Answer: x = 3

Step-by-step explanation:

First you need to start by adding positive 4x to both sides since the 4x is a negative. 4x + (-7x) = -3x. Then it is just simply -3x+2 = -7. Since 2 is a positive number subtract both both sides by 2. Then you should get -3x = -9. Then divide both sides by -3 and the answer is x = 3.

Solve -3(h-6)=5(2h+3)

e-lub [12.9K]

Answer: 3/13

Step-by-step explanation:

-3 (h-6) = 5 (2h + 3)

-3h + 18 = 10h + 15

-3h - 10h + 15 - 18

h (-3-10) = 15 - 18

h (-13) = -3

h = -3/-13

What is the relationship between the factors and the graph of a polynomial equation??

bija089 [108]

Answer:

Each intercept corresponds to a zero of the polynomial function and every zero yields a factor.

Step-by-step explanation:

Each intercept corresponds to a zero of the polynomial function and every zero yields a factor, so we can now write the polynomial in factored form. Graphs behave differently at various intercepts. Sometimes, the graph will cross over the horizontal axis at an intercept. Other times, the graph will touch the horizontal axis and bounce off.

This is a combination problem requiring a combination solution with the following formula and steps:

C (n, r) =? C (n, r) = ?

n choose r

n (objects) = 16

r (sample) = 5

C (n, r) =? C (n, r) = ?

C (n, r) =C (14,5) C (n, r) =C (16,5)

=16! (5! (16−5)!) =16! (5! (16−5)!)

= 4368
