I'm guessing the answer is 6in.
because the original width of the photo is 8in-4in
which is 4in.
and 8 to 10 is a difference of 2
so add 2 to 4
its 6
Given : y = 8 - 9x
(a) we need to find value of y when x = 2
substituting x = 2 in y = 8 -9x , we get :
y = 8 - 9(2)
y = 8 - 18
y = -10
(b) we need to find value of y when x = 0
substituting x = 0 in y = 8 -9x , we get :
y = 8 - 9(0)
y = 8 - 0
y = 8

0 = 2 (-1) + b
0 = -2 + b
2 = b
The answer is C. 2.
This is because the part that is inside of the parentheses is equal to 4. Multiplying the fractions in the numerator is equal to 
.
, using the exponential rule 3/2-1/2=2/2 or 1. 4^1=4.
Now, we reduced the fraction, so all that is left is 
. This is equal to 2.
So your answer is 2.
I hope this helps :)
