Answer:
Step-by-step explanation:
In point slope form, the equation is y-7=(-10/3)(x+9). In slope-intercept form, it is y=(-10/3)x-23.
First find the slope of the line. The formula for slope is
m=(y₂-y₁)/(x₂-x₁)
Using our points, we have
m=(-3-7)/(-6--9) = -10/3
Plug this into point slope form:
y-y₁=m(x-x₁)
y-7=(-10/3)(x--9)
y-7=(-10/3)(x+9)
Using the distributive property:
y-7=(-10/3)*x+(-10/3)*9
y-7=(-10/3)x-90/3
y-7=(-10/3)x-30
Add 7 to both sides:
y=(-10/3)x-23
Answer:
It would take 5.5 months for the two cable companies to cost the same.
Step-by-step explanation:
50x + 100 = 60x + 45
-45 -45
50x + 55 = 60x
-50x -50x
55 = 10x
/10 /10
x = 5.5
Answer: D
Step-by-step explanation:
I got (-7,0) for the focus & Origin: (0,0)
Answer:
20mm
Since it a equilateral triangle we know that there is 3 sides and all of them are euqal. Therefore, 60/3 =20 meaning each side is 20mm.
