-x+5y=8 find the solution of the system of equations

Mathematics
1 answer:
nydimaria [60]2 years ago
5 0

Answer:

let me explain how you do this:

Step-by-step explanation:

first, you write your equation down:

-x + 5y = 8

next, group everything out seperately so you can know what to do in this problem, like grouping out each variable and number you see. then, figure out if the solution is simplified down to the last number. if so, if there is two variables that aren't the same, try and figure out a way to solve this equation with these two different variables. figure out if you have to multiply, subtract, add, or divide.

Use slopes and y-intercepts to determine if the lines 5x-5y=-2 and -x+2y=4
HACTEHA [7]

The given pair of lines are not perpendicular.

<h3>What is a line?</h3>

The line is a curve showing the shortest distance between 2 points.

5x - 5y = -2 - - - - - (1)
Transform the equation into standard form,
5x + 2 = 5y
y = 5x /5 + 2/5
y = x + 2/5


The slope of equation 1 is m_1 = 1  and intercept c = 2 / 5


Similarly
x + 2y = 4    - - - - - - - -(2)
Transform it into standard form
y = -x/2 + 4 /2
y = -x / 2 + 2


Slope of the equation 2  m_2= -1 / 2 and intercept c = 2
Slope of line 1 * slope of line 2 = 1 * -1/2 = -1/2


Since the lines are not perpendicular because the pair of lines does not satisfy the property of perpendicular lines i.e
m_1*m_2 = -1

Thus, the given pair of lines are not perpendicular.
