So for this you need the two solutions to be x= -9 and x=3 then move over the numbers and put in brackets (x+9)(x-3) then multiply together x^2+9x-3x-27 then combine like terms to get x^2+6-27

The table below represents a linear function f(x) and the equation represents a function g(x):
gulaghasi [49]
First, lets solve f(x). g(x) is already given. Find the slope of f(x) by doing m = y2-y1/x2-x1. I'm going to use -1,-5 (1) and 0,-1 (2). -1-(-5) = 4 and 0-(-1) = 1. This means that the slope is 4 since 4/1 = 4.
Now find y intercept (b). Since we know that y=4x+b, we can solve this by plugging in an ordered pair. I will use -1,-5. -5 = 4(-1) +b. With this, we see that -5 = -4+b and b = -1 since -5 = -4-1.
Your equation for f(x) is y=4x-1. 
A: The slopes are equal since both of them are 4.
B: g(x) has a greater y intercept since 3 > -1.

I'm bad at math so uh yeahhh
____ [38]

Answer and Step-by-step explanation:

Since we know that lines <em>l</em> and <em>m</em> are parallel (we are just proving that they are parallel), we can see that the two angles given are corresponding angles, so they are congruent to each other.

123 = 2x + 7

<u>Subtract 7 from both sides.</u>

116 = 2x

<u>Now, divide both sides by 2.</u>

58 = x

<u>So, the value of x is 58.</u>

Find the equation of the line using the given information.
Dominik [7]

Answer:

x 1 = -3  

x2 = -3

y1 = 0

y2 = 5

The slope of that equation is infinite and the equation is a perfectly vertical line at x = -3.

So, the equation is x = -3.
