1st Problem:
the function is f(x) = -x². Here below all the values :
f(-3) = -9
f(-2) =-4
f(-1) = -1
f(0) = 0
f(1) = -1
2nd Problem: Temperature > -15
3rd Problem: Let x be the number of hours, then the equation will be:
RENT + HX$15 = $95
$35 + 15x = 95
15x=95-35
15x=60
x=60/15
x=4. Then the number of hours is 4
4th Problem:
c/4 - 5 =4==> reduce to same denominator==> (c-20)/4 = 16/4
c-20 =16 & c=36
5th Problem
Solve the inequality y-6>=12
y >=12+6
y>=18
