18 = 2x -6 (Subtract 18 on both sides then subtract 2)
-2x = -6 -18
-6 -18 is = -24 (you add negative numbers together)
-2x = -24 (divide both numbers by -2)

X = 12

Answer:

X = ---- , y = 12

Step-by-step explanation:

Solve for x, y

X = 18

Y = 12, c ≠ 0

Consider the first equation. Subtract 2y from both sides.

cx - 2y = -6

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

cx = 18, cx - 2y = -6

Pick one of the two equations which is more simple to solve for x by isolating x on the left hand side of the equal sign.

cx = 18

Divide both sides by c.

X = __

Substitute 18/c for x in the other equation,

c x - 2y = - 6.

c x ( ---- ) - 2y = - 6

Multiply c times ----

18 - 2y = - 24

Subtract 18 from both sides of the equation.

- 2y = - 24

Divide both sides by -2.

y = 12

The system is now solved.

X = ---- , y = 12

How do I figure this out??

goldenfox [79]

The function is divided by 12, you would find it out by dividing 120 by 10 and getting 12, if you wanted to check your answer, you would do 84 divided by 7 which is 12. the answer to 12 is 1 and 24 is 2. hope this helped :))

Identify the independent and dependent variables in the following situation Julie notices that her plant grows one inch for ever

LUCKY_DIMON [66]

Answer:

Independent variable: amount of water

Dependent variable: growth of the plant

Step-by-step explanation:

In the statement "Julie notices that her plant grows one inch for every liter of water that it receives" it is implied that the growth of the plant is related proportionally to the amount of water it receives.

We know the amount of growth in function of the amount of water

The dependant variable, the result, is the growth of the plant.

Then, the independent variable is the amount of water, as it is the input to calculate the amount of growth.
