Answers

Answer:

Solve the system of equations
2y-3x=-27
5y+3x=6

Answers

Answer:

The answer to the first one is y=3/2x-27/2

The answer to the second one is y=-3/5x+6/5

Step-by-step explanation:

1. 2y-3x=-27

first, you want to add '3x' to both sides.

2y=3x-27

then you want to divide '2' from both sides. you do not want to use the 'y' because you want to keep the 'y' on its own side.

y=3/2x-27/2

2. 5y+3x=6

First, you want to subtract '3x' from both sides.

5y=-3x+6

Now, you want to divide '5' from both sides.

y=-3/5x+6/5

11 There are men and women at a meeting.

There are 28 women.

30% of the people at the meeting are men.

Work out the total number of people at the meeting.

Answers

Answer:

40 people

Step-by-step explanation:

Step one:

given data

let the total number of persons be x

There are 28 women

The number of men = 30% of x

Step two:

So the total person is given as

30/100*x+28= x

solve for x

0.3x+28= x

collect like terms

x-0.3x= 28

0.7x= 28

divide both sides by 0.7

x= 28/0.7

x= 40 people

[tex]y = 3.59 \\ x = 2 - \frac{2y}{3} \\x = 2 - \frac{2 \times 3.59}{3} \\ \\ x = - 0.39[/tex]

Answer:

y= -1/3x+2

Step-by-step explanation:

A slope intercept equation follows the format of y=mx+b. The m means slope and the b means y-intercept.

To find slope use the two points given(0,2) and (3,1). Start at the point highest on the line(0,2), and subtract the y values, for this graph 2-1. Then do the same with the x values, for this graph 3-0. Now you have your y and x values. Slope = y/x, so substitute the variables and you get 1/3. From left to right, the line is slanting downward, so it's a negative slope, which makes your slope -1/3.

To find the y-intercept, find where the line crosses the y axis and use the y value from that point. The line on this graph crosses at the point (0,2), so 2 is the y-intercept.

Lastly, put your new values into the slope intercept equation. Substitute m for your new slope and b for the y-intercept. That gives you your answer y=-1/3x+2.
