Answer:
105km
Step-by-step explanation:
1/7=15/x
So x=7*15
x=105
X-intercept is 0
Y-intercept is —4
The equivalent expression is 10x+5y-15z
Answer:
73/39
Step-by-step explanation:
The slope of the given line is the coefficient of x in the given equation, which we recognize as being in slope-intercept form.
The slope of the perpendicular line will be the opposite reciprocal of this:
-1/(-39/73) = 73/39 . . . . slope of the perpendicular line
