If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when c is 2?

1 answer:

7 0

Direct variation has the for y=kx (inverse variation has the form y=k/x)

Since we are given a point we can solve for the constant of variation, k

48=6k so

k=8 so our equation is:

y=8x so

y(2)=8(2)

y(2)=16

So y=16 when x=2

Solve the equation for x −6x+2=8

Vikentia [17]

Answer:

x = -1

Step-by-step explanation:

−6x+2=8

Subtract 2 from each side

−6x+2-2=8-2

-6x = 6

Divide by -6

-6x/-6 = 6/-6

x = -1

Vanyuwa [196]

Answer:

12a + 24 = 6(2a + 4)

Step-by-step explanation:

Given the numbers :

4, 12a 6 2a and 24 ; create an equivalent expression :

12a, 2a, 4, 6, 24

We could separate tbe constant terms and those with variables :

12a, 2a ; 6, 4, 24

We could put the larger digit to one side

12a + 24 = 6(2a + 4)

This way the Right hand side is equal to the left hand side.

Check:

12a + 24 = 6(2a + 4)

12a + 24 = 12a + 24

Hence, the proof
