Answer:
<u><em>67</em></u>
Step-by-step explanation:
<u><em>50-40+87-30</em></u>
=50+(- 40)+87(-30)
=50+87+(-40)+(-30)
=(50+87+(-40)+(-30)
=137+(-70)
=67

Answer:
A. -10
Step-by-step explanation:
Hi there!
We are given that the equation of line m is , and we want to find the slope of the line perpendicular to m
Perpendicular lines have slopes that multiply to get the result of -1
So let's find the slope of line m
The equation is written in the form y=mx+b, where m is the slope, and b is the y intercept
As is in the place of where the slope should be, is the slope
Now find the slope of the perpendicular line with this formula:
In that case,
Multiply both sides by 10
So the slope of the perpendicular line is -10, or A
Hope this helps!
