Answer:

x = 5

Step-by-step explanation:

4(6x -10) = 8x + 40

24x - 40 = 8x + 40

now were going to get the variable and the numbers on different sides

24x - 40 + 40 = 24x

8x + 40 - 8x = 40

24x - 8x = 16x

40 + 40 = 80

16x = 80

now divide each side by 16

16x / 16 = x

80 / 16 = 5

x = 5

The polynomial f(x) is written in factored form:
qaws [65]

Answer:

x = 6, x = -5, x = 9

if f(x)=(x-6)(x+5)(x-9)

Step-by-step explanation:

The zeros of a polynomial in factored form can be found by setting the polynomial equal to zero and then realizing if a product is zero, then at least one of it's factors is zero.

So we have the zero's are the x's that satisfy

(x-6)(x+5)(x-9)=0.

We just need to solve three equations:

x-6=0

           This can be solved by adding 6 on both sides:  x=6

x+5=0

         This can be solved by subtracting 5 on both sides: x=-5

x-9=0

         This can be solved by adding 9 on both sides: x=9

The solutions are in { 6,-5,9 }.

How would I work this question? x+10y= -9 and x=5y+21
MatroZZZ [7]

Answer:

what you do is you want to get the x by it self so you would subtract the x and put it on the other side. like this: 10y=-9-x. OK so you would subtract -9 and put it on the other side like this: 9 + 10y=-x. but you can't have a negative x so u would do -9 + 10y=x.
