Solve the following equation. 2x - 1 ≤ x 5

1 answer:

5 0

2x−1≤x5

Let's find the critical points of the inequality.

2x−1=x^5

2x−1−x^5=x^5−x^5 (Subtract x^5 from both sides)

−x^5+2x−1=0

(−x+1)(x^4+x^3+x^2+x−1)=0 (Factor left side of equation)

−x+1=0 or x^4+x^3+x^2+x−1=0 (Set factors equal to 0)

x=1 or x=0.51879 or x=−1.290649

A triangle has 2 sides that are 9 inches and the bottom is 6 inches what is the height?

Elanso [62]

The height of the isosceles triangle is 8.49 inches.

<h3>How to find the height of the triangle?</h3>

Here we have a triangle such that two of the sides measure 9 inches, and the base measures 6 inches.

So this is an isosceles triangle.

We can divide the isosceles triangle into two smaller right triangles, such that the side that measures 9 inches is the hypotenuse, the base is 3 inches, and the height of the isosceles triangle is the other cathetus.

By Pythagorean's theorem, we can write:

(9in)^2 = (3 in)^2 + h^2

Where h is the height that we are trying to find.

Solving that for h we get:

h = √( (9 in)^2 - (3in)^2) = 8.49 inches.

We conclude that the height of the isosceles triangle is 8.49 inches.

Solve the equation. 8 -(x + 5) = 5x - 3

Mandarinka [93]

Answer:

x = 1

Step-by-step explanation:

8 -(x+5) = 5x - 3

-(x+5) ---> -1 (x +5) = -x - 5

8 - x - 5 = 5x -3 8 - 5 = 3

-x + 3 = 5x - 3

+x +x

3 = 6x - 3

+3 +3

6 = 6x

/6 /6

x = 1
