Which are the solutions of x2 = –5x + 8?

x=1.53

x=6.53

Step-by-step explanation:

The first thing to do is to leave the equation equal to zero expressed.

Next, being a second degree equation, we can use the general formula to find the solutions. This equation is as follows:

Where a is the coefficient of the quadratic term, b the coefficient of the linear term and c the coefficient of the value without variable.

In this case:  a=1, b=5, c=-8

Replacing in the ecuation

Now

So, both solution:

x=1.53

x=6.53

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
