They have different masses
Answer:
Her mistake is that she should plot the point (0, 5) first, not (1, -3)
Step-by-step explanation:
First I simplified the equation given.
y - 3 = 2 (x + 1)
y - 3 = 2x + 2
+3 +3
y = 2x + 5
Since 5 is our y-intercept we would want to graph that first, which would be (0, 5) as a point.
Hope this helps!
Answer:
D.) 4
Step-by-step explanation:
Here,
1.25(4x-10)=7.5
5x-12.5=7.5
5x=7.5+12.5
x=20/5
x=4
we have that

we know that
Triangles ABC and A'B'C' are similar
Step 
Find the distance AB and distance A'B' with the formula

a) distance AB



b) distance A'B'




Step 
Find the scale factor

therefore
the answer is
the scale factor of the dilation is equal to
