<h3>What is an equation?</h3>

In its simplest form in algebra, the definition of an equation may be a mathematical statement that shows that two mathematical expressions are equal. It consists of variables dependent and independent variables. They can be linear or non-linear in nature.

Let the number Max is thinking be 'x'

He adds 8 to the number and then he doubles the sum.

Sum means we are adding a number to x, in this case it is 8.

50 POINTS!!! <br> Which function is shown on the graph below?<br> See photo
Volgvan

Answer:

C. y=\sqrt{2x-6}+1

Step-by-step explanation:

From the graph of the function, we can see that the domain of the function is x\ge 3, the range of the function is y\ge 1.

Consider the parent function y=\sqrt{x}.

The domain of this function is x\ge 0, the range of this function is y\ge 0.

The function y=\sqrt{2x-6}+1 has

the domain

2x-6\ge 0\\ \\2x\ge 6\\ \\x\ge 3

and the range

y\ge 0+1\\ \\y\ge 1

All other options have different domain, or the range, or both the domain and the range.

ArbitrLikvidat [17]

Answer:

x=67.4

Step-by-step explanation:

well sin30:1/2

So y is not 30 since 5/13 doesn’t equal 1/2

So it’s either the the third or fourth option

And x>y

So option 4 is correct
