Answer:

A. x= 3, y= -2

Step-by-step explanation:

[2] 2x= 4y+14

[1] 3y+5x=9

Solve equation [2] for the variable x

[2] 2x = 4y + 14

[2] x = 2y + 7

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

[1] 5•(2y+7) + 3y = 9

[1] 13y = -26

// Solve equation [1] for the variable y

[1] 13y = - 26

[1] y = - 2

// By now we know this much :

x = 2y+7

y = -2

// Use the y value to solve for x

x = 2(-2)+7 = 3

good luck, I hope this helps!!!

What is the inverse of the function f(x) = 2x – 10?

Gala2k [10]

$\bf f(x)=\boxed{y}=2\boxed{x}-10\qquad inverse\implies =\boxed{x}=2\boxed{y}-10\impliedby f^{-1}
\\\\\\
x+10=2y\implies \cfrac{x+10}{2}=y\implies \cfrac{x}{2}+\cfrac{10}{2}=y
\\\\\\
\cfrac{x}{2}+5=y=f^{-1}(x)$

Help please! Could you explain it too?

Olegator [25]

Answer:

a. Not proportional

b. Proportional;

k = ⅞

Step-by-step explanation:

A proportional relationship is usually represented in the format, y = kx. k here represents constant of proportionality. This shows that x and y are directly proportional.

a. y = -2x + 9 is not a proportional equation.

b. y = ⅞x is a proportional equation.

Constant of proportionality: k = ⅞
