Answer:
C) y = 1/3x - 6
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
1/3=m
-6=b
then plug in the numbers to get: y=1/3x - 6
Hope this helps! :)
Answer:
x = 3, y = 3, z = - 2
Step-by-step explanation:
Given the 3 equations
x - y - 2z = 4 → (1)
- x + 3y - z = 8 → (2)
- 2x - y - 4z = - 1 → (3)
Add (1) and (2) term by term to eliminate x
2y - 3z = 12 → (4)
Multiply (1) by 2 and add to (3) to eliminate x
2x - 2y - 4z = 8 → (5)
Add (3) and (5) term by term to eliminate x
- 3y - 8z = 7 → (6)
Multiply (4) by 3 and (6) by 2
6y - 9z = 36 → (7)
- 6y - 16z = 14 → (8)
Add (7) and (8) term by term to eliminate y
- 25z = 50 ( divide both sides by - 25 )
z = - 2
Substitute z = - 2 into (7)
6y + 18 = 36 ( subtract 18 from both sides )
6y = 18 ( divide both sides by 6 )
y = 3
Substitute y = 3 and z = - 2 into (1)
x - 3 + 4 = 4
x + 1 = 4 ( subtract 1 from both sides )
x = 3
Solution is x = 3, y = 3, z = - 2
Answer:
450 banana cream pies
Step-by-step explanation:
Total number of pies in a month = 1500;
this represents 100% of the pies
Out of the total pies in a month, the proportion of banana cream pies = 30%
Next, find the number of banana cream pies ;
# of Banana pies = proportion of banana pies * total number of pies
=30% *1500
= 450
Therefore, the banana cream pies sold were 450.
