of participants = Number of sweets distributed / number of sweets given to each participant
= 1024 /5 Sweets
= 204.8 participant
B. 6
Number of participants = Number of sweets distributed / number of sweets given to each participant
= 1024/6
= 170.67 participant
C. 8
Number of participants = Number of sweets distributed / number of sweets given to each participant
= 1,024/8
= 128 participant
D. Can't say without knowing the number of participants
From the options given, the number of sweets given away to each participant could be 8
Number of sweets given to each participants is 32.
Since, A sports teacher had 1025 sweets and he had one sweet left after distributing.
So, number of sweets he distributing is, [tex]1025-1=1024[/tex]
Since, distributing these equally amongst all the participants
Therefore, number of sweets given to each participants is, [tex]=\sqrt{1024}=32[/tex]
So, total number of participants is 32 and number of sweets given to each participants is 32.

Given:
The parent function is:
[tex]f(x)=x^2[/tex]
The graphs of f(x) and g(x) are given.
The graph of g(x) passes through the point (3,3).
To find:
The function g(x).
Solution:
From the given graph, it is clear that the graph of f(x) compressed vertically to get the graph of g(x). So,
[tex]g(x)=kf(x)[/tex]
Where, k is the stretch factor.
It can be written as:

The graph of g(x) passes through the point (3,3). Putting [tex]g(x)=3,x=3[/tex] in (i), we get

Putting [tex]k=\dfrac{1}{3}[/tex] in (i), we get

with explanation please.
Answer:
There are 5 sides in the polygon.
Total perimeter of the polygon is 12.5 cm and it is a regular polygon.
Each side of the polygon is 2.5 cm.
So total number of sides is: Total perimeter of the polygon / Length of each side = 12.5 cm/ 2.5 cm = 5
Hence, the polygon has 5 sides and it is a regular pentagon.
