Answer:
![g(2)=5](https://tex.z-dn.net/?f=g%282%29%3D5)
Step-by-step explanation:
since g(x) is equal to
, you just plug in the value of 2 for x, to get
, and 2 to the power of 2 (also known as 2 squared) is equal to 4, which makes your equation
, which equals 5.

Answer:
y = - 7
Step-by-step explanation:
The equation of a horizontal line is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (5, - 7) with y- coordinate - 7, thus
y = - 7 ← equation of horizontal line
when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one. Check the picture below.
