Answer:
I think B 82.3%
Step-by-step explanation:
x = 5i x =-5i
Step-by-step explanation:
x^2+25=0
Rewriting
x^2 - (-25)=0
Writing as the difference of squares
a^2 - b^2= (a-b) (a+b)
where a = x and b = (sqrt(-25)) =±5i
( x-5i) ( x+5i) =0
Using the zero product property
x-5i =0 x+5i =0
x = 5i x =-5i
Answer:
It would be any positive slope.
Answer:
y=8.50x
Where y is the total cost and x is the number of cars washed
Step-by-step explanation:
Divide 93.50 by 11 and you get 8.50. When you divide 195.50 by 23, you still get 8.50. Therefore, the cost of the car wash is 8.50 per car.
