I believe the answer is D
Answer:
Step-by-step explanation:
a+b=191
a-b=63
i sum these
a+b+a-b=191+63
2a=254
a=254/2
a=127
b=191-127
b=64
2:3 3 possible options (quarter+dime= 35, quarter+nickel=30, dime+nickel=15) two options are more than 20
G(x) = 2x + 1
<u>Find g(a + h):</u>
g(a + h) = 2(a + h) + 1 = 2a + 2h + 1
<u>Find g(a):</u>
g(a) = 2(a) + 1 = 2a + 1
<u>Find g(a + h) - g(a):</u>
g(a + h) - g(a) = 2a + 2h + 1 - ( 2a + 1)
Distribute the negative sign:
g(a + h) - g(a) = 2a + 2h + 1 - 2a - 1
Combine like terms:
g(a + h) - g(a) = 2h
Answer: 2h
8x + 6 < -58
Subtract 6
8x < -64
Divide 8
x < - -8
All values below -8 is highlighted, with a non-filled circle at -8
-5x - 2 ≤ 28
Add 2
-5x ≤ 30
Divide -5
x

-6
x must be greater than or equal to 6, so fill in point "6" and create a line moving rightward from there.
-5x ≤ 30
Divide -5
x
