In this equation what do i have to change to make x equal 0 instead of 1/4
2√x+4-2=3

Answers

Answer 1
Answer: To solve for x:
- add 2 to both sides
2/x+4=5
- subtract 4 from both sides
2/x=1
- divide both sides by 2
/x= 1/2
- square both sides
x = 1/4

Y=AB-8. Trying to learn how to solve for A.

Answers

Answer:

A=(Y+8)/(B)

Step-by-step explanation:

So we have:

Y=AB-8\n

First, add 8 to both sides. The right will cancel:

Y+8=AB

Now, notice that A is multiplied to B. So, the isolate A, divide both sides by B. The right will cancel:

A=(Y+8)/(B)

And we're done!

What is the solution of the system of equations: -2x+8y=-8 and 5x-8y=20 using elimination​

Answers

Answer:

x = 4 and y = 0

Step-by-step explanation:

Given expression:

         -2x + 8y = -8

           5x - 8y = 20

Now, to solve this problem by elimination, follow this procedure:

           -2x + 8y = -8     --- i

            5x - 8y = 20      --- ii

 Coefficient of y in both expression have similar values;

  Now, add equation i and ii;

         (-2x + 5x) + (8y -8y ) = -8 + 20

                3x = 12

  Divide both sides by 3;

                 x = (12)/(3) = 4

Now, to find y; put x = 4 into equation i,

              -2(4) + 8y = -8

                -8 + 8y = -8

      Add +8 to both sides of the expression;

                -8 + 8 + 8y = -8 + 8

                              8y = 0

                                 y = 0

What is the inverse of f(x)=(2x+1)2 for x≥−12?

Answers

The inverse of the function will be f⁻¹(x) = [√(x) - 1] / 2 for x ≥ 0.

What is the inverse function?

Let the function f is given as

y = m(x + a) + c

Then the inverse function of the function f will be given by the swapping of x with y and y with x.

The quadratic function is given below.

f(x) = (2x + 1)²

Then the inverse of the quadratic function will be

x = (2f⁻¹(x) + 1)²

2f⁻¹(x) + 1 = √x

2f⁻¹(x) = √x - 1

f⁻¹(x) = [√(x) - 1] / 2 for x ≥ 0

The inverse of the function will be f⁻¹(x) = [√(x) - 1] / 2 for x ≥ 0.

More about the inverse function is given below.

What is the x-and y-intercept of the graph 4x -5y =40??

Answers

Answer:

x-intercept = 10

y-intercept = -8

Step-by-step explanation:

4x-5y=40

To identify the y-intercept, we will need to format the equation in the form y=mx+b. We can start by subtracting 4x from both sides of the equation:

-5y=-4x+40

Divide both sides of the equation by the coefficient of y, which is -5:

y=(-4)/(-5) x - 8

The b is representative of the y-intercept in y=mx+b.

Identify b in the equation y=(-4)/(-5) x - 8:

b=-8

Therefore, our y-intercept is -8.

To solve for the x-intercept, replace the y in the equation y=(-4)/(-5) x - 8 with a zero:

0=(-4)/(-5) x - 8

Add 8 to both sides of the equation:

8=(-4)/(-5) x

You can go ahead and divide -4 by -5 to get rid of the fraction:

8=0.8x

Divide both sides of the equation by the coefficient of x, which is 0.8:

10=x

Therefore, our x-intercept is 10.
