Answer:

The change in x = Δx = -1

Step-by-step explanation:

Given the ordered pairs

(6, -3)

(5, 1)

Here,

x₁ = 6

x₂ = 5

y₁ = -3

y₂ = 1

Change in x can be calculated by subtracting the value of x₁ = 6 from x₂ = 5.

Change in x = Δx = x₂ - x₁ = 5 - 6 = -1

Thus, the change in x = Δx = -1

Mr. Hans wants to give an award to the student with the best jump rope rate. Linda can jump rope 120

Gelneren [198K]

Answer:

c) Mike receives the award for being the best at jumping rope.

Step-by-step explanation:

Here, according to the question

Jumping rate of Linda = 120 times in 4 minute

So, number of jumps Linda does per minute = (120/4) = 30

So, Jumps per minute of Linda is 30.

Jumping rate of Carl = 315 times in 9 minute

So, number of jumps Carl does per minute = (315/9) = 35

So, Jumps per minute of Carl is 35.

Jumping rate of Mike = 252 times in 7 minute

So, number of jumps Mike does per minute = (252/7) = 36

So, Jumps per minute of Linda is 36.

Now if we compare the <u>jumps per minute</u> of Linda , Carl and Mike, weget that Mike has the best rate of 36 jumps per minute.

Hence, Mike receives the award for being the best at jumping rope.

The graph of y = f(x) is shown below. Determine the value of x when f(x) = -4? ? y 10 9 8 7 6 5 ur 4 3 NO C 2 1 X -10 -9 -8 -7 -

Brilliant_brown [7]

Answer:

Step-by-step explanation:

the function f(x) is a straight line. The "-4" means that the graph moves down 4 units. Point A is at y=-4, so this is the point. You can graph the equation and you'll see that it hits point A.

I can't figure this one out please help!

Answer:

Step-by-step explanation:

The first answer is that the sale price is 25% cheaper its a dumb question.

The second answer is the 2nd option because it states that sale prices are 30% of the original. For example if you had a $100 item it would cost you 30% of that original price. But if you went to the first store it would cost you $70 dollars because its 30% off of the original price.

An offshore lighthouse is 2 kilometers from a Coast Guard station C and 2.5 kilometers from a hospital H near the shoreline. If

dangina [55]

Answer:

4.3 km

Step-by-step explanation:

The law of cosines can be used to find the desired distance. If we call the lighthouse position point L, then we have ...

CH² = LC² +LH² -2·LC·LH·cos(L)

CH² = 2² +2.5² -2·2·2.5·cos(143°) = 10.25 -10cos(143°) ≈ 18.2364

CH ≈ √18.2364 ≈ 4.27 . . . . km

The distance CH is about 4.3 km.
