Answer:

Step-by-step explanation:

In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4. This means it is not a function, but it is paired with two different values.

Find the value of x if mPYA 12x 20 and m LPLA 110O 220O 240O 20O 40

romanna [79]

M<PLA = 1/2 m PYA
110 = 1/2 (12x - 20)
12x - 20 = 220
12x = 220 + 20 = 240
x = 240 / 12 = 20

Answer:

[2] x = -5y - 4

// Plug this in for variable x in equation [1]

[1] 2•(-5y-4) - 5y = 22

[1] - 15y = 30

// Solve equation [1] for the variable y

[1] 15y = - 30

[1] y = - 2

// By now we know this much :

x = -5y-4

y = -2

// Use the y value to solve for x

x = -5(-2)-4 = 6

Solution :

{x,y} = {6,-2}
