Area = length x width
When you multiply fractions, multiply top number by top number and bottom number by bottom number:
9/10 x 2/3 = (9 x 2) / (10 x 3) = 18/30 this can be reduced by dividing both numbers by 6:
18/30 reduces to 3/5
Answer: 3/5 square feet
Answer:

Answers:
Graph A is a function
Graph B is not a function
========================================================
Explanation:
To check if we have function or not, we apply the vertical line test. This test is where you ask yourself: "Is it possible to draw a single vertical line through more than one point on the curve?"
If the answer to that question is "yes it is possible", then we do not have a function. Graph B shows that we can draw a line through say x = 2 and have the vertical line intersect at points (2,2) and (2,4). The input x = 2 leads to multiple outputs y = 2 and y = 4 simultaneously. This is why graph B is not a function.
A function is only possible when any x input from the domain leads to exactly one y output in the range. Graph A is a function because we cannot draw a single vertical line to intersect through that curve more than once.
Answer:
f^-1(x) = (4x +3)/(1 -x)
Step-by-step explanation:
Solve for y:
f(y) = x
(y -3)/(y +4) = x
y -3 = xy +4x . . . . . . multiply by y+4
y -xy = 4x +3 . . . . . . add 3-xy
y(1 -x) = 4x +3 . . . . . factor out y
y = (4x +3)/(1 -x) . . . divide by the coefficient of y
The inverse function is ...
f^-1(x) = (4x +3)/(1 -x)
