Answer:
C=0.75m+3
Step-by-step explanation:
3=flat fee
0.75 per mile
m=mile
c=cost
5x3 + 5x2 - 19 is the answer
Total = 7 + 12 + 6 = 25
Purple = 0
Red = 12/25
Orange = 6/25
Blue = 7/25
a. Since there is 0 purple, the answer is 0.
b. 18/25 ( 12/25 + 6/25)
c. 18/25 (Not blue = 25 - 7 = 18)
Hope this helped☺☺
Answer:
The solution set is {-3, -6}.
Step-by-step explanation:
x^2 + 18 = -9x
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
x = -3, -6.
