Answer:
-0.87 has the strongest linear relationship
Step-by-step explanation:
-0.87, since it is the closest value to either one or negative one,
0.8 is the second strongest
0.65 is the third strongest
-0.52 is the least strongest
Answer: 2z+4/y+7
Step-by-step explanation:
We are trying to solve for x
7x-2z=4-xy
Add xy to both sides:
7x-2z+xy=-xy+4+xy= xy+7x-2z=4
Then you add 2z to both sides:
xy+7x-2z+2z=4+2z
xy+7x=2z+4
Then you factor out variable x
x(y+7)=2z+4
You divide both sides by y+7
x(y+7)/y+7= 2z+4/y+7
Which we would get x=2z+4/y+7
4/9 x 21/6 is this what you’re asking?
If so the answer is 1 5/9
Part A Answer: Company A: (Wx6)+12 Company B: (Wx5)+15
The varible used was W because windows start with a W i chose this as the variable because it is for the certain NUMBER of windows.
Part B:Company A: 8x6=48+12=$70 for 8 windows and service charges.
Company B:8x5=40+15=$55 for 8 windows and service charges.
Company B would charge less for 8 windows.
Part C:My work for Company A: 6x6=36+12=$48 for 6 windows and service charges
My work for Company B: 6x5=30+15=$45 for 6 windows + service charges
$48-$45=$3
Answer for Part C: $3 would be saved by using the services of Company B instead if Company A to clean 6 windows.
Interesting question. Good to know for computer science.
Suppose you have a function like
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1
a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3
an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3
a3 = 7
a4 = a3 + 3
a4 = 7 + 3
a4 = 10
a5 = a4+ 3
a5 = 10 + 3
a5 = 13
I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16
a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.
So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.
