Answer:

Step-by-step explanation:
Given the information:
- A'B'C' reflection over x = −1
- dilation by a scale factor of 4 from the origin
<=> the two triangles are similar to each other, triangles are similar if they have the same shape, but can be different sizes, so A″B″C″ is 4 time bigger than ABC
=> the relationship between ΔABC and ΔA″B″C″
= 
We choose C.
Hope it will find you well.
Answer: 6.67 feet (check to see if you made a typo)
Step-by-step explanation:
if the scale factor is ten than we multiply 8 by 10
8 * 10 = 80
important to remember this is 80 INCHES not 80 FEET
to convert 80 inches into feet, we divide by 12 because there are 12 inches in a foot
80/12 = 6.67 feet
check to make sure that the first option is actually 6.67 inches because it would make more sense for it to be in feet
Answer:
y-9=2(x-3)
Step-by-step explanation:
The point-slope formula is: y-y1=m(x-x1)
y1 and x1 is where you plug in the coordinate and m is the slope.
y1 is the second number of the coordinate (x, y)
So, y1 is 9 in this case
x1 is the first number of the coordinate (x, y)
So x1 is 3 in this case
Do you get it or do I need to explain further?
