Answer:

Step-by-step explanation:

1. x+6=14

14-6=8

x=8

2. 15/x=3

15/3=x

x=5

3. 7*x=56

56/7=8

x=8

4. x^2-4=12

x=4, x=-4

5. 1/4x=10

x/4 = 10

x = 40

6. 3x-9=18

x=9

7. 1/2x-10=14

x/2-10=14

x=48

8.x/8=9

8*9=72

x=72

9.2x+3=24

2x=21

x=21/2

10.20*x=140

140/20=7

x=7

Write as a product: −y^3+xy^2−4x+4y

Semmy [17]

Answer:

$(x-y)\left(y^{2}-4\right) \text { is the product of }-y^{3}+x y^{2}-4 x+4 y$

Step-by-step explanation:

$\text { Given equation is }-y^{3}+x y^{2}-4 x+4 y$

$\text { Writing all }^{a} x^{\prime \prime} \text { terms and "y" terms at a place. }$

$\left(-4 x+x y^{2}\right)+\left(4 y-y^{3}\right)$

Now take “x” common in the first term and “y” common in second term then the equation becomes as follows:

$x\left(-4+y^{2}\right)-y\left(-4+y^{2}\right)$

$x\left(y^{2}-4\right)-y\left(y^{2}-4\right)$

$(x-y)\left(y^{2}-4\right)$

$\text { The product of the given equation is }(x-y)\left(y^{2}-4\right)$

Which of the following is a zero does the function f (x) =(x+3) (x-7) (x+5)

Over [174]

Answer:

x=-3

Step-by-step explanation:

$(x + 3)$

x+3=0

-3 -3

x= -3

opposite of addition would be subtraction. since your trying to solve for x You want to get x alone and you subtract by 3 on both sides which would cancel the 3 on the left, leaving:

$x = - 3$

if you follow the same process on all of them you come to the conclusion that only -3 is a zero in the options listed.

NOTE: When you become more experienced whenever you see expressions like that you'll come to realize that the zero is the opposite sign of the number if it's just x- or x+ a number.

example:

$(x - 40)$
