Answer:

$92=B\\A=106$

Step-by-step explanation:

So i did it like this

A= Train A B= Train B

$A+B=198\\A-B=14\\A=198-B\\A=14+B\\(14+B)+B=198$

$14+2B=198$

$184=2B\\92=B\\A=106$

CHECK:

$106+92=198\\198=198$

$106-92=14\\14=14$

The equation of a line is 5x − 3y = 6. Which is the y-intercept of the line?

oksian1 [2.3K]

Answer:

y - intercept. = 2.

Step-by-step explanation:

Given : The equation of a line is 5x − 3y = 6.

To find : Which is the y-intercept of the line.

Solution : We have given 5x − 3y = 6.

Equation of line y = mx +b

Where , m = slope , y intercept = b

Now we convert the 5x − 3y = 6 in line form y = mx +b

5x − 3y = 6

On subtracting both sides by 5x

-3x = - 5x + 6

On dividing both sides by - 3.

x = $\frac{5x}{3}+2$ .

We cans see m = $\frac{5}{3}$ , y - intercept. = 2.

Therefore, y - intercept. = 2.

Answer:

The answer to your question is 11.4 units

Step-by-step explanation:

Data

A (-3, -1)

B ( 0, 3)

C ( 1, 2)

Perimeter = ?

Formula

d = $\sqrt{(x2 - x1)^{2} + (y2 - y1)^{2}}$

Process

1.- Find the length between the points

dAB = $\sqrt{0 + 3)^{2} + (3 + 1)^{2}}$

dAB = $\sqrt{3^{2}+ 4^{2}}$

dAB = $\sqrt{9 + 16}$

dAB = $\sqrt{25}$

dAB = 5

dBC= $\sqrt{(1 - 0)^{2} + (2 - 3)^{2}}$

dBC = $\sqrt{1^{2} + (-1)^{2}}$

dBC = $\sqrt{1 + 1}$

dBC = $\sqrt{2}$

dAC = $\sqrt{(1 + 3)^{2} + (2 + 1)^{2}}$

dAC = $\sqrt{4^{2} + 3^{2}}$

dAC = $\sqrt{16 + 9}$

dAC = $\sqrt{25}$

dAC = 5

2.- Perimeter

P = AB + BC + AC

P = 5 + $\sqrt{2}$ + 5

P = 10 + $\sqrt{2}$

P = 10 + 1.42

P = 11.4
