Answer:
x = -4 y = -5
Step-by-step explanation:
2x + 3 = -x - 9
3x + 3 = -9
3x = -12
x = -4
y = - (-4) - 9
y = 4 - 9
y = -5
Answer:
Step-by-step explanation:
The ratio of its areas is equal to
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
In this problem the scale factor is equal to the ratio 10:3
Let
z-------> the scale factor
so
z2=(10/3)2=100/9
Plug all the point into your calculator. Not sure if you need it y=mx+b but the R for that is r= -1
Answer:
y=1/2x-3
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-7-(-1))/(-8-4)
m=(-7+1)/-12
m=-6/-12
m=1/2
y-y1=m(x-x1)
y-(-1)=1/2(x-4)
y+1=1/2x-4/2
y=1/2x-2-1
y=1/2x-3
