Answer:
42ft²
A = 6ft X 5ft = 30ft²
B = 4ft X 6ft ÷ 2 = 12ft²
30ft² + 12ft² = 42ft²
Wouldnt you need it to equal something? like a-5=b so then b+5=a
Answer:
Explanation:
slope intercept form: y = mx + b
where m is slope and b is y-intercept.
The easiest way to find the inverse of a function is to swap the x and y, meaning:
We have the function
. Let's call our outputs "y", so we have
. To find the inverse, we're going to change the x and the y's position in the equation, so we have
. Then all we need to do is solve for y:
