Answer:

c × 0.90

Step-by-step explanation:

c × 0.90, would be your answer because 10% is equal to 0.10, then you would subtract the 0.10 (10%) by 1 (100%), then multiply c times the 0.90 that you get, to get the decreased number, because you're multiplying by a decimal

What is the product? 2y/y-3 x 4y-12/2y+6

Sphinxa [80]

Answer: The product of the above polynomials will be

$\frac{4y}{y+3}$

Step-by-step explanation:

Since we have given that

$\frac{2y}{y-3}\times \frac{4y-12}{2y+6}$

We need to solve the product of two polynomials :

$\frac{2y}{y-3}\times \frac{4y-12}{2y+6}\\\\=\frac{2y}{y-3}\times \frac{4(y-3)}{2(y+3)}\\\\=\frac{4y}{y+3}$

Hence, the product of the above polynomials will be

$\frac{4y}{y+3}$

The quadratic regression graphed on the coordinate grid represents the height of a road surface x meters from the center of the

Viktor [21]

Answer:

The height of the surface increases, then decreases, from the center out to the sides of the road.

Step-by-step explanation:

Let

y------> the height of the surface

x------> the road

we know that

The quadratic regression graphed represent a vertical parabola open downward

The function increase in the interval --------> $[-5,0)$

The function decrease in the interval --------> $(0,5]$

therefore

The height of the surface increases, then decreases, from the center out to the sides of the road.

Is this how you get the slope intercept form?

Komok [63]

Slope-intercept form : y = mx + b

3) y + 4 = x

So, you need to move 4 to the other side, so that y is by itself.

Subtract 4 from both sides.

y = x - 4
