The answer is 9 because you solve it from left to right and 3x5 equals 15, 15 subtracted by 6 equals 9

Answer:

3x ≤ - 6

Step-by-step explanation:

let the number be x.

three times of it would be 3x

since 3x is at most -6, 3x must be less than or equal to -6.

hence, 3x ≤ -6

however, your option seems to not have any sign that has equal to so perhaps the nearest answer would be 3x < -6

How many x intercepts does the polynomial function y=(x-8)(x+3)^2

guajiro [1.7K]

Answer:

The answer is 2 x-intercepts

Step-by-step explanation:

To determine the x-intercepts we set y to zero and solve for x:

y=0

(x-8)(x+3)^2=0

The product of 2 factors is 0 means that one of them must be 0:

x-8=0 ⇒ x=8 →first x-intercept

or (x+3)^2=0 ⇒ x+3=0 ⇒ x=-3 →second x-intercept

Therefore the polynomial function two roots, so it has two x-intercepts x=8 and x=-3

Hope this helps :)

I don't understand how to do this, can someone please help me?

denis23 [38]

Answer:

x=1

Step-by-step explanation:

First find a common denominator between 7 and 4 which is 28, Multiply both equations by 28 eliminating the denominators so now you have theses two equations: 4(2x + 12) = 7(3x + 5) distribute these equations to get:

8x + 48 = 21x +35 now you want to get the x's on one side so 8-21 = -13 which as an equation so far would be -13x + 48 = 35 now do 35-48 = -13 so you can have 13x alone on one side. Your final equation now before you solve is

-13x = -13 the divide -13 by -13 to get 1.

Hope this helps you understand it better
