Answer:
f^-1(x)=100-x
Step-by-step explanation:
The exact form will be 3/2 (if you reduce, how many times will one go into three? three times, two will go into 4 twice so that is one way to get the answer.) Decimal form is 1.5 and the mixed number form will be one and one half (or 1 1/2)
Remember, rise/run is the easiest way to determine slope
y=mx+b is form
mx is slope, whilst b is y int
so, answer? y=-3x-2
Or A.
Supplementary = 180 degrees...
A + B = 180
3x + 12 + 7x + 38 = 180
10x + 50 = 180
10 x = 130
x = 13
To find the A just substitute x in...
3 ( 13) + 12
A = 51
To check substitute the x..
A + B = 180
3(13) + 12 + 7(13) + 38 = 180
51 + 129 = 180
180 = 180
Answer:
triangle with two equal sides.The angles opposite the equal sides are also equal.
