If s(x)=2-x^2 and t(x)=3x, which value is equivalent to (s*t)(-7)?
andreyandreev [35.5K]

Answer:

(s*t)(-7) = 987

Step-by-step explanation:

s(x) = 2 - x²

t(x) = 3x

To find (s*t)(x), multiply s(x) and t(x).

(s*t)(x) = (2 - x²)(3x)

(s*t)(x) = 6x - 3x³

Now that you have (s*t)(x), plug -7 in.

(s*t)(-7) = 6(-7) - 3(-7)³

(s*t)(-7) = 6(-7) - 3(-343)

(s*t)(-7) = -42 + 1029

(s*t)(-7) = 987

A truck can be rented from Company A for ​$100 a day plus ​$0.20 per mile. Company B charges ​$60 a day plus ​$0.70 per mile to
denis23 [38]

Answer:

Step-by-step explanation:

First, we write the rental cost with each company:

Company A Pa = 100 + 0.2*m

Company B Pb = 60 + 0.7*m

Where m: miles travelled

Now, we need to find "number of miles in a day at which the rental costs for Company A and Company B are the same". This means Pa = Pb. Then:

100 + 0.2*m = 60 + 0.7*m

Solving the equation for m by taking 0.2m and 60 on both sides:

100 + 0.2*m - 0.2*m - 60 = 60 + 0.7*m - 0.2*m - 60

40 = 0.5*m

Finally, dividing 0.5 on both sides:

m = 80
