Rewriting the equation in the form (x+c)²=d by completing the square

The solutions to the quadratic equation are:

Step-by-step explanation:

Given the equation

subtract 22 from both sides

simplify

Rewriting the equation in the form (x+c)²=d by completing the square

solve

also solving

Therefore, the solutions to the quadratic equation are:

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 : )

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
