Answer:
A, D , and E
Step-by-step explanation:
We have that:


is the image of CD after a dilation of scale factor n.
We use the relation between the image length and object length:

Option A
If n=3/2, then

This is true.
Option B
If n=4, then

This is false.
Option C
If n=8, then

This too is false.
Option D
If n=2, then

This is true
Option E
If n=3/4, then


This is also true.
Answer:
b
Step-by-step explanation:
Answer:
Moderate
Step-by-step explanation:
I think sorry if its wrong
The value of b is -16 and the value of ac is 60 after comparing with the standard equation.
<h3>What is a quadratic equation?</h3>
Any equation of the form
where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:

We have a quadratic function:
= 3x² - 16x + 20
On comparing with standard function:
b = -16
a = 3
c = 20
ac = 3(20) = 60
Thus, the value of b is -16 and the value of ac is 60 after comparing with the standard equation.
