Step-by-step explanation:
$866.704 is what she paid
Discount was $433.286
Answer:
(-3a -3b -5)
Step-by-step explanation:
So you have to add numbers with same valuables
- 8a+(-11a) Answer: -3a
- 2b+(-5b) Answer: -3b
- -9+4 Answer: -5
Uh.... She would have no money.
42 + (-65) = ?
= -23
Did you write the problem wrong?
Answer:
-39
Step-by-step explanation:
![\left(-3\right)^3-\sqrt[3]{27}-4^3\left(\sqrt[3]{64}-\left(2\right)\left(2\right)\right)-\frac{\left(3\right)^3\left(2\right)}{6}](https://tex.z-dn.net/?f=%5Cleft%28-3%5Cright%29%5E3-%5Csqrt%5B3%5D%7B27%7D-4%5E3%5Cleft%28%5Csqrt%5B3%5D%7B64%7D-%5Cleft%282%5Cright%29%5Cleft%282%5Cright%29%5Cright%29-%5Cfrac%7B%5Cleft%283%5Cright%29%5E3%5Cleft%282%5Cright%29%7D%7B6%7D)
Which gives us -39.
Answer:
150
Step-by-step explanation:
Since y is directly proportional to sqrt((x+2)^2), there is a constant,k, such that
y=ksqrt((x+2)^2)
We are given a pair (x,y) in this relation. Let's plug in (8,250 ) to find k.
250=ksqrt((8+2)^2)
250=ksqrt((10)^2)
250=k10
250/10=k
25=k
So for any pair (x,y) we have the relation y=25((x+2)^2).
We are asked to find y when x=4.
y=25((4+2))^2
y=25(6)
y=150
Test to see if y is proportional to sqrt((x+2)^2)
For the given points: 250/150=10/6
The equation is true so we're great.
