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:
We have, 63% × x = 252
or,
63/100 × x = 252
Multiplying both sides by 100 and dividing both sides by 63,
we have
x = 400
