Answer:

D is the correct answer

Step-by-step explanation:

Since 5x and 4x+1 are both equal to y, we can set them equal to each other as shown below:

5x=4x+1

x=1

Plugging x=1 into y=5x gets us y=5(1)=5

So x=1 and y=5, which is also (1,5)

Hope this helped!

Hey there! :)

Answer:

First option: As x⇒ ∞ f(x) ⇒ -∞. As x⇒ -∞ f(x) ⇒ ∞.

Step-by-step explanation:

Rearrange the equation:

f(x) = -x³ - 2x² + 1

This is a negative cubic function. The function decreases over the interval

(-∞, ∞). Therefore:

As x⇒ ∞ f(x) ⇒ -∞.

As x⇒ -∞ f(x) ⇒ ∞.

This is the first option.

Billy has 2.4 m of ribbon for crafts. He wants to share it evenly with 12 friends. Billy has been making craft projects for seve

Triss [41]

Answer:

140 cm

Step-by-step explanation:

Given that:

Total length of ribbon present with Billy = 2.4 m

This ribbon is to be shared with 12 friends evenly.

Billy is doing this work of making craft for the past many years.

To find:

How many centimeters of ribbon that 7 friends will get?

Solution:

First of all, let us find out what length of ribbon will each person get.

Length of ribbon to be shared with each person = Total length of ribbon divided by total number of persons

Length of ribbon to be shared with each person = $\frac{2.4}{12} = 0.2\ m$

Now, The length of ribbon that 7 friends will get = 7 $\times$ 0.2 = 1.4 m

1 m = 100 cm

1.4 m = 1.4 $\times$ 100 cm = <em>140 cm</em>
