-5x +13y =-7 5x +4y=24 x= y=

1 answer:

3 0

X=4
Y=1
You already have the equation done from that equation you cross out the -5x and 5x then add 13+4 it gives you 17 the add -7+34 it gives you 17 that’s when you get x. Now ones you have x plug in the 1 into any equation I prefer the ones that don’t have negative numbers, ok so the plug in 1 into the Y and then it would be 5x+4(1)=24, so you know 4(1) is 4 so then subtract 24-4 which gives you 20 and then bring down 5x and then divide 24/5 and then you get what X is and it is 5.

Y = 2/3 x -3 y = -3/2 x +2 what statement about the lines are true

Hoochie [10]

Answer:

The product of the slopes of lines is -1.

i.e. m₁ × m₂ = -1

Thus, the lines are perpendicular.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

m is the slope

b is the y-intercept

Given the lines

y = 2/3 x -3 --- Line 1

y = -3/2x +2 --- Line 2

The slope of line 1

y = 2/3 x -3 --- Line 1

By comparing with the slope-intercept form of the line equation

The slope of line 1 is: m₁ = 2/3

The slope of line 2

y = -3/2x +2 --- Line 2

By comparing with the slope-intercept y = mx+b form of the line equation

The slope of line 2 is: m₂ = -3/2

We know that when two lines are perpendicular, the product of their slopes is -1.

Let us check the product of two slopes m₁ and m₂

m₁ × m₂ = (2/3)(-3/2 )

m₁ × m₂ = -1

Thus, the product of the slopes of lines is -1.

i.e. m₁ × m₂ = -1

Thus, the lines are perpendicular.

what is the value of the x variable in the solution to the following system of equations? 2x 2y = 6 x 3y = −1 a. −2 b. 2 c. 5 d.

tatuchka [14]

2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)

(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)

(3) - (4) => 4x = 20
x = 20/4 = 5

What is the third quartile of the following data set 24,20,35,39,28,42,25,29,44,21,37

strojnjashka [21]

First, arrange the data:

20, 21, 24, 25, 28, 29, 35, 37, 39, 42, 44

You can use the formula 3/4 multiplied by the number of data + 1 to find the position of the 3rd quartile.

so it's going to be 3/4 x (11+1) = 9th position

the number in 9th position is 39 so that's the 3rd quartile
