Evaluate -a - 12a 2 for a = -1

Mathematics
1 answer:
Serhud [2]3 years ago
6 0
The answer is -11
You put "-1" in place of all the "a"s and get 
-(-1) - 12(-1)^2
-(-1) is just 1, and (-1)^2 is "1"
We are then left with 1-12(1) which is 1-12 which is -11

Answer:

Step-by-step explanation:

Perpendicular lines are lines whose slopes are negative reciprocals of each other

To find the slope of the line we are given, we can rearrange the equation

4x - 5y = 4\\4x - 4 = 5y\\y = \frac{4}{5}(x) - \frac{4}{5}

The slope of this line is \frac{4}{5}, so the slope of the other line is \frac{-5}{4}

next, we can use the given point to find the equation y = mx +b

we know m, we can solve for b

y = \frac{-5}{4}(x) + b\\-3 = \frac{-5}{4}(-2) + b\\-3 = \frac{5}{2} + b\\\frac{-6}{2} = \frac{5}{2} + b\\

b = \frac{-11}{2}

so,\\y = \frac{-5}{4}(x) - \frac{11}{2}
