Solve using substitutionx=-6x-y=-8​

Mathematics
1 answer:
aleksklad [387]3 years ago
4 0

Answer:

(-6,2)

Step-by-step explanation:

x =  - 6 \\ x - y =  - 8

<u>Substitution</u>

Substitute x = -6 from the first equation in the second equation.

- 6 - y =  - 8 \\  - 6  + 8 = y \\ 2 = y

Normally, we have to substitute either x-term or y-term in one of the equation to get another term. For this situation, we already know the value of x so It is not necessary to substitute the y-value.

<u>Answer</u><u> </u><u>Check</u>

We have to check the answer to make sure that we have got the right answer.

We can check the answer by substituting both x-value and y-value in the equation.

x - y =  - 8

Substitute x = -6 and y = 2 in the equation.

- 6 -  2 =  - 8 \\  - 8 =  - 8

The equation is true. Therefore, our answer is (-6,2)

What is the difference of the fractions? Use the number line to help find the answer
alisha [4.7K]

Answer:

-7/10

Explanation:

Given the expression

\frac{1}{2}-1\frac{1}{5}

We can rewrite the expression as:

\frac{1}{2}-\frac{6}{5}=\frac{5}{10}-\frac{12}{10}

The number line showing the location of the two numbers is attached below. Therefore:

\frac{5}{10}-\frac{12}{10}=-\frac{7}{10}

The Parry Glitter Company recently loaned $300,000 to FIX 92, a local radio station. The radio station signed a noninterest-bear
melomori [17]

Answer:

The Parry Glitter Company

The Parry Glitter Company should record the Notes Receivable as $300,000.

It should also record the interest receivable per year as $24,000 and the advertising cost as $24,000 per year.  These bring into the accounting records the interest revenue and also the advertising expense, which eventually cancel each other.

Step-by-step explanation:

a) Data and Calculations:

Notes Receivable = $300,000

If the notes receivable are repaid at the end of 3 years and it is assumed that the interest on the notes receivable = 8%

Therefore, the cost of the free advertising will be equal to $24,000 ($300,000 * 8%), which is the cost of the interest to the radio station.

Micah walks on a treadmill at 4 miles per hour. He has walked 2 miles
lana66690 [7]
<span>Let time taken by Luke to cover the distance = x hours Speed of Luke = 6 miles per hour Therefore, Distance covered by Luke = 6x ------(1) Speed of Micah = 4 miles per hour Since Micah walked 2 miles before Luke started running, Luke started 1/2 an hour after Micah started. Therefore time taken by Micah to cover the distance = x+1/2 Distance covered by Micah = 4(x + 1/2) -------(2) Equating (1) and (2) 6x = 4(x+1/2) 6x = 4x +2 2x = 2 x= 1 Therefore Luke would take 1 hour to cover the distance covered by Micah.</span>
