Answer:
angle ZXY= 5x+8 = 5(13)+8 =73
angle ZXW= 7x-4= 7(13)-4=91-4=87 degrees
it is a
Step-by-step explanation:
add two angles together = 160
5x+8+7x-4=160
12x+4=160
12 x =160-4
x=156/12= 13
angle ZXY= 5x+8 = 5(13)+8 =73
angle ZXW= 7x-4= 7(13)-4=91-4=87 degrees
Answer:
scale factor = 3
Step-by-step explanation:
To determine the scale factor, calculate the ratio of the image x and y coordinates to the original x and y coordinates, that is
scale factor = 
= 
= 3
Answer:
1. y=5 and x=-5
2. y=2 and x=-4
Step-by-step explanation:
1.y=-5x-19
y=-6x-24
since both equations are equal to y, they are also equal to eachother
-5x-19=-6x-24
addition P.O.E.
x-19=-24
addition P.O.E.
x=-5
substitute x into one equation
y=-5*-5-19
y=6
2. y=-6x-22
y=-3x-10
since both equations are equal to y, they are also equal to eachother
-6x-22=-3x-10
addition P.O.E.
-22=3x-10
addition P.O.E.
-12=3x
division P.O.E.
-4=x
substitute x into one equation
y=-3*-4-10
y=2
The answer is in the picture
