In algebra, we often study relationships where a change to one variable causes change in another variable. Describe a situation

you’re familiar with where one quantity changes constantly in relation to another quantity. How are the two quantities in the situation related? If you represent the two quantities on a graph, what will it look like? 30 Response(s) New Response to Topic Profile Picture Isa Pollard - 9/20/2021 4:55 PM

a) situation you’re familiar with where one quantity changes constantly in relation to another quantity is Velocity  =  Distance/Time

b)  the velocity is in direct proportion to distance and inverse relation to time.

c) The graph shown by velocity- time is a straight line graph.

<h3>what is algebra?</h3>

Algebra is a branch of mathematics that deals with symbols or variables and uses arithmetic operations (+, –, ×, ÷) to find the unknown quantities represented by these variables.

There is a equation we are familiar with , the equation of motion

Velocity  =  Distance/Time

Here, velocity increases or decreases if the distance also increases or decreases. But if time increases velocity decreases.

So, the velocity is in direct proportion to distance and inverse relation to time.

The graph shown by velocity- time is a straight line graph.

Answer:

1. 2(x+2)(x+5)

2. 8(x+4)^{2}

Step-by-step explanation:

<u>Problem #1:</u>

1. Find the GCF (Greatest Common Factor)

GCF = 2

2. Factor out the GCF and simplify.

2(x^{2} +7x+10)

3. Factor x^{2} +7x+10

<u>Which two numbers add up to 7 and multiply to 10?</u>

2 and 5

<u>Rewrite the expression using the above.</u>

(x+2)(x+5)

4. Done!

2(x+2)(x+5)

<u>Problem #2:</u>

1. Find the GCF (Greatest Common Factor)

GCF=8

2. Factor out the GCF and simplify.

8(x^{2} +8x+16)

3. Use the perfect square formula. a^{2} +2ab+b^{2} =(a+b)^{2}

a = x\\b=4

(x+4)^{2}

4. Done!

8(x+4)^{2}

Evaluate the expression -8x + 5 - 2x - 4 + 5x when x = 2 before and after simplifying.
Alex777 [14]

Answer:

Step-by-step explanation:

all we have to do is plug in 2 for x into the equation:

-8(2) + 5 -2(2) -4 + 5(2)

-16 + 5 -4 -4 + 10

-11 -8 + 10

-19 + 10

the answer is

-9

to simplify the equation we’ll combine like terms

-8x + 5 -2x -4 + 5x

-10x + 1 + 5x

-5x + 1

now we’ll plug in 2 for x

-5(2) + 1

-10 + 1

the answer is still

-9

One eight of Tony's books are mystery books. He has 3 mystery books. How many books does tony have in all?
Leviafan [203]
Tony has 24 books in total because if 1/8 of the books are mystery and there are 8 mystery books you have to multiple the denominator by the amount of mystery books (8*3=24).
