-9x=-36

divide both sides by -9

to get x by itself

to get +x

-9x/-9= -36/-9

cross out -9 and -9, then becomes -1*-1*x= x

x= -36/-9

answer:

x= 4

Solve the following equation. Then place the correct mixed number in the box provided. 5x/7=22

natka813 [3]

We have that
 5x/7=22
multiply by 7 both sides
5x=22*7-------> 5x=154
divide by 5 both sides
x=154/5
x=30.8--------> x=30 4/5

the answer is
x=30 4/5

MODELING REAL LIFE A baseball is thrown up in the air. The table shows the heights $y$ (in feet) of the baseball after $x$ secon

nikklg [1K]

The equation for the path of the ball can be measured using a regression model calculator which produced the quadratic model ;

y(x) = - 16x² + 36x + 4
Height at x = 1.7 = 18.89 feets

The table given :

Time, x : __0.5 ___ 1 ____ 1.5 ____ 2

Height, y _ 18 ____22 ___ 24 ____ 12

Using technology such as a quadratic regression calculator or excel ;

The quadratic regression model obtained is :

y(x) = - 16x² + 36x + 4

The height after, 1.7 seconds, x = 1.7 can be calculated thus :

Put x = 1.7 in the equation :

y(1.7) = - 16(1.7)² + 36(1.7) + 4
y = 18.89 feets

Therefore, the height of the baseball after 1.7 seconds will be 18.89 feets.

Which polynomial is factored completely

Ket [755]

Answer: The correct option is c.

Explanation:

Reason for correct option:

$3x(9x^2+1)$

This expression cannot be factored further because $(9x^2+1)$ is the complete factor. Therefore the option c is correct.

Reason for incorrect option:

$5x^2-17x+14=5x^2-10x-7x+14=5x(x-2)-7(x-2)=(x-2)(5x-7)$

Since the given expression can be factored further therefore the option d is incorrect.

$4(4x^4-1)=4((2x)^2-1)=4(2x^2-1)(2x^2+1)$

Since the given expression can be factored further. Therefore the option a is incorrect.

$2x(y^3-4y^2+5y)=2xy(y^2-4y+5)$

Since the given expression can be factored further. Therefore the option b is incorrect.
