Answer:

The elevator started at floor 7

Step-by-step explanation:

The y-intercept is when x is 0

In this situation x represents time, so when no time has passes yet y is at 7

This means that the elevator was at floor before any time passed (before it started moving)

hope this helps, lmk if it doesnt :)

C is clicked but I'm not sure if that is the answer I just clicked one. I need the answer to both.

Answer:

I believe that B is the correct answer!

Step-by-step explanation:

The (x+5) can cancel

Then in the numerator (x^2-25) can be factored into (x-5)(x+5) through difference of squares.

Then in the denominator the (x-5)^2 can be stretched out to (x-5)(x-5)

Lastly the (x-5) on the top and bottom will cancel resulting in result B

I hope this helped!

The length of a rectangle is 5 centimeters less than twice its width. The perimeter of the rectangle is 80 cm. What are the dime

Nat2105 [25]

Let the width be x

The length would be 2x-5

So, 2(x+2x-5)=80

3x-5=40

3x=45

x=15.

So the width is 15 and the length would be 25.

What is the remainder R when the polynomial p(x) is divided by (x + 1)? Is (x + 1) a factor of p(x)? p(x) = -3x4 + 2x3 - x2 + 6

Answer:

(x+1) is a factor with remainder 0.

Step-by-step explanation:

We divide (x+1) into the polynomial $-3x^4+2x^3-x^2+6$ through long division or synthetic. We choose long division and look for what will multiply with (x+1) to make the polynomial $-3x^4+2x^3-x^2+6$ .

$(x+1)(-3x^3)=-3x^4-3x^3$

We subtract this from the original $-3x^4-(-3x^4)+2x^3-(-3x^3)-x^2+6$ .

This leaves $5x^3-x^2+6$ . We repeat the step above.

$(x+1)(5x^2)=5x^3+5x^2$ .

We subtract this from $5x^3-(5x^3)-x^2-(5x^2)+6=-6x^2+6$ . We repeat the step above.

$(x+1)(-6x)=-6x^2-6x$ .

We subtract this from $-6x^2-(-6x^2)+0x-(-6x)+6=6x+6$ . We repeat the step above.

$(x+1)(6)=-6x+1$ .

We subtract this from $6x-(6x)+6-(6)=0$ . There is no remainder. This means (x+1) is a factor.
