Answer:
Area = length * width
112 = (2w+2)*w
112 = 2w^2 + 2w
0 =2w^2 + 2w - 112
0 = w^2 + w - 56
0 = ( w + 8 )( w - 7 )
w+8=0 results in negative measures
w-7=0 --> w = 7
width is 7
length is 16
First, since the building is 5.5 inches and the scale is 1 inch for 8 feet, you would multiply 5.5* 8 to get 44 feet.
Y varies inversely with x
means that y=k/x
with x=0.7 and y=80
we have 80=k/0.7
k=0.7x80=56
so the equation is
y=56/x
Answer:
d 64
Step-by-step explanation:
f(-3)=1/2 ^-6=2^6=64
3x-2 if x is less an or greater than 1, will be a negative y value.
-2x+3 when x is greater than 1 will also be a negative y value.
The graph would be the first one ( an upside down V)
