Answer:
x = 1; y = 1; z = 0
Step-by-step explanation:
First problem:
First equation minus second equation: 3y + 2z = 3 Eq. A
Second equation plus third equation: 2y + 4z = 2 Eq. B
-2 times Eq. A plus Eq. B: -4y = -4
y = 1
Substitute y = 1 in Eq. A: 3 + 2z = 3
2z = 0
z = 0
Substitute z = 0 and y = 1 in original first equation:
-2x + 2 + 0 = 0
-2x = -2
x = 1
Answer: x = 1; y = 1; z = 0
Answer:
Step-by-step explanation:
A horizontal line is only concerned with the y value. The equation is y = 10 because that is the point that the line must go through.
The x value does not matter as long as the y value is given as 10. The domain is any real value. The range is 10

Answer:
The equation would be -x + 4y = -8
Step-by-step explanation:
To find the standard form of the line, solve for the constant.
y - 1 = 1/4(x - 12)
y - 1 = 1/4x - 3
-1/4x + y - 1 = -3
-1/4x + y = -2
-x + 4y = -8
Each must have 3
3 times number of studnets=popsicles she must buy
3 times 25=75
she needs 75 posicles
number of poples bought=number per box times number of boxes
needs 75
75=15 times number of box
divide both sides by 15
5=number of boxes
should buy 5 boxes
