Y=30x+18
well if he didn't deliver to any houses he would be paid 18$.
Answer:
9) Vincent will not get the correct answer because the + 484 is unneccesary, as he already subtracted it.
10a) 310,000 + x = 465,000; so x = 155,000
10b) 930,000/310,000 = 3 times more
Step-by-step explanation:
Answer:
- equivalent rate: 7.186%
- compounded 16 times
Step-by-step explanation:
The equivalent interest rate is the rate that would have to be applied so it would earn the same amount in 1 year. It is computed from ...
requiv = (1 +r/n)^n -1
requiv = (1 +0.07/4)^4 -1 ≈ 7.186%
__
"Compounded quarterly" means interest is compounded 4 times per year. In 4 years, it will be compounded 4·4 = 16 times.
__
The balance in the account after 4 years is ...
$600·(1 +.07/4)^(4·4) ≈ $791.96
You can do anything to an equation as long as you do it to both sides
for inequalities, when multiplying or dividing both sides by a negative, flip the sign
1/3(-5x-3)<14
times both sides by 3/1
-5x-3<14
add 3 to both sides
-5x<17
divide both sides by -5
flip sign
