Solve f(x) = 2x + 2 what would f(x)=20

a. 20
b. 10
c. 9
d. 8​

Answers

Answer 1

Answer:

the answer is c. 9

Step-by-step explanation:

20=2x+2

18=2x

x=9

Answer 2

Answer:

C

Step-by-step explanation:

Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is

2x + 2 = 20 ( subtract 2 from both sides )

2x = 18 ( divide both sides by 2 )

x = 9 → C

A house that costs $125,400 appreciates at a rate of 3% each year. What is the value of the
home after 3 years.
a.$137027.97
b.$275503.80
c.$114449.19
d.$3385800

Answers

Answer:

The value after three years is $137,027.97

Step-by-step explanation:

Here, we want to get the value of the home after 3 years

Generally, we have the exponential formula as follows;

y = P(1 + r)^t

where P is the original cost which is $124,400

r is the rate of increase which is 3% = 3/100 = 0.03

t is the time which is 3 years

Substituting these values;

y = 125400(1 + 0.03)^3 = $137,027.97

Jamie is twice as old as Natalie now. Give years ago the sum of their ages was 26. How old is each person now?

Answers

answer:

8. 67 and 17. 36

step-by-step explanation:

hi there!

to find out the age of both girls, i believe that we should divide the number 26 by 3 because jamie is twice as old as natalie meaning ( natalie ) is younger

26/3

= 8. 67

meaning 8.67 is how old natalie is/was

add 8.68 to itself once and you will get jamie's age!

8. 67 + 8. 67

= 17. 34

meaning 17. 34 is how old jamie is/was
