Presuming the circle is the whole, 1/4 + 1/2 is 3/4, or 0.75, so it is 75% of the circle.
Answer
The answer is A, y=-1/2x +2
Answer:
The first mechanic charges $105 per hour, and the second mechanic charges $90 per hour.
Step-by-step explanation:
If x is the rate of the first mechanic, and y is the rate of the second mechanic, then:
10x + 5y = 1500
x + y = 195
Solve the system of equations using elimination or substitution. Using substitution:
10x + 5 (195 − x) = 1500
10x + 975 − 5x = 1500
5x = 525
x = 105
y = 195 − x
y = 90
The first mechanic charges $105 per hour, and the second mechanic charges $90 per hour.
Answer:
a
Step-by-step explanation:
g(x)=-x²
f(x)=|x+2|
f(3)=|3+2|=5
(g*f)(3)=g(f(3))=g(5)=-5²=-25
Number 2 is 5-4 (1) number 4 will just be 2-2 (0)
