Y = 4+3x
2x+1 = y
Rewrite as two systems of equations.
3x - y = -4
2x - y = -1
Now use the substitution method to find the point of intersection.
You can also graph both equations on the same xy-plane using your graphing calculator to find the desired point.
Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
Answer:
3/4 hour
Step-by-step explanation:
1/3 + 1/6 + 1/4 = 4/12 + 2/12 + 3/12 = 9/12
12*5 = 60
9*5 = 45
45/60 = 3/4
Since both lines c and b are perpendicular to line a, line c and b are parallel.
Using the two points on line b, we can count “up 5, right 5” to find the slope of line b to be 5/5 or 1.
Since line b has a slope of 1 and line c is parallel, it must also have a slope of 1.
