Answer:
X+8y=3, 2x-4y=-14
Step-by-step explanation:
Since we do not know the values of x or y we have to leave them the way they are because you can't combine x and y
Answer:
-3
Step-by-step explanation:
:)
Answer:
3y-7
Step-by-step explanation:
-4y + 7y - 10 + 3
Combine like terms
-4y + 7y - 10 + 3
3y -7
Answer:
<h3>The answer is option C</h3>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question
y = - 1/2x + 5
Comparing with the general equation above
Slope / m = -1/2
Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line
That's
Slope of the perpendicular line = 2
Equation of the line using point (–1, –2) and slope 2 is
y + 2 = 2( x + 1)
y + 2 = 2x + 2
y = 2x + 2 - 2
We have the final answer as
<h3>y = 2x</h3>
Hope this helps you
