The answer is C

I’m 100% sure

Explanation:
If 3 is 56.5, then 4 would be:
180-56.5= 123.5

Since 3 and 4 are parallel to 7 and 8, they have the same angle sizes.

Therefore, angle 8 has the same answer as angle 4, which is 123.5. Answer is C.

1. For the function rule y = -2x - 3, provide the x-y coordinates of the y-intercept and the x-intercept. Show your work.

Mars2501 [29]

The function is y=f(x)=-2x-3

the graph of this function are all pairs (x, y)=(x, f(x))=(x, -2x-3)

the y-intercept of a graph of a function, is the point where the graph cuts the y-axis, which happens at x=0.

at x=0, f(x)=f(0)=-2*0-3=-3

the x-intercept(s) of the graph, are the point(s) where the graph intersects the x-axis. At those points, the y-coordinate is 0.

so the x-intercept(s) are points of the form (x, 0)

now,

(x, 0)=(x, -2x-3)

0=-2x-3
2x=-3
x=-3/2

Answer:

x-intercept: (-3/2, 0)
y-intercept: (0, )

If George is 33 1/3% richer than Pete, than Pete is what percent poorer than George?

OleMash [197]

Answer:

25%

Step-by-step explanation:

George is 33 $\frac{1}{3}$ % ( $\frac{100}{3}$ %) richer than Pete. Let Pete's percentage of wealth be 100%.

Thus George percentage of wealth = 100% + $\frac{100}{3}$ %

= $\frac{400}{3}$ %

= 133 $\frac{1}{3}$ %

Pete's percent poorer than George can be determined by;

= $(\frac{100}{3})$ ÷ $(\frac{400}{3} )$ × 100

= $(\frac{100}{3})$ × $\frac{3}{400}$ ×100

= 0.25 × 100

= 25%

Pete is 25% poorer than George.

Question 1: On a coordinate plane, triangle ABC has vertices at A(10,5), B(10,15), and C(5,5). Triangle A'B'C' has vertices at A

Vilka [71]

Answer:

B. (x,y) --> (4x - 10, 4y - 8)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, dilation and rotation.

If a point X(x, y) is translated a units right and b units up, the new location is (x + a, y + b) also If a point X(x, y) is translated a units left and b units down, the new location is (x - a, y - b)

If a point X(x, y) is dilated by the factor k the new location is X'(kx, ky).

Triangle ABC has vertices at A(10,5), B(10,15), and C(5,5), If it is dilated by a factor of 4, the new location is A*(40, 20), B*(40, 60) and C*(20, 20). If then a translation of 10 units left and 8 units down, the new points are A'(30, 12), B'(30, 52), C'(10, 12).

This is a transformation of (x,y) --> (4x - 10, 4y - 8)
