Add 4 to both sides. Y+4=12x divide both sides by 12 y+4 over 12 which = x switch sides x= y+4 over 12 that’s the answer and I’m 100% sure

Use the midpoint formula to find the midpoint between H(3, 9) and J(9, -2).

TiliK225 [7]

Hello!

The midpoint formula is basically an average of x and y.

It is also written as: $(\frac{x_{1}+x_{2}} {2},\frac{y_{1}+ y_{2}} {2})$ .

With the formula above, we can substitute the given points into the equation, and simplify.

$(\frac{3 +9}{2}, \frac{9+(-2)}{2}) = (\frac{12}{2}, \frac{7}{2}) = (6, 3.5)$

Therefore, the midpoint between points H and J is choice D, (6, 3.5).

How many solutions does the system formed by x - y = 3 and ay + 3a = 0 have for a non zero number a? Explain and show how you ge

dlinn [17]

Solve both equations for y:
$x-y=3 \ \ \ |-x \\
-y=-x+3 \ \ \ |\times (-1) \\
y=x-3 \\ \\
ay+3a=0 \ \ \ |-3a \\
ay=-3a \ \ \ |\div a, a \not= 0 \\
y=-3$

Set the expressions equal to each other:
$y=y \\ x-3=-3 \ \ \ |+3 \\
x=0 \\ \\
(x,y)=(0,-3)$

So, for every nonzero number a the system of equations has one solution.
