Y=mx+b
m=slope, b=y-intercept
m=(y2-y1)/(x2-x1), b=value of y when x=0
m=(3--1)/(-2-4)
m=4/-6
m=-2/3, now we have:
y=-2x/3+b, we can solve for b using any point, I'll use (4,-1)
-1=-2(4)/3+b
-1=-8/3+b
-3/3+8/3=b
5/3=b so
y=-2x/3+5/3
Answer:
P + M = 30
700P + 200M = 15000
Number of laser printers = 18
Number of color monitors = 12
Step-by-step explanation:
Let P = number of laser printers
Let M = number of color monitors
Given total number of boxes = 30
⇒ P + M = 30
Given:
- $700 = cost of laser printer
- $200 = cost of color monitor
- $15000 = total cost of order
⇒ 700P + 200M = 15000
Rewrite P + M = 30 to make P the subject:
⇒ P = 30 - M
Substitute into 700P + 200M = 15000 and solve for M:
⇒ 700(30 - M) + 200M = 15000
⇒ 21000 - 700M + 200M = 15000
⇒ 500M = 6000
⇒ M = 12
Substitute found value for M into P = 30 - M and solve for P:
⇒ P = 30 - 12 = 18
Answer:
She had to pay for 24.
Step-by-step explanation:
Multiply 3 by 8
Equals 24
For every 3 cans she gets one free
4 times 8 equals 32
So she payed for 24 and got 8 free
