You would do 172 -8 and keep the i when you cancel the numbers out
Answer:
Babysitting =$8.7
Water park =$8.7
Step-by-step explanation:
In 1 week
Babysitting =3 hrs
Water park = 10 hrs
Total =$ 109
In week 2
Babysitting = 8 hrs
Water park = 12 hrs
Total= $ 177
Both weeks
Babysitting =11 hrs
Water park =22 hrs
Total=$286
33 hrs = $ 286
11 hrs =?
11×286÷33=$95.3
33 hrs = $286
22 hrs = ?
22×286÷33=190.7
Babysitting she got $95.3 in both weeks
Water park she got $190.7(rounded offf)in both weeks
11 hrs = $95.3
1 hr = ?
1×95.3÷11=8.7 (rounded off )
22 hrs = $ 190.7
1 hr = ?
1×190.7÷22= 8.7( rounded off)
There are a couple of ways you can solve this. You can write it out like
(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)(K-3)
And pretty much use the foil method
Or you can use the binomial theorem (google it if you dont know)
The solution should be:
(K^7) - 21(k^6) + 189(k^5) - 945(k^4) + 2835(k^3) - 5103(k^2) + 5103k - 2187
A) Let x stand for time, y stand for velocity.
We are given the points (2,50), (6, 54). We can make a line using the slope intercept form
y = mx + b.
slope is (54 - 50)/(6-2) = 4/4 = 1
y = 1x + b
plug in point (2,50) to find b
50 = 1(2) + b
50-2 = b
48 = b
the equation is y = 1x + 48
Make standard form.

Answer:
x=1 and x=-4
Step-by-step explanation:
Put it into your calculator, go to graph and look at which points it says ERROR.
