Answer:
10 hours and 20 minutes
Step-by-step explanation:
3am to 4am is 20 minutes
4am to 2pm is 10 hours
Move the 1st equation to get y by itself so it’s now y=-4x so you can substitute that in for the second equation 2y+x=-7 becomes 2(-4x)+x=-7
-8x+x=-7
-7x=-7
x=1
then plug that back in to find y
4(1)+y=0
4+y=0
y=-4
now you have x and y so your coordinate (the answer) is (1, -4) hope this helps!
42-x=58
or, -x=58-42
with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.
or, -x= 16
or,x=-16.
therefore x=-16...
<em>Hope</em><em> </em><em>this</em><em> </em><em>helps</em><em> </em><em>you</em><em>.</em>
Because n is a variable and a variable is serving that you can always change.
The slope of the line is 3/4 and the line is from the point (0, 2)
Equation of a line
A line is defined as the shortest distance between two points. The standard equation of a line is given as y = mx + b
where
m is the slope
b is the y-intercept
Given the equation y = -5/4 x
From the given equation, the slope of the line is 3/4 and the line is from the point (0, 2) as shown.
