Hey there!

9 * 7 = x * 9

9 * 7 = 63

63 = x * 9

x * 9 = 63

9x = 63

Divide 9 to BOTH SIDES

9x/9 = 63/9

CANCEL out: 9/9 because that gives you 1

KEEP: 63/9 because it gives you the x-value

x = 63/9

63/9 = x

x = 7

9 * 7 = 7 * 9

The number that belongs in the blank (your answer) is: 7

Good luck on your assignment and enjoy your day!

PLEASE HELP! I AM REALLY CONFUSED! find the value of a if X^3+8x^2+ax-2 is divisible by x-1
WARRIOR [948]

The value of a from the equation is -63.

Here we have to find the value of a.

Given data:

The equation is = x³ + 8x² + ax -2

The equation is divisible by x -1

So we have:

x -1 = 0

x = 1

Now putting the value in the equation we get the remainder as o because the equation is divisible by x -1.

So;

1³ + 8² + a(1) - 2 = 0

63 + a = 0

a = -63

Therefore we get the value of a as -63.

To know more about the equation refer to the link given below:

How do you simplify 13=9y
Ratling [72]
The answer is y = 13/9 or y = 1.444.......
Either answer is correct!
Explanation:
Move the 9 to the other side of the equation, and divide it by 13, which will then get you to a decimal answer of y = 1.444.....
Or, if you don’t want a decimal answer, you don’t have to do the division, you can just leave your answer as y = 13/9
I’m so sorry if the explanation was confusing!
