Plug them into point-slope form.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Plug in what we know:
y - 4 = -5(x + 2)
So one of our answers is C.
Now distribute -5 into the parenthesis:
y - 4 = -5x - 10
Add 4 to both sides:
y = -5x - 6
Add 5x to both sides:
5x + y = -6
So the other answer is B.
117miles/180minutes ~~ 117miles/3hours ~~ miles/hour(mph)
117miles ÷ 3hours = 39miles/hour or 39 miles per hour.
(<em>Speed=x</em>) Speed needed is: x ≥ 39mph.

Answer:
36(5)^-2.
Step-by-step explanation:
5^-2 * 9
= 9(5)^-2
2^4 * 4 ^ -3
= 2^4 + (2^2)^-3
= 2^4 * 2^-6
= 2^-2
So the answer is
9(5^)-2 / 2^-2
= 9(5)^-2 * 2^2
= 4*9(5)^-2
= 36(5)^-2.
Yes, that is true, you have to simplify -42/-45 to be able to see if they are equivalant.
