Answer:
negative 1 over 27
Step-by-step explanation:
81 * negative 1 over 27 = -3
2x+y=-6 the equation has to be in slope form (y=mx+b) the first thing that you have to do is find the slope which you can do fairly easy by moving the 2x to the other side of the equation. Y=-2x-1 then you use that slope and use a different y intercept for the two lines to be parallel
Answer:
you use the foil method, which is just multiplying the first and second term in the first parentheses by the two numbers in the parentheses being multiplied.
Answer:
6
Step-by-step explanation:
3(x+2) = 4x
3x + 6 = 4x <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside
3x - 3x + 6 = 4x - 3x <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.
6 = x
Answer:
$5.46
