15 POINTS!!! How do the rules for adding and subtracting signed decimals compare with the rules for adding and subtracting integ
MArishka [77]

Answer:

The rules for adding and subtracting signed decimals are almost the same as the rules for adding and subtracting integers. When dealing with decimals, you need to be especially aware that your decimal points are lined up so that you do not accidentally add or subtract in the wrong place.

Perpendicular to y=-3x+11 and goes through the point (-9,-6)<br> please help it’s due next period
mafiozo [28]

Answer:

y = 1/3x - 3

Step-by-step explanation:

If the line is perpendicular to y = -3x + 11, it means that the two gradients multiply to make -1.

So the gradient of the perpendicular line is 1/3 (-3 × 1/3 = -1)

y = 1/3x + c

Next, substitute x = -9, and y = -6 to find the y intercept, or c:

-6 = 1/3(-9) + c

-6 = -3 + c

c = -6 + 3

c = -3

The equation of the line is y = 1/3x - 3
