-4(9n + 9) = -12(4n - 6).

Mathematics
1 answer:
WITCHER [35]3 years ago
7 0

Answer:

n = 9

Step-by-step explanation:

Step 1: Write equation

-4(9n + 9) = -12(4n - 6)

Step 2: Solve for <em>n</em>

<u>Distribute:</u> -36n - 36 = -48n + 72

<u>Add 48n to both sides:</u> 12n - 36 = 72

<u>Add 36 to both sides:</u> 12n = 108

<u>Divide both sides by 12:</u> n = 9

Step 3: Check

<em>Plug in n to verify if it's a solution.</em>

-4(9(9) + 9) = -12(4(9) - 6)

-4(81 + 9) = -12(36 - 6)

-4(90) = -12(30)

-360 = -360

Find 5 points that satisfy the equation y= 12+2x
Goshia [24]
We start by finding the intercept of the line: what does y equal when x=0? and what does x equal when y=0?
• intercept in x
y = 12 + 2x
0 = 12 + 2x
-12 = 2x
-6 = x
• intercept in y
y = 12 + 2x
y = 12 + 2(0)
y = 12 + 0
y = 12
Now we find three more points giving y a value and finding x
y = 12 + 2x
2 = 12 + 2x
2-12 = 2x
-10 = 2x
-5 = x

y = 12 + 2x
6 = 12 + 2x
6 - 12 = 2x
-6 = 2x
-3 = x

y = 12 + 2x
14 = 12 + 2x
14 - 12 = 2x
2 = 2x
1 = x

Notice how I gave y even numbers as values since we would have to divide with 2 at the end.

Sol. {(-6,0)(0,12)(-5,2)(-3,6)(1,14)}
