Find the slope of the line through p and q. p(1, −9), q(−3, 2)

1 answer:

7 0

To find the slope,we can use the point-slope form:
$y1 - y2 = m(x1 - x2)$
Where m is the slope.

In this case,the equation would be:
-9-2 = m(1-(-3))
-11 = m(1+3)
-11 = 4m
m = -11/4

Therefore the slope is -11/4.

Hope it helps!

Oliver and Lenny started hiking a hill simultaneously from the bottom to the top. Oliver hiked at a speed of 5 km/h during the f

Papessa [141]

Answer:

Oliver and Lenny reached the top of the hill at the same time

The proportion of time Oliver spent hiking to that of Lenny is 1:1

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Oliver's speed = 5 km/h during the first half, then decreased his speed to 4 km/h during the second half.

Lenny's speed = 4 km/h during the first half, then increased his speed to 5 km/h in the second half.

2. Who reached the top of the hill first? What is the proportion of time he spent hiking to that of his friend?

Let's assume the distance from the bottom to the top of the hill is 10 kilometers for calculating the time it will take Oliver and Lenny to reach the top of the hill:

Speed = Distance/Time

Time = Distance/Speed

Oliver = Time of hiking first 5 km + Time of hiking second 5 km

Lenny = Time of hiking first 5 km + Time of hiking second 5 km

Oliver = 5/5 + 5/4

Oliver = 1 + 5/4 = 2 1/4 hours

Lenny = 5/4 + 5/5

Lenny = 5/4 + 1 = 2 1/4 hours

Oliver and Lenny reached the top of the hill at the same time

The proportion of time Oliver spent hiking to that of Lenny is 1:1

PLZ HELP AND EXPLAIN THIS PLZ

AURORKA [14]

Answer:

A. 4 trucks will make $80 because 4 × 20 = 80, so they need to wash 38 cars to make the other $380 because 38 × 10 = 380.

($80 + $380 = $460)

B. 15 trucks will make $300 because

15 × 20 = 300, so they need to wash 16 cars to make the other $160 because 16 × 10 = 160. ($300 + $160 = $460)

C. 21 trucks will make $420 because

21 × 20 = 420, so they need to wash 4 cars to make the other $40 because 4 × 10 = 40.

($420 + $40 = $460)

D. 27 trucks will make $540, so they won't have to wash any cars because they would have already exceeded their goal of $460.

Not sure what to do for letter E. Sorry. I hope the rest makes sense though :)
