#2 - yes, no, yes, no
#4 - exponential
#5 - (y = 2x + 3) is linear, (y = 2x^3) is not linear, (y = 3x^2) is not linear, and (y = -x - 1) is linear
#6 - the last option
#7 - true, false, true, false
Answer:
The answers are options A and B
First solve the inequality
7x < 21
Divide both sides by 7
That's
7x/7 < 21/7
x < 3
The values that satisfy the inequality are
1 and 2 since they are both less than 3
Hope this helps you.
