Answer: A

Step-by-step explanation:

When you use the distributive property, you are multiplying every term in the parentheses by the number outside of it. You are typically multiplying so that is how you will get the simplified form of your equation.

In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving that lines

ohaa [14]

Answer:

See the proof.

Step-by-step explanation:

Statement   Reason

1.∠1 and ∠2 are supplementary angles --- Given

2. m∠1 + m∠2 = 180° --- Linear pair, they are supplementary

3. m∠1 and m∠3 are supplementary angles -- m∠1 + m∠3= 180

(Supplementary angles add upto 180 degrees)

4. m∠1 and m∠3 ------ Exterior sides in opposite rays

5. m∠1 + m∠2 = m∠1 + m∠3 ------ Transitive property

6. m∠2 = m∠3 -------------- Subtraction property

7. l || m ------------- If two lines are cut by transversal the alternative interior

angles are the same, then the lines are paralle.

Thank you.

Using the functions presented in the example, how much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

12345 [234]

Answer:

Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.

Step-by-step explanation:

Given : $C(a)=7500a-1500$ , $M(C)=0.9C- 50$ and $M(C(a))=6750a-1400$

To find : How much can Cam expect to earn if he sells all the corn produced on 1.5 acres?

Solution :

$C(a)=7500a-1500$

Substitute a=1.5,

$C(1.5)=7500(1.5)-1500$

$C(1.5)=11250-1500$

$C(1.5)=9750$

Now, taking function $M(C)=0.9C- 50$

Substitute C=9750,

$M(9750)=0.9(9750)- 50$

$M(9750)=8775- 50$

$M(9750)=8725$

Now, taking function $M(C(a))=6750a-1400$

Substitute a=1.5,

$M(C(1.5))=6750(1.5)-1400$

$M(C(1.5))=10125-1400$

$M(C(1.5))=8725$

Therefore, Cam expect to earn if he sells all the corn produced on 1.5 acres is $8725.
