Step-by-step explanation:
Given expression;
2x + y = -5;
The given equation must be written in a form where the slope is the negative inverse of the given one.
A line perpendicular to another will have a negative inverse slope.
2x + y = -5
Equation of a straight line is generally written as;
y = mx + c
y and x are the coordinates
m is the slope
c is y - intercept
2x + y = -5
y = -2x -5
The slope of the perpendicular =
So,
the new line;
y = x -5
Any line with slope of will be perpendicular
Answer:
Let's start by breaking down the problem.
This is how it should look. ↓

What does that <em>x</em> mean? <em>x</em> is just a substituted value for the first 2 equations.
Now, we can solve.
÷
Add 3
Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.
And now for the last step, multiply 25 times 6
With that information, the problem is solved! Your answer is 150
