Answer:
The equation of the line is;
y = 3x + 18
Step-by-step explanation:
We want to write the equation of the line through (-9,-9) and (-6,0)
we start by calculating the slope of the line
m = (y2-y1)/(x2-x1) = (0+ 9)/(-6+9) = 9/3 = 3
The general equation of the line is;
y = mx + c
y = 3x + c
To get c, we use any of the points
we substitute for example -6 for x and 0 for y
0 = 3(-6) + c
c = 0 + 18 = 18
So the equation of the line is;
y = 3x + 18
Answer:
5.88
Step-by-step explanation:
5+4=9
53 divided by 9=5.88
Answer:
120º
Step-by-step explanation:
First we need to know the fraction of the area of ORT to the area of the circle.
Fraction = 18π/54π = 1/3
We know that a circle is 360º, and sector ORT is xº. The fraction of the sector of ORT to the circle must also be equal to 1/3.
x/360 = 1/3
3x = 360
x = 120º
I think that she wouldn't end up with “$14,400” she would end up with $76,800 if you multiply.
