An auto repair shop charged $75/h for labor plus an additional $89 for parts. If the shop worked for 2 h, which equation represents the total repair cost C ?A. C = 75(2) − 89
B. C = 89(2) + 75
C. C = 75 + 89
D. C = 75(2) + 89

Answers

Answer:

The total cost for the repair is represented by C = 75 (2) + 89 .

Option (D) is correct .

Step-by-step explanation:

As given

An auto repair shop charged $75/h for labor plus an additional $89 for parts.

If the shop worked for 2 h.

C = Represented the total repair cost .

Than the equation becomes

C = 75 × 2 + 89

C = 75 (2) + 89

Therefore the total cost for the repair is represented by C = 75 (2) + 89 .

Option (D) is correct .

d. C= 75(2)+89 because you multiply the amount of hours by the cost per hour then add the cost of parts

The solution to the given quadratic equation buy factoring is: x = -7 or 7

How to solve quadratic equations?

A quadratic equation is an equation of degree 2 and has the standard form: ax² + bx + c = 0, with a ≠ 0

We can solve quadratic equations by:

- Completing the square

- Quadratic formula

- Factoring

We are given the quadratic equation as:

x² - 49 = 0

Factoring this gives us:

(x + 7)(x - 7) = 0

Thus:

x - 7 = 0 or x + 7 = 0

x = -7 or 7

Divide 7/15 by 3/5.
A. 75/21
B. 7/9
C. 7/25
D. 21/75

Answers

In this question there is nothing complicated. Only thing is to know the way fractions can be divided. Once that is known the problem would be one of the easiest to solve. Now let us get back to the problem and look at all the information's that are given in the question.
Divide 7/15 by 3/5 = (7/15)/(3/5)
      = (7 * 5)/(15 * 3)
   = (35/45)
Dividing the numerator and the denominator by 5 for simplifying purpose, we get
   = 7/9
So from the above deduction we can easily conclude that 7/9 is the correct answer and option "B" is the correct option among all the options given in the question.

If you would like to solve 7/15 / 3/5, you can calculate this using the following steps:

7/15 / 3/5 = 7/15 * 5/3 = 7/9

The correct result would be B. 7/9.

What is the end behavior of the graph of the polynomial function f(x) = –x^5 + 9x^4 – 18x^3?

Answers

Answer: its C

Step-by-step explanation:

hello

For example, the monomial y = x 2 has the following end behavior: y → ∞ as x → −∞ and y → ∞ as x → ∞
For any polynomial, the end behavior is determined by the term that contains the highest power of x, because when x is large, the other terms are relatively insignificant in size.
