Answer:
Step-by-step explanation:
79+80+92+92+81+100+88+98+71+100+91+90
=1,062/12 = 88.5
the answer would be b.
(f+g)(x)= 3x-2+2x+1. combine like terms: 3x+2x=5x and -2+1+-1. combine the answers to get 5x-1
Answer:
x = -4
Step-by-step explanation:
2 - (7x + 5) = 13 - 3x
add the binomial (7x +5) to both sides
2 = (7x + 5) + 13 - 3x
combine like terms
2 = 4x + 18
subtract 18 from both sides
-16 = 4x
divide by 4
x = -4
By calculating the slope, the average rate of change is -2
-1-11

1--5
Answer: About 6.2%
Step-by-step explanation:
He starts with 5500 and gains 893.75 in 2.5 years.
The equation is then 5500*(x)^2.5 = 5500+893.75, or
5500*x^2.5 = 6393.75.
x is about 1.0621, or about 6.2% because it's interest.
