Answer:

Answer is <u>-3</u> x + <u>2</u> y = <u>-22</u>

<u />

Step-by-step explanation:

Given System of equations,

3x + 6y = -8 ............(1)

2y = 3x - 22 ..........(2)

We have to re write second equation so that terms in the system align.

In equation (1),

term with x variable and y variable are on LHS while constant term is in RHS.

In equation (2)

term with y variable is in LHS and term with x variable & constant term in RHS.

So, we bring term with x variable form RHS to LHS in equation (2).

we get

2y - 3x  = -22

Now rearranging,

-3x + 2y = -22

Therefore, Answer is <u>-3</u> x + <u>2</u> y = <u>-22</u>

2y = 3x - 22      subtract 3x from both sides

-3x + 2y = -22

Answer:

\left\{\begin{array}{ccc}3x+6y=-18\\-3x+2y=-22\end{array}\right

Analyze is the product of 0.4×1.8 greater than or less than 0.4?please explain to me
AnnZ [28]
Remember that multiplying is how many times you add a number to itself. If you multiply by 3, you add the first number to itself 3 times.

When you multiply a given number by 1, you get the first number (it doesn't change).

When you multiply by a number less than one, say, one half, you'll end up with half of the original number --> a smaller number.

When you multiply a number by more than one, you will get a number bigger than the original because you are adding it to itself more than once. Even if it is a fraction or decimal, if it is greater than 1, then the new product will be larger than the original number.

Hope this helps! :)

Pada hari kantin sebanyak 800 naskah kupon telah dijual,harga senaskah kupon masing masing rm 30 dan rm 50 .jumlah wang diperole
solniwko [45]

Answer:

Step-by-step explanation:

On the day of the canteen, 800 coupons were sold, the price of each coupon was RM 30 and RM 50 respectively. The amount of money earned from the sale of coupons was RM30000. How many copies of RM30 and RM50 coupons were sold?

Let:

RM 30 = x

RM 50 = y

x + y = 800 - - - (1)

30x + 50y = 30000 - - - (2)

From (1)

x = 800 - y

Put x = 800 - y in (2)

30(800 - y) + 50y = 30000

24000 - 30y + 50y = 30000

24000 + 20y = 30000

20y = 30000 - 24000

20y = 6000

y =

Consider the scatter plot.
Leno4ka [110]

<u>Answer:</u>

The correct answer option is: The y-intercept of the line of best fit shows that when time started, the distance was 5 feet.

<u>Step-by-step explanation:</u>

We are given a scatter plot with a best fit line as shown on the given graph.

The equation of the best fit line is given by:

y = 0.75x + 5

So with the help of the equation and by looking at the given graph, we can conclude about the representation of the y intercept that the the y-intercept of the line of best fit shows that when time started, the distance was 5 feet.

Since the distance shown on the y axis is already 5 when the time started at 0 minutes.
