Answer:
m<4 = 117 degrees
Step-by-step explanation:
Knowing that angle 1 is 63 degrees, we can look at the other angle on the same side of the line, angle 4.
Angles on one side of a line add to 180 degrees.
180 - 63 = 117

Answer:
The parabola will reflect over the x axis.
Step-by-step explanation:
By setting the "a" value to a negative number, you will be inverting the f(x) values, in other words making a parabola open downwards, or a direct reflection over the x axis of the parent formula.
Take f(x)=1x^{2}+0 for example.
if we plug in 1 for x f(x) will equal 1
however if we make the a value negative
f(x)= -1x^{2}+0
and set x equal to 1,
you should see that f(x) is now -1
