So first solve for x and y
add the 2 equations together

2x+x+y-y=-8-4
3x=-12
divide by 3
x=-4
subsitute
-4-y=-4
addd 4 to both sdies
-y=0

the solution is (x,y)  (-4,0) or D

So,

I have decided to use Elimination by Addition.

Add the two equations together
3x = -12

Divide both sides by 3
x = -4

Substitute -4 for x in the second equation.
-4 - y = -4

Add 4 to both sides
-y = 0
y = 0

Check
2(-4) + 0 = -8
-8 = -8 This checks.

-4 - 0 = -4
-4 = -4 This also checks.

The solution set for this system is as follows:
S = {(-4,0)}

<em>That would be option D.</em>

The Moores family paid $6 more for skate rentals than the Cotters did. Together the two families paid $30 for skate rentals. How
Mademuasel [1]
<span>Moores Family Paid = 6 dollars mores for skate rental than the cotters did.
30 dollars = the total amount they paid for skate rentals.
Let Family Moore have the variable X
Let the Family Cotters have the variable Y
=> x = y + 6
=> y = 30 – 6 / 2
First, let’s solve the Y
=> Y – 30 – 6 / 2
=> Y = 24 / 2
=> y = 12
Now, let’s solve for X
=> X = y + 6
=> x = 12 + 6
=> X = 18

The greatest integer that satisfies the inequality 1.6−(3−2y)&lt;5
Cerrena [4.2K]

Solve the inequality 1.6-(3-2y)<5.

1. Rewrite this inequality without brackets:

1.6-3+2y<5.

2. Separate terms with y and without y in different sides of inequality:

2y<5-1.6+3,

2y<6.4.

3. Divide this inequality by 2:

y<3.2

4. The greatest integer that satisfies this inequality is 3.

Answer: 3.

3. Which rule represents a linear function? Check all
Nady [450]
The answer is C

The answer is C because the function form for a linear function is f(x) = ax+b and the answer C has x which is the slope and -3 which would represent the y-intercept also known as b
