What’s the inverse equation? And how you solved it step by step please!
Korvikt [17]

Answer:

The inverse is (x^2-5)/2

Step-by-step explanation:

y =sqrt(2x+5)

Exchange x and y

x = sqrt(2y+5)

Solve for y

Square each side

x^2 = (sqrt(2y+5))^2

x^2 = 2y+5

Subtract 5 from each side

x^2 -5 = 2y-5+5

x^2 -5 = 2y

Divide each side by 2

(x^2-5)/2 = 2y/2

(x^2-5)/2 = y

The inverse is (x^2-5)/2

What choices are solutions for equation x^2-3x = -5/4
Kryger [21]

Here's the solution,

=》

{x}^{2}  - 3x =  -  \dfrac{5}{4}

=》

{x}^{2}  - 3x +  \dfrac{5}{4}  = 0

now, let's multiply the whole equation with 4

=》

4 {x}^{2}  - 12x + 5 = 0

=》

4 {x}^{2}  - 10x - 2x + 5= 0

=》

2x(2x - 5) - 1(2x - 5) = 0

=》

(2x - 1)(2x - 5) = 0

so,

Case 1. where, 2x - 5 = 0

=》

x =  \dfrac{5}{2}

case 2. where, 2x - 1 = 0

=》

x =  \dfrac{1}{2}

A pair of runners leaves the same starting point at the same time. The angle between the runners paths is 85 degrees. They stop
goldfiish [28.3K]

Answer:

136.34 m  to the nearest hundredth.

Step-by-step explanation:

The runners paths and the distance between them after 30 second form  a triangle.

The side opposite the 85 degree angle is 180 m and one of the other sides is 130 m.

We need to find the third side.

We can use the Cosine Rule to do this:

If the third side is x m then:

180^2 = 130^2 + x^2 - 2*130x cos 85

180^2 = 130^2 + x^2 - 260 * x * 0.08716

180^2 = 130^2 + x^2 - 22.6616 x

x^2 - 22.6616 x - 15500 = 0

x =  [22.6616 +/- sqrt ((-22.6616)^2 - 4 * -15500) ]  / 2

x= 136.34 m.
