We know that the area of a parallelogram is the base * the height of it, so if we divide both sides by the height, then area/height=base. Therefore, we must divide the area by the height. To divide using polynomials, we first set it up similar to a regular long division problem:

______________________

2x+3 | 2x²+13x+15

Next, we take the first component of the numerator (2x² in this case) and divide it by the first component of the denominator (2x) to get x. That will form the start of our answer, and at the bottom, we will subtract our numerator by the denominator (2x+3) multiplied by the start of our answer (x). Therefore, we have

_x_____________________

2x+3 | 2x²+13x+15

-(2x²+3x)

_______________

10x+15

We then repeat the process until we finish, and whatever's left at the top is our answer. If there's something left, that's our remainder.

_x+5_____________________

2x+3 | 2x²+13x+15

-(2x²+3x)

_______________

10x+15

- (10x+15)

_________________

Therefore, our base has a length of x+5.

25 PTS!!!!y = 3x + 3 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form

Answers

remember that you can do anything to an equaiton as long as you do it to both sides
ok so subsitution
basiclalyy you subsitute a known thing for an unknown thing so
y=3x+3 and y=x-1
they both equal y so
3x+3=y=x-1
3x+3=x-1
subtract x from both sides
2x+3=-1
subtract 3 from bot sides
2x=-4
divide both sides by 2
x=-2
subsitute
y=x-1
y=-2-1
y=-3

the solution is x=-2 y=-3 so
(x,y)
(-2,-3)

WILL GIVE BRAINLIEST ANSWER! Given the parent function f(x)=|x|, which equation would occur if the function is vertically compressed by 13, shifted down 6 units, and shifted right 5?

f(x)=3|x+5|−6

f(x)=13|x−5|−6

f(x)=13|x+5|−6

f(x)=13|x−6|+5

Answers

$f(x)=13|x-5|-6$ is the equation represented by all the operations.

Step-by-step explanation:

The given function is

$f(x)=|x|$

It is vertically compressed by a factor of 13 then the function becomes,

$f(x)=13|x|$

It shifted down 6 units, then the function becomes,

$\mathbf{f}(\mathbf{x})=\mathbf{1 3}|\boldsymbol{x}|-\boldsymbol{6}$

It shifted right by 5 units then the function becomes,

$f(x)=13|x-5|-6$

Thus the resultant equation thus obtained is $f(x)=13|x-5|-6$
