If you would like to write the polynomial in standard form, you can do this like this:

4m - 2m^4 - 6m^2 + 9

Writing the polynomial in standard form<span> means that you have to </span>write<span> the terms by descending degree:
</span>- 2m^4 - 6m^2 + 4m + 9

The correct result would be <span>- 2m^4 - 6m^2 + 4m + 9.</span>

Solve the simultaneous equations: <br> 5x + 2y = 17<br> 4x + y = 10
erik [133]

Answer:

(1, 6 )

Step-by-step explanation:

5x + 2y = 17 → (1)

4x + y = 10 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the y- term

- 8x - 2y = - 20 → (3)

Add (1) and (3) term by term to eliminate y

- 3x + 0 = - 3

- 3x = - 3 ( divide both sides by - 3 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for x

Substituting into (1)

5(1) + 2y = 17

5 + 2y = 17 ( subtract 5 from both sides )

2y = 12 ( divide both sides by 2 )

y = 6

solution is (1, 6 )

Sam has traveled 33 miles and knows that 55% of his trip is complete.How many total miles is Sam's trip?
ahrayia [7]
60 miles in total.
to find percentages, you divide the part by the whole, so 33/60 = .55, which you then move the decimal over two places and read as a percentage

Step-by-step explanation:

<u><em>The complete question is</em></u>

As a part of its diet, a Pacific seahorse eats about 56 shrimp per week. It eats  the same amount each day.

a) How much shrimp does the Pacific seahorse eat per day?

Complete the statement with the unit rate.

The Pacific seahorse eats  _____ shrimp per day.

Part a) How much shrimp does the Pacific seahorse eat per day?

Let

x ---> the number of shrimp that the Pacific seahorse eats per day

we know that

The number of shrimp that the Pacific seahorse eats per day, multiplied by the number of days in a week, must be equal to 56 shrimp

1\ week=7\ days

so

The linear equation that represent this situation is equal to

7x=56

solve for x

Divide by 7 both sides

x=8\ shrimp

therefore

The Pacific seahorse eats  8 shrimp per day
