Find the x-value and the y-value of the solution to this system of equations:

Mathematics

Serjik [45]3 years ago

Answer:

The solution is (-6, 30)

Step-by-step explanation:

Here we have two separate equations for y and are to find the solution (x, y).

y = 2x + 42

y = -5x

First, equate y = 2x + 42  and y = -5x:

2x + 42  = -5x

Combining like terms, we get

7x = -42, which results in x = -6

Since y = -5x, y = -5(-6), or y = 30, when x = -6.

The solution is (-6, 30)

How much more of his allowance did Nathan spend on the
SVETLANKA909090 [29]

Answer:

x(x+ 1 + 2) + y   x= 7 y=4   the actual difference is £56 = 26/28= 13/14. Reasons, He was under 15 but over 13 = 13/14 to be far too busy spending a set amount that cost multiples of the ticket. He spent so much and realized within his allowance he only managed to justify the amounts on snacks - this proportion and perhaps, spending inside the cinema as he was already there.  

Step-by-step explanation:

Expand the brackets

7 x 7 + 1 + 4 = 56 spent on snacks.

The following section is a statement from the rental agreement Tim signed when he rented his car this past weekend. “Upon checko
Gnom [1K]

Answer:

C. The representative failed to have Tim initial by the fuel level on the Check-Out sheet.

Step-by-step explanation:

After reading the paragraph, we can eliminate B, by seeing that the representative did give him a copy of the Check-Out sheet, as quoted. "Since Tim didn’t have any questions, the clerk handed him the keys and a copy of the Check-Out sheet and wished him well.".

We can also eliminate A and D, as the contract stated nothing about dents or the oil level in the car.

The answer is C, as the representative failed to have Tim initial on the Check-Out sheet. That is a requirement for the contract to be valid, as stated. "The approximate fuel level will be recorded on the Check-Out sheet and verified with initials by the vehicle Renter.". However, Tim never initialed by the fuel level, as stated here. "...the agency representative turned on the car, took note of the fuel level, and indicated it on the Check-Out sheet. Since Tim didn’t have any questions, the clerk handed him the keys and a copy of the Check-Out sheet and wished him well.". No where here does it state that Tim initialed on the Check-Out sheet, meaning that he didn't. Him not doing so invalidates the contract.

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 367
Tresset [83]

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes

The side lengths in yards of a triangle and a square are shown in the diagram. The perimeter of the triangle is equal to the per
Tatiana [17]

The value of x given the perimeter of the square is 6.

<h3>What is the value of x?</h3>

The first step is to determine the perimeter of the square.

Perimeter of the square = 4 x length

4 x 2.5x = 10x yards

The perimeter of the triangle is equal to the sum of the three side lengths

2x + 4x - 2 + 2x + 14 = 10x

Combine similar terms

14 - 2 = 10x - 2x - 4x - 2x

Add similar terms

12 = 2x

Divide both sies by 2

x = 6

Yesterday, Tammy went on a bike ride. Her average speed was 8 miles per hour. Today, she went on another ride, this time averagi
Stels [109]

Answer:

y=120-4x

Step-by-step explanation:

Here we are given the average speed for Day 1 and Day 2 and the time of ride . We asked to Find an expression to determine the total distance travelled in two days.

Day 1 :

Avg Speed = 8 mph

Let the time for travelling = x hrs

Hence Distace Travelled D1= Speed x Time

D1=8x

Day 2 :

Avg Speed = 12 mph

Total time of travelling for two days is given as 10 hours . Hence the time of travelling for day 2 is

= (10-x) hrs

Hence Distance travelled in Day 2 D2 = speed x time

D2 = 12(10-x)

D2=120-12x

Total Distance travelled = D1 + D2

= 8x+120-12x

=120-4x

If the total distance travelled is denoted by y

The expression will be

y=120-4x
