You would have to plug it in ~ 5(3y-7)+2y=33, then you would multiply ~ 15y-35+2y=33, then you would simplify ~ 17y=68, then divide ~ y=4, then plug in y and multiply and simplify ~ x=3(4)-7 -- x=12-7 -- x=5. Answer~X=5 Y=4
X-7>10
add 7 to both sides
x=17
65g=0.065kg
0.065x100= 6.5kg of peaches
6.5x6= $39
Given:
Line
To find:
Slope of the perpendicular line and slope of the parallel line.
Solution:
Equation of a given line:
Subtract 8x on both sides, we get
Divide by -6 on both sides.
Slope of this line is .
If two lines are perpendicular then their slopes are negative inverse of one another.
Slope of perpendicular line =
If two lines are parallel, then their slopes are equal.
Slope of perpendicular line =
