point b, o, and y are collinear on by, and bo:oy = 5/8. B is located at (4,2,) o is located at (57/8,-3) and Y is located at (x,
Lena [83]

Given: BO : OY = 5:8. Coordinate B is located at (4,2,) ; O is located at (57/8,-3) and Y is located at (x,y).

We have to determine the coordinate Y.

We will use cross section formula which states:

The coordinates (x_1,y_1) , (x_2,y_2) are divided in the ratio m_1 : m_2 by the Coordinate A. So, the coordinates of A are given by the formula:

(\frac{m_1x_2+m_2x_1}{m_1+m_2} , \frac{m_1y_2+m_2y_1}{m_1+m_2})

Here, \frac{57}{8} = \frac{5x+(8 \times 4)}{5+8}

\frac{13 \times 57}{8} = 5x+32

\frac{741}{8} = 5x+32

5x= 60.625

x = 12.125

Now, -3=\frac{5y+(8 \times 2)}{5+8}

-39 = 5y+16

-55 = 5y

y = -11

So, the coordinate is Y(12.125, -11).

Graph -3x + 9y = -27
serious [3.7K]

Answer:

So the x-intercept is (9,0) and the y-intercept is (0,-3).

So I'm going to graph both points and connect them with a straight-edge.

Step-by-step explanation:

I would graph this using it's x- and y-intercepts.

To find the x-intercept, set y=0.

-3x+9(0)=-27

-3x+0=-27

-3x=-27

Divide both sides by -3:

x=9

To find the y-intercept, set x=0:

-3(0)+9y=-27

 0  +9y=-27

       9y=-27

Divide both sides by 9:  

        y=-3

So the x-intercept is (9,0) and the y-intercept is (0,-3).

So I'm going to graph both points and connect them with a straight-edge.

Asa saves dimes and quarters so that he will have exact change for he bus. He dabs and then dumps the container that he has been
koban [17]

Asa has 15 dimes and 32 quarters.

Step-by-step explanation:

Given,

Total coins = 47

Worth of coins = $9.50 = 9.50*100 = 950 cents

1 dime = 10 cents

1 quarter = 25 cents

Let,

Number of dimes = x

Number of quarters = y

According to given statement;

x+y=47      Eqn 1

10x+25y=950   Eqn 2

Multiplying Eqn 1 by 10

10(x+y=47)\\10x+10y=470\ \ \ Eqn\ 3

Subtracting Eqn 3 from Eqn 2

(10x+25y)-(10x+10y)=950-470\\10x+25y-10x-10y=480\\15y=480

Dividing both sides by 15

\frac{15y}{15}=\frac{480}{15}\\y=32

Putting y=32 in Eqn 1

x+32=47\\x=47-32\\x=15

Asa has 15 dimes and 32 quarters.
