7 0

Answer and Step-by-step explanation:

The answer is 2 (which is equal to x).

If you were to plug 2 in to the function, the result if 30.

x^{3}+ 6x^{2} -x\\\\\\\\(2)^3+6(2)^2 - 2 = 30 = f(2)

6 = -4x + y<br> -5x - y = 21<br> Please Help Fast!!!!!! Substitution
Vera_Pavlovna [14]

Answer:

y = 4x + 6

-5x - 4x - 6 = 21

-9x - 6 = 21

-9x = 27

x = -3

y - 4(-3) = 6

y + 12 = 6

y = -6

Amanda's family is taking a road trip. Their car can travel no more than 352 miles without needing to refill the gas tank. They
Solnce55 [7]

From the solution to the inequality, the correct interpretation is that:

Amanda's family can drive 244 miles before they need to refill the gas tank.

The amount of miles they can still travel is modeled by the following <em>inequality</em>:

108 + x \leq 352

It is solved similarly to an equality, hence:

x \leq 352 - 108

x \leq 244

Then:

Amanda's family can drive 244 miles before they need to refill the gas tank.

Select all the correct equations.
Naya [18.7K]

Answer:

You did not post the options, but i will try to answer this in a general way.

Because we have two solutions, i know that we are talking about quadratic equations, of the form of:

0 = a*x^2 + b*x + c.

There are two easy ways to see if the solutions of this equation are real or not.

1) look at the graph, if the graph touches the x-axis, then we have real solutions (if the graph does not touch the x-axis, we have complex solutions).

2) look at the determinant.

The determinant of a quadratic equation is:

D = b^2 - 4*a*c.

if D > 0, we have two real solutions.

if D = 0, we have one real solution (or two real solutions that are equal)

if D < 0, we have two complex solutions.
