1. P = IRT....for T
P / (IR) = T
2. A = 2(L + W)....for W
A/2 = L + W
(A/2) - L = W
3. y = 5x - 6...for x
y + 6 = 5x
1/5y + 6/5 = x....or (y + 6)/5 = x
4. 2x - 3y = 8....for y
-3y = -2x + 8
y = 2/3x - 8/3
5. not exactly sure of the equation here.....(x + y) / 3 = 5 ?? or 3(x + y) = 5 ??
6. y = mx + b....for b
y - mx = b
7. ax + by = c....for y
by = c - ax
y = (c - ax)/b...or y = (c/b) - (ax/b)
Answer:
The 12 students can be lined up in 12! ways.
Put in dividers after every fourth student.
For example:
Given ABCDEFGHIJKL, we would put in dividers to get ABCD|EFGH|IJKL.
We have overcounted, though, in two different ways. Let's examine the resulting problems.
One problem is with regard to the three separate groupings appearing multiple times. In the example above, we would be counting EFGH|ABCD|IJKL a second time. Since there are three groups, we need to divide by 3! to avoid this sort of overcounting.
The second problem is that, within each of the three groups, we have four people who are going to appear multiple times. In the example above, we would be counting CDAB|EFGH|IJKL a second time. For each of the groupings, we need to divide by 4! to avoid this sort of overcounting. This means dividing by 4!4!4! to amelioriate the second issue.
Then our answer becomes:
12!3!4!4!4!=5,775

hope it help brainliest pls
Answer:
2
Step-by-step explanation:
Subtract the number with the term both sides ( which is 9)
Complete the square for the x terms and y terms.
( To complete the square divide the coefficient term by 2 and square it, then add that product to both sides.)
Take the square root of the right side to find the radius
Answer:
j<-1
Step-by-step explanation:
10j<-10
divide both sides by 10 and get
j<-1
