What is the equation of the horizontal line passing through (3, 8)?

Answers

Answer 1

Answer:

Y= -5

Step-by-step explanation:

If y always equals -5 then the x value will change but the y value will not. This means that the slope of the line is zero and will be parallel to the x axis, which is the horizontal line.

what is 8.154 to 1 decimal place?
​

Answers

What is 8.154 rounded to 2 decimal places?" is the same as asking, "What is 8.154 rounded to two decimal points?" or "How to round 8.154 to two decimal places."

The main point is that you want to round 8.154 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 8.154. To eliminate the last digit in 8.154, we use the following Two Decimal Places Rules to get the answer:

Two Decimal Places Rule #1: If the last digit in 8.154 is less than 5, then remove the last digit.

Two Decimal Places Rule #2: If the last digit in 8.154 is 5 or more and the second to the last digit in 8.154 is less than 9, then remove the last digit and add 1 to the second to the last digit.

Find the solution of the system of equations -7x-3y=-20 3x+6y=-15

Answers

9514 1404 393

Answer:

  (5, -5)

Step-by-step explanation:

I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).

__

We can add the second equation to 2 times the first to eliminate the y-variable.

  2(-7x -3y) +(3x +6y) = 2(-20) +(-15)

  -11x = -55 . . . . . collect terms

  x = 5 . . . . . . . . . divide by -11

Substituting this value into the second equation, we have ...

  3(5) +6y = -15

  6y = -30 . . . . . . . . subtract 15

  y = -5 . . . . . . . . . . divide by 6

The solution is (x, y) = (5, -5).

A ticket for a seat at a school play costs £2.95
There are 21 rows of seats.
There are 39 seats in each row.
The school will sell all the tickets.
Work out an estimate for the total money the school will get.

Answers

Answer:

Answer vary :

2.95(21 times 39) = $2,416.05

Step-by-step explanation:

honestly in my opinion that the answer. so we’re trying to find out how much money the school will earn.

if each seat cost 2.95 we need to find out how many seats are their?

-21 times 39 = 819

we multiplied the rows and seats find out how many seats their are and the answer is 819.

after you do that now we have to find out how much money they will earn from selling all 819 seats.

-819 times 2.95 = 2,416.05

we then multiplie all of the seats wich is 819 seats by 2.95 wich is the cost of one seat and got 2,416.05, and that’s the answer we’ve been looking for.

and that’s how I got my answer.

The total money school will get is £2416.05 on a play.

What is multiplication?

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

A ticket for a seat at a school play costs £2.95

There are 21 rows of seats.

There are 39 seats in each row.

That means,

there are total 21 x 39 =  819 seats.

So, the total money the school will get,

= 819 x £2.95

= £2416.05

Therefore, school makes £2416.05 on a play.
