Answer: (12,0)
Steps:
First, put the equation in slope-intercept form.
y=mx+b
1.5x + 4.5y =18
Subtract 1.5x from both sides.
4.5y =-1.5x +18
Divide both sides by 4.5 to isolate y.
y = -1/3x + 4
Then replace y with 0 because the point for the x-intercept is exactly on the x-axis so the y=0.
0 = -1/3x + 4
Subtract 4 from both sides
-4 = -1/3x
Divide both sides by -1/3 to isolate the x
12=x
Answer:
y
Step-by-step explanation:
that easy just isolate the variables
The sum of the interior angles in a regular polygon is given by the formula 180<span>(n – 2), where n is the number of sides in the polygon. An octagon has </span>eight<span> sides, so the sum of the angles of the octagon is </span>180<span>(8 – 2) = </span>180(6<span>) = 1080 degrees. In other word your answer would be an octagon.
