Answer:
Joey sold 6 cars
Step-by-step explanation:
Joey earns $350 per week + $200 per car he sells
The number of cars that he sold last week is unknown, so represent it with a variable, x.
Write an equation
$350 + $200x = $1,550
Subtract $350 from both sides of this equation
$200x = $1200
Divide both sides of the equation by 200
x = 6

Hope this helps :)

Step-by-step explanation:
Hi, there.
For this question, we can apply the Pythagorean theorem
.
I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.
Lengths a and b both have the value of 48, which means that the value s in
is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.
Plug in the value for c: ![a^2 + b^2 = (\sqrt{2s^2})^2](https://tex.z-dn.net/?f=a%5E2%20%2B%20b%5E2%20%3D%20%28%5Csqrt%7B2s%5E2%7D%29%5E2)
Plug in the value for s:
![(\sqrt{2(48^2)})^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B2%2848%5E2%29%7D%29%5E2)
Do the innermost exponents first:
![(\sqrt{2(2304)})^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B2%282304%29%7D%29%5E2)
The square root symbol and the power of 2 cancel each other out, so we are left with:
s =
, so the hypotenuse is 4608 inches.
Answer:
B. y + 2 = -2(x - 4)
Step-by-step explanation:
First, find the slope (m) of the line using two points in the line, (3, 0) and (4, -2):
![slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 - 0}{4 - 3} = \frac{-2}{1} = -2](https://tex.z-dn.net/?f=%20slope%20%28m%29%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%3D%20%5Cfrac%7B-2%20-%200%7D%7B4%20-%203%7D%20%3D%20%5Cfrac%7B-2%7D%7B1%7D%20%3D%20-2%20)
Slope (m) = -2.
Next, substitute (a, b) = (4, -2) and m = -2 into y - b = m(x - a)
Thus:
y - (-2) = -2(x - 4)
y + 2 = -2(x - 4)
