The sum of two numbers, x and y, is more than 8. When you double x and add it to

see below

Step-by-step explanation:

so your two inequalities would be

x+y>8

and

2x+y<14

we can put both of these into slope intercept form

y>-x+8

y<-2x+14

and now we can graph!

see image attached:

both lines are dotted because it is greater than and less than, not equal to.

slope intercept form is y=mx+b which is y=slopex+y intercept

we can first plot the y intercept and use the slope to find the other points

slope is rise/run

The correct options are : The range stays same and The domain stays same.

Explanation:

Since, given function, , where x belongs to the domain of the function and f(x) makes the range of the function.

Here, Both domain and range are the set of real number.

According to the question, when we increase a by 2 but the value of b remains same.

Then, the new function is ,

But,  the range and domain of this function is also the set of real number.

So, there is not any change in range and domain of the function.

Thus, Options first and third are correct.
