A) 2y = f(x) ⇒ y = f(x) → This is a vertical shrink by a factor of
B) y = f(2x) → This is a horizontal shrink by a factor of
The formula is 1/2bh so 1/2 ×19×9.7 =85.5 square yds.
Answer:
L=8
Step-by-step explanation:
area of a rectangle = length x width
given:
area= 20 square units
width =2.5 units
find the length by substituting :
20=2.5 x L
L= 20/2.5=8
that's it :)
Answer:
x²+8x+16
Step-by-step explanation:
f(x) = (x+4)²
= (x+4)(x+4)
= x² + 4x + 4x + 16
= x² + 8x + 16
Answer:
-1.7
Step-by-step explanation:
8.7 + X =7
incorporate the shoes and socks method. We must do the opposite of what is being done. If we are adding X, we will subtract X on both sides leaving you with 8.7=7-x. We want X on one side of the equation so now we take the 8.7 and subtract on both sides giving 7-x-8.7. we must add X on both sides so we can have a X on one side thus X= 7-8.7. we can ordinary subtract and will give us -1.7.
X=-1.7
8.7+(-1.7) =7
