Answer:
B
Step-by-step explanation:
180-130=50
180-50=130
130:2=65
Line l and line m intersect
2 is supplementary to 3
Angle 1 congruent to angle 3
Hope this helped :)
2n=14 n being the “number” divide 2 on both sides and you’re left w n=14/2 or7
Y = (-1/9).x + 4
The slope m of the line perpendicular to y = (-1/9).x + 4 is equal to 9:
(if the product of 2 slopes = - 1, then the 2 lines are perpendicular)
y = 9x + b, Since it passes by the point (-1,0) , then:
0= 9(-1) + b and b = 9
Final equation:
y = 9x+9
Answer:
4.5 mph or 9/2 mph
Step-by-step explanation:
Let x be the rate of the current
Formula: Distance = rate x time
where rate upstream =(12-x) and time =2 hours
15=(12-x)(2)
15=24–2x
2x=24–15
2x= 9
x=9/2=4.5 miles per hour (rate of current)
