Answer:

-3

Step-by-step explanation:

(0, 4) and (2, -2) are points on the line, plug these points in the slope formula

$\frac{-2-4}{2-0}$

$\frac{-6}{2}$ --> $\frac{-3}{1}$ =-3

Answer:

The slope of this is -3

Step-by-step explanation:

slope = change in y/ change in x or rise/run!!!

you move 3 down and 1 to the right. So basically -3/1 which can be simplified to -3!!!!

8) The perimeter of a rectangle is 20x2 + xy - 7y2 and one of it's sides is

Sedbober [7]

Answer:

3x^2 + 3xy/2 - 7xy^2/2

Step-by-step explanation:

So we know the perimeter is 20x^2 + xy - 7y^2,

To find any perimeter you need 2l + 2w = P so,

One of the sides is 7x^2 - xy

First plug in the values,

2(7x^2-xy) + 2w = 20x^2 + xy - 7y^2

Multiply,

14x^2-2xy + 2w = 20x^2 + xy - 7y^2

Subtract,

14x^2 - 2xy - 14x^2 + 2xy + 2w = 20x^2 + xy - 7y^2 - 14x^2 + 2xy

2w = 6x^2 + 3xy - 7y^2

w = 3x^2 + 3xy/2 - 7xy^2/2

Can somebody help me with this?

Juli2301 [7.4K]

Answer:

E) 1/2

Step-by-step explanation:

This is no ordinary problem. It actually requires you to solve two different problems in order to figure out the correct answer.

First, we must figure out what the hypotenuse of the triangle is. We have the two small sides (5 and 12), but don't have the larger side. To find this, we must use the Pythagorean theorem: $a^{2} + b^2 =c^2$

Let's plug in our a and b values

$5^2 + 12^2 = C^2$

Simplify

$144 + 25 = c^2$

$169 = c^2$

Square both sides

$c = 13$

But sadly, we aren't done yet. Now we know the length of the whole hypotenuse side. Time to figure out what X is by a simple equation.

$12x + 14x = 13$

Simplify

$26x = 13$

Divide by 26

Answer is 1/2

Expand (3x+7)(3x-7) =

saveliy_v [14]

Answer:

$9 {x}^{2} - 49$

Step-by-step explanation:

Do FOIL, first outside inside last

3x × 3x = 9x^2

3x × -7 = -21x

7 × 3x = 21x

7 × -7 = -49

$9 {x}^{2} - 21x + 21x - 49 \: midde \: cancels \: each \: other \: out$

So it would just be 9x^2 - 49
