Answer:
f(x)=-3x+4
(can't see some of your choices)
Step-by-step explanation:
We want x to be independent means we want to write it so when we plug in numbers we can just choose what we want to plug in for x but y's value will depend on our choosing of x.
So we need to solve for y.
9x+3y=12
Subtract 9x on both sides
3y=-9x+12
Divide both sides by 3:
y=-3x+4
Replace y with f(x).
f(x)=-3x+4
The goal is to solve for y. Start by subtracting 2x from both sides. This gives you 8y=-2x+16. Now just divide both sides by 8, which gives you y=-2/8x+16/8. Finally, simplify this to y=-1/4x+2.
Answer:
I = $4204.8
Step-by-step explanation:
Given that,
Principal, P = $43,800
Interest rate = 4.8%
Rate = 2 years
We need to find the interest that is paid back. We know that, simple interest is given by :

Put all the values,

So, the required interest is equal to $4204.8

If Jayden needs 900, and he already has 375, first you need to find out how much more money he needs. Do that first.
2. His job pays him 155 a week, so 155w. If he needs to make at least 900, that means that it would be ok if he earned equal to 900, or more. So the amount he earns is greater than or equal to 900.
3. Solve for w. This should give you your answer.
I hope this helps!
