In order to find what x equals, we need to make it so x is on one side and what it equals, on the other.
First of all, we subtract 10 from both sides. You will now have:
x^3 - 5x^2 + 2x - 10 = 0
You will now either factor it which is recommended or use the Cubic Formula which is pretty difficult to memorize and to solve. I will now factor it.
( x - 5) ( x^2 + 2 ) = 0
You can now take both of the expressions inside and make them equal to zero and solve them.
x - 5 = 0x = 5
x^2 + 2 = 0x^2 = -2
x <span>≈</span> 1.41421356i
The second option is irrational and uses an imaginary number which you will start seeing in Alegbra II (or already have if you are taking it or have already passed it), so the first one which is 5, is the correct answer.
Answer: 5
hello :<span>
<span>the parabola's equation is : f(x) = a(x-5)²-5
the coefficient of the squared expression in the parabola's equation is : a
but ; f(6) = - 1
- 1 = a(6-5)²+5
a+5=-1.....a=-6
f(x) = -6(x-5)²+5</span></span>
<span><span>so : a = - 6</span></span>

Desirre's 15 problem: 15 * 20% = 3 word problem
Answer:
72xy1
Step-by-step explanation:
becuz the multiple of 9,6 and 24 is 72 and the multiple of x is 1x which is just x and the multiple of y is 1y
Without further information, you can't deduce the length of one side of a triangle knowing the other two.
You can only use the inequalities that tell you that the sum of two sides is greater than the remaining one to get
which is true for all positive x values
So, knowing only the length of two of the sides, we can only say that the third side is between 3 and 35 inches long.
