Write a relationship for a function whose k(x) values are 5 more than four times the principal square root of x .
bearhunter [10]

Answer:

k(x)=5+4\sqrt{x}

Step-by-step explanation:

Write a function whose k(x) values are 5 more than four times the principal square root of x.

So,

the principal square root of x =\sqrt{x};

four times the principal square root of x =4\sqrt{x};

5 more than four times the principal square root of x =5+4\sqrt{x};

Thus,

k(x)=5+4\sqrt{x}

Asha and Jamal are selling plants to raise money for their soccer team. They started out with 45 plants. They sold some plants a
sukhopar [10]
ANSWER

C. Both equations will find the correct solution.


EXPLANATION

It was given in the question that, Asha and Jamal started with 45 plants.


We were told that, they sold some plants and now they have 21 plants left.

Let
p
represent the number of plants sold.



Then when we add the number of plants sold and the number left, we should get 45.


This implies that,

21 + p = 45


This is Jamal's equation.


On the other hand, if we subtract the number of plants sold from the total number of plants, we should get 21. Thus,

45 - p = 21

This is Asha's equation.


The two equations are therefore equivalent.



They will give the same solution.


The correct answer is C.

3x − x − 1 = 15<br> What is x
azamat

Answer: x=8

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−x−1=15

3x+−x+−1=15

(3x+−x)+(−1)=15(Combine Like Terms)

2x+−1=15

2x−1=15

Step 2: Add 1 to both sides.

2x−1+1=15+1

2x=16

Step 3: Divide both sides by 2.

2x /2 = 16 /2

x=8
