Answer:
(5,-3) if the system is
y=x-8
2x+3y=1
Step-by-step explanation:
I think the system is to read:
y=x-8
2x+3y=1.
Please correct me if I'm wrong.
I'm going to plug 1st equation into 2nd equation giving me:
2x+3(x-8)=1 ->I replaced y with (x-8).
Distribute:
2x+3x-24=1
Combine like terms:
5x-24=1
Add 24 on both sides:
5x=25
Divide both sides by 5:
x=5
If y=x-8 and x=5, then y=5-8=-3.
The solution is (5,-3).
Let w represent the number of weeks passed.
The amount of money Ed saved is 6w - 1 (I'm subtracting the one dollar that he owes to someone)
His sister saved 6w + 2.66 (I'm adding the money she already saved).
What value of w makes both expressions equal?
We need to solve the equation 6w - 1 = 6w + 2.66
Let's solve it.
If we subtract 6w from both sides, we get -1 = 2.66
So, there is no solution. They will never have saved the same amount.
This makes sense because they started out with different amounts of money saved, but they are saving at the same rate.
Well, is not a product, just a sum of three terms, so to simplify simply expand and combine them as constants,
3² + 3⁴ + 3⁷
9 + 81 + 2187
2277
The answer is b both have 5 on the x
