Answer:

-2/3

Step-by-step explanation:

the triangle on the line is 2 by 3 and the slope formula is:

rise over run aka length over height!

Since the line is going downhill it would be negative!

Hope this helped!

Answer:

-2/3

Step-by-step explanation:

Start with looking at the y-axis, and count down the line until you get to a definite point. So we can see there is a definite point at (0,4) and (3,2). To get from (0,4) to (3,2), we have to go down 2 (-y) and to the right by 3 (positive x).

Slope formula is y/x, so our slope would be -2/3!

Find two numbers such that the sum of the first and three times the second is 5 and the sum of the second and two times the firs
Sav [38]

Answer:

first number= 19/5

second number= 2/5

Step-by-step explanation:

first number= a

second number= b

a+3b=5   equation 1

b+2a=8  equation 2

using equation 2 we have

b=8-2a

using equation 1 we have

a+3(8-2a)=5  

a+24-6a=5

24-5=6a-a

19=5a

a=19/5 = first number

so using b=8-2a

we have

b=8-2(19/5)

b=8-(38/5)

b=2/5 = second number

Solve the system of equations - 6x + 5y = 0 and -5x + 5y = -5 by combining
Anna [14]

9514 1404 393

Answer:

  (x, y) = (-5, -6)

Step-by-step explanation:

The coefficients of y are the same, so we can eliminate y by subtracting one equation from the other. Here, we choose to subtract the first from the second, so that the coefficient of x ends up positive.

  (-5x +5y) -(-6x +5y) = (-5) -(0)

  x = -5 . . . . . . simplify

  -6(-5) +5y = 0 . . . . . . substitute x into the first equation

  6 +y = 0 . . . . . . . . . .  divide by 5

  y = -6 . . . . . . subtract 6

The solution to the system of equations is (x, y) = (-5, -6).

Find the x- and y-intercepts for the linear equation –3x + 4y = 24.
Sav [38]

Answer:

x- intercept = - 8, y- intercept = 6

Step-by-step explanation:

To find the x- intercept let y = 0 and solve for x

- 3x + 4(0) = 24

- 3x = 24 ( divide both sides by - 3 )

x = - 8 ← x- intercept

To find the y- intercept let x = 0 and solve for y

- 3(0) + 4y = 24

4y = 24 ( divide both sides by 4 )

y = 6 ← y- intercept

What is the alternating sum of digits
Morgarella [4.7K]

Answer:Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Hope this helped
