The error was in second step.
3√(y^3)^4 = y^4
(Cube root cancels cube and not power 4)
The answer should be:
xy^4/4
//Hope it helps.
Answer:
x = -1/4
Step-by-step explanation:
3/x = -4 - 8
3/x = -12
x= -3/12
x= -1/4

33) When adding matrices, just add the numbers that are in the same spot. In this problem we are given A and C, and we are asked to find B if A + B = C
So B = C - A

34) When multiplying matrices, the number of columns in the first matrix needs to be the same as the number of rows in the second matrix. Then the outcome will have the same number of rows as the first matrix and same number of columns as the second matrix. In this case, the result will be a 2x2.
C because K is 1,-8 so if you go up 1, -7, and right 4,5. So you get k(5,-7)
Answer:
$14.70
Step-by-step explanation:
If she get paid the time and a half you would first divide $9.80 by 2 which is $4.90. Now that you have the half price you add the original time to it. $9.80+$4.90= 14.70 so that’s the answer
