Answer:
hope this helps !
Step-by-step explanation:
1) ( 8 x- 16 ) / (x²- 13 x + 22 ) = ( 8 x- 16 ) ( x - 11) ( x -2 ) = 8 ( x-2) ( x-11) ( x- 2 ) = 8/(x-11)
Restriction x ≠ 11 & x ≠ 2
since both values render the denominator = to 0 & we can't divide by 0.
Find the perimeter of the rectangle with points...
W(6,9), X(9,7), Y(3,-2), Z(0,0)
Answer:
Exact Form:
x=−107
Decimal Form:
x=−1.428571
Mixed Number Form:
x=−137
Step-by-step explanation:
We can write two equations for this. x = each minute of calls
Plan A = .1x + 16
Plan B = .14x
Make the two equations equal each other, so we can find when they are the same.
.1x + 16 = .14x
Subtract .1x from both sides
16 = 0.04x
Divide by 0.04 to get x by itself
400 = x.
Earlier, we set x as each minute of calls. This means that after 400 calls, Plan A and Plan B will cost the same.
To find the cost, substitute 400 into both equations by themselves.
Plan A cost = .1x + 16
Plan A cost = .1(400) + 16
Plan A cost = 40 + 16
Plan A cost = $56
Plan B cost = .14x
Plan B cost = .14(400)
Plan B cost = $56
Final answer: After 400 calls, Plan A and Plan B will both cost $56.
