Answer:1)5x^2-11x

             2) x^2-3x

Step-by-step explanation:

1)(f+g)(x)

f(x)=3x-7

g(x)= 2x-4

[(3x-7)+(2x-4)](x)

3x^2-7x+2x6^2-4x

=<u>5x^2-11x</u>

2) (f-g)(x)

[(3x-7)-(2x-4)](x)

(3x-7-2x+4)(x)

3x^2-7x-2x^2+4x

x^2-3x

Does the ordered pair (−5,−5) satisfy the following system of equations?<br> {−3x−3y=125x+5y=−20
FrozenT [24]

Well, let's see. The problem gave you an ordered pair. In other words, you have an 'x' and a 'y' coordinate. All you need to do is put them into the equation.

Step-by-step explanation:

This means that instead of --

-3x - 3y = 125 + 5y = -20

We would have:

-3(-5)-3(-5) = 125(-5) + 5(-5) = -20

From here, you just simplify it into:

30 = -650 = -20

Since the values are not the same, the ANSWER is NO. The ordered pair does not satisfy the following system of equations.

Pls help! I need help with a and c I did b already!
laila [671]

Answer:

A= y= -2x+7.

B= y= -\frac{3}{2}x+ 6

Step-by-step explanation:

The linear equation is y=mx+b

A= y= -2x+7.

-2 represents he slope and 7 represents the y intercept.

B= y= -\frac{3}{2}x+ 6

-\frac{3}{2} is the slop and 6 is the y intercept.

Hope this helps :)

Kavi solved the system
Marianna [84]

Answer:

She should have substituted y = 17 - 2x in the first equation

Step-by-step explanation:

3x + 4y = 33

2x + y = 17

y = 17 - 2x

3x + 4(17 - 2x) = 33

3x + 68 - 8x = 33

5x = 35

x = 7

y = 17 - 2(7)

y = 3

x = 7, y = 3

Only one solution
