5. Suppose y varies directly with x, and y= 14<br> when x= 2. What is y when x = 6?

Oduvanchick [21]

Answer:

$\boxed{42}$

Step-by-step explanation:

The formula for direct variation is

y = kx

1. Calculate the value of k

y = 14 when x = 2

$\begin{array}{rcl}14& = & k \times 2\\k & = & \dfrac{14}{2}\\& = & 7\\\end{array}$

2. Value of y

k =7; x = 6

$\begin{array}{rcl}y & = & 7 \times 6\\ & = & \mathbf{42}\\\end{array}\\y = \boxed{\mathbf{42}} \text{ when x = 6}$

6x-2=7x+9 find x plz help

steposvetlana [31]

Answer:

$x=-11$

Step-by-step explanation:

$6x-2=7x+9$

Add 2 to both sides:

$6x-2+2=7x+9+2$

$6x=7x+11$

Subtract 7x from both sides:

$6x-7x=7x+11-7x$

$-x=11$

Divide both sides by -1:

$\frac{-x}{-1}=\frac{11}{-1}$

$x=-11$
