For this case we must find the solutions of the following inequality:

(x-3)(x+5)\leq0

For (x-3)(x+5)=0we have the following solutions:

x=3\\x=-5

As a possible solution we have the following intervals:

x\leq -5\\-5\leq x\leq 3\\x\geq 3

We must choose a value included in each of the possible intervals, replace them in the original inequality and verify if it is fulfilled.

  • x\leq -5

(-6-3)(-6+5)\leq 0\\-9*-1\leq0\\ 9\leq0

It is not true

  • -5\leq x\leq 3

(0-3)(0+5)\leq 0\\-3*5\leq 0\\-15\leq0

It is true.

Answer:

C

Step-by-step explanation:

If this was an equation...

(x-3)(x+5) = 0

x = 3, -5

So 3 and -5 are the minimum and the maximums.

So we convert that into an inequality.

-5 <= x <= 3

You basically plug in the x in the equation, for example if x = 4 and the equation is y = 2x + 5 you plug in 4 and the equation becomes y = 2(4) + 5. you then multiply and get y=8+5. from here u just add it and u get ur answer

Subtract.<br> 5x – 6x+2<br> - 1-2x - x - 2)
adell [148]

Answer:

7x^2 -5x + 4

Step-by-step explanation:

5x^2 – 6x+2

- (-2x^2 - x - 2)

We got 5x^2 - (-2x^2) = 5x^2 + 2x^2 = 7x^2

-6x - (-x) = -6x + x = -5x

2 - (-2) = 2+2 = 4

So the equation would be 7x^2 -5x + 4

Hope this help :3
