So it's part of a diameter with the 40, so you should have taken 180-40=140 then it should have been set equal to 140. So 22x+8=140 then 22x=132 then 132÷22=6 so x=6
First, find g(2): g(2)=2*2-7=-3
next, find f(-3): f(-3)=2(-3)+1=-5
so the answer is -5.
Step-by-step explanation:
To subtract, you must first:
Find like denominators.
- Note: What you do to the denominator, you must do to the numerator.
- If there is an equal sign, and there are fractions on both side, what you do to one side, you do to the other.
Simplify:
-----------------------------------------------------------------------------------------
Take for example, a question such as:
7 3/10 - 9/20
First, change the mixed fraction into improper fraction:
7 = (7/1) * (10/10) = 70/10 + 3/10 = 73/10
Find common denominators. Remember that what you do to the denominator, you do to the numerator. Multiply 2 to both numerator and denominator:
(73/10)(2/2) = (146/20)
Simplify. Combine like terms
146/20 - 9/20 = 137/20
Simplify.
137/20 = 6 17/20
6 17/20 would be your answer for the example question.

Answer:
23
Step-by-step explanation:
Using an online calculator and plugging the values in, we get our equation of y=mx + b to become y = 1.2x - 17.8 .
Plugging 34 in for x, we get 1.2(34) - 17.8 = 23 for their projected test grade
