Answer:
Step-by-step explanation:
First the solution to the equation
-4y = x - 18 Divide by - 4. Watch your signs.
-4y / -4 = x/-4 + 18/-4 Do the division. Notice the 18 needs to be divided by - 4 as well as the other two terms.
y = (-1/4)x - 4.5
Second the graph. See below.
Your original equation is what was graphed.
Third: The table with the points added to the graph.
Sample Calculation
x = 10
-4y = 10 - 18
-4y = - 8
y = -8/-4
y = 2
Point (10,2)
The graph on the right includes the table with 3 points plotted.

Answer:
Step-by-step explanation:
<h3><u>Given functions:</u></h3>- f(x) = 4x² - 6
- g(x) = x² - 4x - 8
Subtract both functions
(f-g)(x) = 4x² - 6 - (x² - 4x - 8)
(f-g)(x) = 4x² - 6 - x² + 4x - 8
Combine like terms
(f-g)(x) = 4x² - x² + 4x - 6 - 8
(f-g)(x) = 3x² + 4x - 14
Hmm they're both even numbers so maybe we can start by cutting each number in half.
18 and 48 had 2 as a common factor.
So factoring a 2 out of each number was the same as cutting each number in half. Try to do something similar with the 9 and 24. They each have something in common.
