What is the factored form of x2 – X– 2? (x - 2)(x + 1) (x + 2)(x + 1)

solmaris [256]

Answer:

(x+2)(x-1)

Step-by-step explanation:

One way to factor is to FOIL your answer choices:

First: x(x)

Outer: x(-1)

Inside: 2(x)

Last: 2(-1)

Combine these values together and you get

x^2-x-2

the amount p (in dollars) that you earn by working h hours is represented by the equation p=9h. graph the solution and interpret

stealth61 [152]

The slope (9) is the amount of money you earn per hour, hence multiplying the amount by h, hours.

I've included a picture of the graph below.

Lara found the volume of a sphere with a diameter of 10.

Paraphin [41]

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

$V=\frac{4}{3}\pi r^{3}$

we have

$r=10/2=5\ units$ ----> the radius is half the diameter

substitute

$V=\frac{4}{3}\pi (5)^{3}$

$V=\frac{500}{3}\pi\ units^{3}$

Answer:

The equation in slope-intercept form of required line is: $\mathbf{y=\frac{2}{3}(x)-6}$

Step-by-step explanation:

We need to write equation in slope-intercept form to represent the line on the graph.

The general equation in slope-intercept form is: $y=mx+b$

Where m is slope and b is y-intercept

Finding slope using formula: $Slope=\frac{y_2-y_1}{x_2-x_1}\\$

Looking at he graph we have

$x_1=3, y_1=-4, x_2=6, y_2=-2$

Putting values in formula and finding slope:

$Slope=\frac{-2-(-4)}{6-3}\\\\Slope=\frac{-2+4}{3}\\Slope=\frac{2}{3}$

So, we get slope m = 2/3

Using slope m=2/3 and point (3,-4) we can find y-intercept

$y=mx+b\\\\-4=\frac{2}{3}( 3)+b\\-4=2+b\\b=-4-2\\b=-6$

So, y-intercept b = -6

The equation of line having m=2/3 and b=-6 will be:

$y=mx+b\\y=\frac{2}{3}(x)-6$

The equation in slope-intercept form of required line is: $\mathbf{y=\frac{2}{3}(x)-6}$
