The correct answers for x would be
.
In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following.
11
- 4x - 1 = 0
Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below.
Now we can plug the values into the equation to solve.
Then simplify using the order of operations.
.
Exponent rule : a^-b = 1 / a^b
52^-5 =
1 / 52^5 =
1 / (52 * 52 * 52 * 52 * 52)
So y=9....
9=-3x+6
3=-3x
x=-1
so answer.....-1,9.....that is C
Answer: 15, because it is 16-1
Answer:20
Step-by-step explanation:
25% is 1/4 so multiply 5 times 4
