Answer:
The solutions are
and 
Step-by-step explanation:
we have

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side.


Rewrite as perfect squares


square root both sides

Answer:
Step-by-step explanation:
it is hard to know exactly by eye balling the graph I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it
the dots on the line are at (-2, -6) and (2, 3) so we can find the slope m
in the y = mx + b line equation b is the y intercept
m = Δy/Δx = (y1 - y2) / (x1 - x2)
= (-6 - -3) / (-2 - 2)
= -3 / -4
m = 3/4
y = 3x/4 + y intercept which i can't dissern (read directly from the
graph, but we believe y = 0 when x is six
0 = 3(6)/4 + y intercept
-18/4 = 18/4 -18/4 + y intercept
-9/2 = y intercept
-4.5 = y intercept
y = 3x/4 - 9/2 i think exact number means NO FRACTIONS but that is whole number so let me gaggle it What are exact numbers? Gaggle indicates exact numbers are integers example 3 ft in a yard 12 eggs in a dozen
y = 3x/4 - 9/2 multiple both sides by 4
4y = 3x - 36/2
4y = 3x - 18 <------------------ FINAL ANSWER
