Answer:
5
Step-by-step explanation:
Standard form: Ax+By=C
first put in slope-intercept form:
slope = (0+5)/(6-3) = 5/3
pick point D: 0 = 5/3(6)+b -> b= -10
slope-intercept form: y=(5/3)x-10
multiply both sides by 3:
3y=5x-30
put in standard form:
5x-3y=30
Answer:
Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.
Since after 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air, while after 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air, to determine who was descending at a faster average rate and what is Mel's rate of change, the following calculations must be performed:
You must subtract the difference between the two times for each person, and check which is the highest rate between the two.
Mel =
(50 - 35) / (5 - 2) = X
15/3 = X
5 = X
Victor =
(60 - 50) / (4 - 1) = X
10/3 = X
3.33 = X
Therefore, Mel was descending at 5 feet per second and Victor was descending at 3.33 feet per second, thus Mel was descending faster.
Answer:
10/8 or 1 1/5
Step-by-step explanation:
1) distributive property
- 6(x+2)+7=5(x+3)-7(x-2)
- 6x+12+7=5x+15-7x+14
2) combine like terms
3) isolate x
4)simplify
