Answer:
4/15
Step-by-step explanation:
2x/5-3y/2=7
<em>Multiply all terms by the lcd.</em>
10(2x/5) + 10(-3y/2) = 10(7)
<em>Cross cancel.</em>
2(2x)+ 5(-3y) =70
<em>Simplify.</em>
4x -15y = 70
<em>Subtract 4x from both sides.</em>
-15y = -4x +70
<em>Divide by -15 on both sides.</em>
y= 4/15x -24/3
Answer: ) The slope is equal to zero
2) The slope is undefined
Step-by-step explanation:
we know that
The lines that are parallel to the x-axis (horizontal line) have a slope equal to zero
The lines that are parallel to the y-axis (vertical line) have a slope undefined
so
The line
Is a vertical line -----> is parallel to the y-axis
The slope is undefined
Part 1)
The slope of a line that is perpendicular to it will be a horizontal line
so
the slope is equal to zero
Part 2)
The slope of a line parallel to it will be also a vertical line
so
the slope is undefined
The answer is going to be x=28
Here is how I did it:
You first need to subtract it first
6x/7+15-8=31
6x/7+7=31
you have to find the common denominator
6x/7+7=31
6x/7+7*7/7=31
Multiply all the terms by the same value to eliminate fraction denominators
7(6x+49)/7=7*31
6x+49=7*31
Multiply the numbers
6x+49=7*31
6x+49=217
Subtract 49 from both sides
6x+49=217
-49 -49
Now theres 6x=168
Divide both sides
6x=168

x=28 is your answer
Mark as brainiest
1) place the compass needle on the external point r.2) make the compass width greater than the distance from r to the given line.
3) draw an arc cutting the given line at two points.
4) mark and label the points of intersection p and q.
5) without changing the compass width, move the compass needle to q and draw another arc below the line crossing the previous arc.
6) move the compass needle to p and make an arc below the line.
7) mark and label the point of intersection s.
8) draw a line from the external point r to the point where the arcs intersect, s.
9) line rs is perpendicular to line pq and passes through the external point r.
