The answer is (5,3). You need to equal both sides out. So 5x-22=4x-17. That will give you x=5. After that you substitute 5 for x in one or both of the equations and get that y=3. Hope this helps!

If f(x)= - 4x-4, g(x)= 4x² + 4x + 2, and h(x)= 3x2 – 3, find f(3).
Deffense [45]

Answer:

f(3) = -16

Step-by-step explanation:

Given

f(x)= - 4x-4

g(x)= 4x^2 + 4x + 2

h(x)= 3x^2 - 3

Required

f(3)

We have:

f(x)= - 4x-4

Substitute x = 3

f(3) = -4 * 3 - 4

f(3) = -12 - 4

f(3) = -16

Hence:

f(3) = -16

Bezzdna [24]

Answer:

x-30

Step-by-step explanation:

Firstly, you do the first step, which is, 3x-18+4x+12-6x, then you continue simplifying it: 7x-18+12-6x.

Keep it on and on, the next step: x-18+12, add 18 and 12 together you get 30.

A line contains the points (8, 9) and (–12, –7). Using point-slope form, write the equation of the line that is parallel to the
kozerog [31]
For the answer to the question above,
The slope of the line of the line is calculated through the equation,
m = (y2 - y1) / (x2 - x1) 

Using the first two points in the given,
 m = (-7 - 9) / (-12 - 8) = 4/5

The line parallel to this has also a slope of 4/5. Through the point-slope form, the equation of the second line is,
 y - -15 = (4/5)(x - -5)

Simplifying gives the answer of,
y = (4/5)x -11

Eliminating the fraction, 
5y = 4x - 55

I hope my answer helped you.
