4. Finally, you obtain:
Answer: width is 12, length is 16
Step-by-step explanation:
A= l*w
l=w+4
A=w(w+4)
factor
(w+16)(w-12)
w= -16 or w=12
width is 12, length is 16
Answer:
B. Vertical Compression
Step-by-step explanation:
<em>You've answered the question; However, I'll assist with the explanation;</em>
Given
Original:
Translated:
Required
Determine the type of transformation applied to the original function
Observing both functions, we notice that is a common factor;
This implies that the function was compressed or stretched along the y axis (vertically)
To determine if its vertical compression or stretch;
We have to divide the translated function by the original function;
<em>Because 0.125 < 1, then the transformation is a vertical compression</em>
