Answer:
whats a slope?
Step-by-step explanation:
Hello there!
I'm assuming since there is no question, that you want an explanation for composite functions.
Today, I want to introduce you to a very new way of looking at functions. Think of a function as a machine. I'll call this machine f. When you plug something into this machine, it is an x-value. The machine changes the x-value into a new value which is called a y-value. This is how a function works.
With composite functions though, things get a little bit tricky. To make f(g(x)), you need to plug in x into the g machine, and it will give you an output. (y-value) The next thing you do is take that y-value and plug it into the g machine. The g machine then gives you a new value. This value is f(g(x)).
Let's do an example together...
f(x)=3x and g(x)=x²+4
if we want f(g(x)), first plug in x to the g machine. when plugging in x to the g machine, we get x²+4 as given in the question.
Now we must plug in g(x) into the f machine. Since g(x) is x²+4, we just replace x with x²+4.
We get 3(x²+4)
This means that f(g(x))=3(x²+4)

Answer:
y = 40 is the answer
Step-by-step explanation:
Let the number be y
10 more than 2 times a number = 10 + 2×y
equal to 2 times the number plus 50. = 2 × y + 50
10 + 2y = 2y + 50
combine the like terms
2y - 2y =50 - 10
0 = 40
the number supposes be 40 but the number is represented by 0
i think some thing is missing in your question
y supposes be 40 not 0 = 40
Hope this helps!
