Twenty five more than twice a number is fifty five. What is the number?

Step-by-step explanation:

Note all operations:

Create an equation, and make the unknown number be x. 25 is added to x multiplied by 2, which, in all, equals 55:

Now solve for x. Subtract 25 from both sides:

Divide both sides by 2:

The number is equal to 15.

:Done

CHECK:

Insert the value of x to see if it is true:

This is true, so the value of x is also true.

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
