Answer:
scale factor = 5
Step-by-step explanation:
To determine the scale factor calculate the ratio of corresponding sides of the enlargement to the original, that is
scale factor = = = 5
Answer:Slope is 3 y-intercept is -2
y=mx+b. m=slope b is y-intercept
y=3x-2
Comparing both equations we find out that slope is 3 and y-intercept is -2

$60= 400 ×.05 × t
$60= 20× t
t= 60/20
