Answer:

g(x)=x+8

Step-by-step explanation:

Translating a function up is very simple, all you need to do here is add 8.

If you want to think of it logically,

f(x)=x

the whole right side of the function here can be our output. If x is 8, then the output, or height, is also 8. if you wanted to translate that up to 10, you'd simply need to add 2 to it, meaning x+2. Then, at any given point on the function, it'd be 2 higher than it would be otherwise.

A number is 2/3 if another number. the sum of the numbers is 50. find the numbers
slava [35]

A number is 2/3 of another number.  Both added together equals 50.

One of these numbers consists of three parts, and the other consists of two of those three parts.  So, there are 5 equal parts in total.

Thus we need to divide 50 by 5.  50 divided by 5 equals <u>10</u>.

The first number, which has three parts, is 30.  The second number, which as two parts, is 20.

I hope this makes sense to you.  :D  Good luck in all your studies!
