<B+<D = 180
x+148 = 180
x = 32
<A = 2(32) + 1
<A = 64+1
<A = 65
The correct slope is 11/2. You can find this with the rise and run method or converting to slope intercept form which is y=11/2x+20.
To get the inverse, first off do a quick switch on the variables, and then solve for "y".
Answer:
x+2/5x
Step-by-step explanation:
x%of 40 is 2/5x
...40 increased by x% of it self = x+2/5x
