Answer:
The slope is 2 and the y-intercept is -6
Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

where
m is unit rate or the slope of the linear equation
b is the y-intercept or initial value (value of y when the value of x is equal to zero)
In this problem we have

therefore
the slope is equal to

and

<u><em>Verify</em></u>
For x=0
---> is ok
Answer:

Step-by-step explanation:
The vertex form of an equation of a parabola:

(h, k) - vertex
We have

We must use the formula: 

Use the distributive formula a(b + c) = ab + ac

509 ÷ 13 = 36.36
There are about 36 floors.
Answer: 36 floors.
1. You have that a<span> student's pay of $18 an hour </span>is <span>$4 more than twice the amount the student earns per hour at an internship.
2. So, let's call the </span><span>hourly pay of the internship: "x". Then, you have:
</span><span>
18=2x+4
3. When you clear the variable "x", you obtain:
18-4=2x
14=2x
x=14/2
x=$7
Therefore, the answer is: T</span><span>he hourly pay of the internship is $7.</span>
F(x)=5x
normal domain: all real numbers
practical domain: <span>all positive integers
</span>becasue we can substituent with any positive integer in the place of x
