Answer:
When you have a equation such as
y = 2x + 4
This means, that whatever x equals, do the rest equation for y. They give you a table, the numbers under x, you replace x with the x in the equation. Multiply it next to the number. Do the rest of the equation, that is how you get y.
Once you do all x numbers, you have to graph it.
X = run
Y = rise
X is the horizontal line
Y is the vertical line

Look at the middle, the x numbers that are to the right of the vertical line are negative.
The ones to the left are positive.
The numbers that are on the top of y are positive
The numbers that are on the bottom are negative.
Hope this helps!

Step-by-step explanation:
i don't know if this is correct but you have to divide 16 from 24. sorry if this is wrong im trying to do the best i can.
Answer:
1. Add 5 to both sides
2. Divide both sides by 2
3. Take the square root of both sides
4. Subtract 2 from both sides
Step-by-step explanation:
2(x+2)²-5=93
<em>Add 5 to both sides</em>
2(x+2)²=98
<em>Divide both sides by 2</em>
(x+2)²=49
<em>Square root both sides</em>
x+2=7
<em>Subtract 2 from both sides</em>
x=5
Answer:
The range is -6, 4 , 12.
Step-by-step explanation:
If the domain is -4,0,5, x can only be -4 or 0 or 5.
Substitute each of these x-values into the equation 12x+6y=24. Then isolate to find the possible values of x.
Sub x for -4
12x+6y=24
12(-4)+6y=24
-48+6y=24
6y = 72
y = 12
Sub x for 0
12x+6y=24
12(0)+6y=24
6y = 24
y = 4
Sub x for 5
12x+6y=24
12(5)+6y=24
60 + 6y = 24
6y = -36
y = -6
The possible values of y are -6, 4 ,12 which is the range.
In set notation: R = {y|y=-6,4,12}
