F(x) = -7x - 1
f() = -8

Answers

Answer:

  f(1) = -8

Step-by-step explanation:

Apparently, you want the argument of the function such that the function value is -8. Fill in the given information and solve for x:

  -8 = -7x -1

  -7 = -7x . . . . add 1

  1 = x . . . . . . . divide by -7

Now, you know that ...

  f(1) = -8

For what values of x is x2 + 2x = 24 true?–6 and –4
–4 and 6
4 and –6
6 and 4

Answers

you can solve this 2 ways: plug in all of the options or solve for x.
i going to solve for x.

given: x^2+2x=24     (subtract 24 on both sides to get make it look like x^2+x+1)

x^2+2x-24=0    (now factor x^2+2x-24 out)

x^2+2x-24 --> (x-4)(x+6)

new equation: (x-4)(x+6)=0   (now make them both equl zero)

new equaions:    x-4=0      x+6=0     (now solve for x for both)

x-4=0        x+6=0
   x=4            x=-6
your answer is 4 and -6.
if you were not taught how to do what i just did then i can message you how to plug those numbers into  x^2+2x=24 to find the answer.

Explain how you can tell that 31/33 is in simplest form

Answers

The simplified form of the fraction 31/33 is 31/33.

What is fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

A fraction,

31/33.

A fraction that can not be factorized further is the simplest form of the fraction.

31 and 33 both numbers do not have a common divisor other than 1.

Therefore, 31/33 is in the simplest form.

I NEED HELP ASAP (A new pizza shop opened up and started out$5,344.46 in the hole. Their first month being open they sold 61 pizzas ($3.06 profit each) and 89 sodas ($1.42 profit each). Thier bills for the first month were $1,208.01. How much money do they still need to make to break even?

Answers

Answer:

$894.97 is needed more to break even

Step-by-step explanation:

In this question, we want to know how much money the pizza shop need so that their profits will equal their expenses.

Let’s calculate their profit

This can be calculated from the pizza sales

That would be;

61(3.06) + 89(1.42) = $186.66 + $126.38 = $313.04

Now, given that their bills for the first month is $1,208.01, the amount still needed to break even would be the amount of their bills minus the profit made from selling soda and pizza

That would be 1,208.01 - 313.04 = $894.97

This set of points is on the graph of a function.{(−3, 9), (−1, 1), (0, 0), (2, 4)}

Which points are on the graph of the inverse?

Select each correct answer.

Answers

Answer: (9, -3), (1, -1), (0, 0), and (4, 2)

Step-by-step explanation:

Inverse is when the x's and y's are swapped:

The given points are: {(-3, 9), (-1, 1), (0, 0), (2, 4)}

The inverse points are: {(9, -3), (1, -1), (0, 0), (4, 2)}

Answer:

(9, -3), (1, -1), (0, 0) and (4, 2)

Step-by-step explanation:

The definition of an inverse of a function is "the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function."

This means too find the inverse of a function using ordered pairs, switch the x- and y-coordinates.

This means that (-3, 9) goes to (9, -3); (-1, 1) goes to (1, -1); (0, 0) goes to (0, 0); and (2, 4) goes to (4, 2).
