Answer:
K/(4+9b) = a
Step-by-step explanation:
K = 4a + 9ab
Factor out a on the right hand side
K = a(4 + 9b)
Divide each side by (4+9b)
K/(4+9b) = a(4 + 9b)/(4+9b)
K/(4+9b) = a

Step-by-step explanation:
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

Answer:
x = 10
Step-by-step explanation:
Okay, let's solve :)
So first we have to distribute on the left side(it doesn't matter which side FYI)
When we do, we have :
10x + 30 = -4(-5-2x)
Now we distribute on the right side! Remember, negative * negative = positive.
10x + 30 = 20 + 8x + 3x
Let's simplify on the right side to
10x + 30 = 20 + 11x
Now, let's subtract 10x on both sides to get
x + 20 = 30(i simply flipped the equation)
Subtract 20 on both sides to get!
x = 10!
