Answer:−3+3=−4
2+3−=15
4−3−=19
2 3
Step 1: Pair the equations to eliminate y because the y terms are already additive inverses
1
−3+3=−4
2+3−=15
2
2+3−=15
4−3−=19

6 −2=34
Step 2: Write the two new equations
as a system
Step 3: Substitute the value for x and z
into one of the original equations
3 =11
3 5 +2=11

The solution (5, 1, -2)
Step-by-step explanation:
The amount of chlorine needed to treat a swimming pool is directly proportional to the volume of the poolWhat is the constant of proportionality for this relationship
Answer:
a)
Step-by-step explanation:
On the x-axis, y = 0
y = -3x -18
0 = -3x -18
3x = -18
x = -6
(-6,0)
Answer:
$3
Step-by-step explanation:
3 dollars because
1 pound = 16 ounces
and 1 pound costs 1.5 dollars
if there are 32 ounces of broccoli, you divide the number of ounces by 16 and multiply that by 1.5
32/16 = 2 x 1.5 = 3
