Answer:

12 years later.

Step-by-step explanation:

Let assume in X years, the table will be twice as old as the sofa.

36+X=2(12+X), X=12

Or think it the other way. The difference of ages between two things never change. So they must have a difference(of age) of 24 forever. When will this difference(24) be as same as the younger's age so that the older one is exactly twice as old as the younger? 12 years later when the sofa is 24.

What is the solution to a system whose equations are parallel?
Rina8888 [55]
One solution- if the graphs of the equations intersect, then there is one solution that is true for both solutions.

No solutions- If the graphs of the equation do not intersect (example-if they are parallel) there are no solutions that there are true for both equations.

Function g can be thought of as a scaled version of f(x)=x^2<br><br><br> Write the equation for g(x)
tangare [24]

A scaled version means that our leading coefficient will change. Let's set up an equation to find our leading coefficient, a.

g(x) = a * x^2

Now that we have our equation, we need a point that is on g(x). The point given is (4,8). Let's use that point and plug x and y into our equation so that we can solve for a.

8 = a * (4)^2

8 = a * 16

a = 1/2

All that's left to do is plug in our a value into g(x).

g(x) = 1/2 x^2

Hope this helps!! :)
