Answer:
initial value is 21
Step-by-step explanation:
y=mx+b
6= -3(5) +b
b=21
Answer:
3
Step-by-step explanation:
Again, anything to the 0th power is equal to 1.
The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.
Now you can subtract 9 from 12 to get 3 as your final answer.
Answer:
x=8,y=-1
Step-by-step explanation:
x-2y=10
x=10+2y
10+2y+3y=5
5y=-5
y=-1
x-2(-1)=10
x=8
Answer:

Step-by-step explanation:
Let
x ----> amount that Jethro owes in taxes
we know that
Amount that he made last year 
His tax rate 
Applying proportion
solve for x

They sold 187 small bags and 75 large bags.
Two variables L and S (large & small)
We know that L + S = 262 -> the amount of bags sold
We also know that 3L + 1S = $412 -> total money made
L = 262 - S
Plug that into the second equation:
3(262 - S) + 1S = 412
786 - 3S + 1S = 412
786 - 2S = 412
786 - 412 = 2S
374 = 2S
S = 187
187 small bass and
So they sold 187 small bags
L = 262 - 187 = 75
They sold 75 large bags.
