Math question 40 points!

1. the sum of 5 consecutive odd integers is 2,555. what is the sum of the first, third, and last integer?

2. find the solution to the following system of linear equations.

y = −9x + 20
y = −9x +16

3. how many solutions exist for the system of equations given below?

3a + 4b = 20
12a = 80 − 16b

4. determine the value of x for the following system of equations.

3x + 4y = 70
8x - 3y = 9

answer:

i think 900 is three   and the first is like 100

for two just divide 9/9 9/20 2/9 9/16

i think three

8=i beleive 25

step-by-step explanation:

11 feet 6 inches and 8 feet 6 inches

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
