Answer:

-5x + 7

Step-by-step explanation:

-4x - 2y = -2

x - 2y = 9

First, you're going to subtract the equations from each other.

(-4x - 2y = -2) - (x - 2y = 9)

Next, you need to get rid of the equal sign in both equations.

(-4x - 2y = -2) - (x - 2y = 9)

+2 +2 -9 -9

After you get rid of the equal signs, you will distribute the sign to the equation and then subtract everything.

-4x - 2y + 2 - x + 2y + 9

Now, combine the like terms.

(-4x -x) + (-2y + 2y) + (2 + 9)

Finally, calculate the terms and solve.

-5x + 7

Harman [31]

The answer to your problem would be 400 because to find the answer you need to multiply 120 by .3 to get the answer because 3 % means per 100 and that is why you make it .3 hope i help.

Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (Enter your answers as a comma-

Shtirlitz [24]

Answer:

The number c is 2.

Step-by-step explanation:

Mean Value Theorem:

If f is a continuous function in a bounded interval [0,4], there is at least one value of c in (a,b) for which:

$f(c) = \frac{1}{b-a}\int\limits^a_b {f(x)} \, dx$

In this problem, we have that:

$f(x) = x, a = 0, b = 4$

So $f(c) = c$

----------

$f(c) = \frac{1}{b-a}\int\limits^a_b {f(x)} \, dx$

$c = \frac{1}{4-0}\int\limits^0_4 {x} \, dx$

$c = \frac{1}{4-0}*8$

$c = 2$

The number c is 2.
