Answer:
distributive property
Step-by-step explanation:
each term in the parenthesis is multiplied by the 12 outside
12(x + 4) = 12x + 48 ← using the distributive property
Answer:
-1, 0, 1
Step-by-step explanation:
the blue and red lines overlap to give a solid dot above -1 through to 2, which has an open dot above
therefore, -1 ,0, 1 are the only integers that would be in the solution set
<h3><u>The value of y is -2.5</u></h3><h3><u>The value of x is -2.</u></h3>
x - 8y = 18
-16x + 16y = -8
We can multiply each term in the first equation by 2 to better assist this elimination.
2x - 16y = 36
Now, we can use elimination.
Add equations together.
-14x = 28
Divide both sides by -14
x = -2
Now that we have a value for x, we can solve for y.
-2 - 8y = 18
Add 2 to both sides.
-8y = 20
Divide both sides by -8
y = -2.5
After 5 months you will have $160
so,
10
10×2 =20
20×2=40
40×2 =80
80×2=160
hence proved that after 5 months you will have $160
