Answer:
slope is 2
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y2-y1}{x2-x1}[/tex]
= [tex]\frac{-4-6}{-2-3}[/tex]
= [tex]\frac{-10}{-5}[/tex]
= [tex]2[/tex]
What is the slope of the line that passes through the points (0,7) and (-4,3)
Answer:
The slope=1
Step-by-step explanation:
(0,7)=(x,y) and (-4,3)=(`x,`y)
The formula for finding slope= `y - y/`x - x
3-7/-4-0
-4/-4

Directed line segment PT has endpoints whose
coordinates are P(-2, 1) and 1(4,7). Determine
the coordinates of pointſ that divides the segment
in the ratio 2 to 1.
Answer:
(2 , 5)
Step-by-step explanation:
point (x,y) that divides the segment PI in the ratio 2 to 1
PD=4 - (-2) = 6 PE/ED=2/1 PE=2ED PE+ED=6 3ED=6 ED=2 PE=4
coordinate of E (2,1) .... 2 is x coordinate of E
DI=7-1=6 DF/FI=2/1 DF=4
coordinate of F (4,5) .... .... 5 is y coordinate of E
CF // PD PC/CI=DF/FI=2/1
C (2,5)
Coordinates of the point intersecting segment PT in the ratio of 2 : 1 will be (2, 5).
Given in the question,
Segment PT with endpoints P(-2, 1) and T(4, 7).Point (h, k) divides the segment in the ratio of 2 : 1.If the endpoints of a segment PQ have been given as[tex]P(x_1,y_1)[/tex] and [tex]Q(x_2,y_2)[/tex] and a point [tex](h,k)[/tex] divides this segment in the ratio of m : n,
[tex]h=\frac{mx_2+nx_1}{m+n}[/tex]
[tex]k=\frac{my_2+ny_1}{m+n}[/tex]
If the extreme ends of a segment PT are [tex]P(-2,1)[/tex] and [tex]T(4,7)[/tex] and a point (h, k) divides this segment in ratio of 2 : 1,
[tex]h=\frac{2(4)+1(-2)}{2+1}[/tex]
[tex]h=2[/tex]
[tex]k=\frac{2(7)+1(1)}{2+1}[/tex]
[tex]k=5[/tex]
Therefore, coordinates of the point intersecting segment PT in the ratio of 2 : 1 will be (2, 5).

Find 18.5% of 500- I couldn’t seem to figure this one out for some reason I dunno
Answer:
92.5
Step-by-step explanation:
18.5
[tex] \frac{18.5}{100} \times 500 \\ \\ [/tex]
100 times 5 is 500
so 100 is cancelled and 500 becomes 5
therefore 18.5 times 5 is equal to 92.5
Answer:
92 1/2 or 92.5
Step-by-step explanation:
how to solve?
Put it into a percent proportion :D!
Percent proportion is is/of=%/100 or a/w=p/100
The a stands for "part"
and the w stands for "whole"
p stands for "percent"
Is/of=%/100 will help you figure it out if it's in a mathmatical sentence.
Since they did NOT give you what the "is" is, you put the variable "a"
a/ =
Next,
Since it said "of"
You put of underneath the unknown number "is" (a)
a/500=
Now put in the percent
a/500=18.5/100
Now cross multiply!
Then you should get 92.5!

April, May and June have
90
sweets between them. May has three-quarters of the number of sweets that June has.
April has two-thirds of the number of sweets that May has. How many sweets does June have?
Answer:
40 sweets
Step-by-step explanation:
Let june have x sweets
may has 3x/4 sweets
April has x/2 sweets
total sweets is 90
Adding all sweets =
x/2+3x/4+x = 90
9x = 360
x = 40
Therefore June has 40 Sweets
Can a set of data have more than one line of best fit? Why or why not?
Line of best fit refers to a line through a scatter plot of data points that best expresses the relationship between those points. Statisticians typically use the least squares method to arrive at the geometric equation for the line, either though manual calculations or regression analysis software. A straight line will result from a simple linear regression analysis of two or more independent variables. A regression involving multiple related variables can produce a curved line in some cases.

Calculate the perimeter of ABCD.

6 cm
950
8 cm
5 cm
C
Answer:
The perimeter is 28.13 cm
Step-by-step explanation:
We connect a line from A to C
we can use the cosine rule to find the length AC
let us call it x
AC^2 = AB^2 + BC^2 - 2(AB)(BC) cos B
we have this as;
x^2 = 6^2 + 8^2 - 2(6)(8) cos 95
x^2 = 36 + 64 + 8.37
x^2 = 108.37
x = √108.37
x = 10.4 cm
AC = 10.4 cm
now, let us look at triangle ADC Where we have AC as the hypotenuse as it is the side facing the right angle
We can use Pythagoras’ theorem to get the value of CD
We have it that the square of the hypotenuse AC is the sum of the squares of the two other sides
let DC be y
10.4^2 = 5^2 + y^2
y^2 = 108.37 - 25
y^2 = 83.37
y = √83.37
y = 9.13 cm
The perimeter of the shape is the sum of all its sides
so we have;
AB + BC + CD + AD
= 6 + 8 + 9.13 + 5
= 28.13 cm

2. If you buy a new mint-condition action figure, worth $106 and
your baby brother bent the packaging which reduced the value
by 22%, what is the new value of your figure?
Answer:
$82.68
Step-by-step explanation:
Original price of mint - $106
Percent discount = 22%
Discount price = 22/100 * 106
Discount price = 0.22 * 106
Discount price = $23.32
New value = Original price - discount price
New value = 106 - 23.32
New value = 82.68
Hence the new value of the figure will be $82.68

6z-7>8z+2? = z < -9/2
Step-by-step explanation:
6*z-7-(8*z+2)>0
-2z - 9 = -1 • (2z + 9
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
2z+9 < 0
Divide both sides by 2
z+(9/2) < 0
Subtract 9/2 from both sides
z < -9/2
Answer: z < -9/2

Lucas has a jar of coins that contains only nickels and dimes. He has 30 coins itſ the jar worth a
total of $2.10. Which system of equations could be used to find the number of nickels, n, and
the number of dimes, d, that Lucas has in the jar?
А
n+d = 2.10
5n+100 = 30
B
n+d = 30
5n-10d =2.10
с
n-d = 30
0.05n+0.10d = 2.10
D
n-d=2.10
0.050+ 0.100 = 30
Answer:
Step-by-step explanation:
The correct system of equations which is the number of nickels and dimes that Lucas has in the jar is:
n + d = 30
0.05n + 0.10d = 2.10
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Lucas has a jar of coins that only contains nickels and dimes. He has 30 pennies in the jar, which is worth $2.10.
Let represents the number of nickels, n,
And the number of dimes, d, that Lucas has in the jar
The system of equations to find the number of nickels and dimes that Lucas has in the jar is:
n + d = 30
0.05n + 0.10d = 2.10
This system can be used to solve for the values of n and d. The first equation represents the total number of coins, and the second equation represents the total value of the coins in the jar.
