Answer:
11.0905365064
11.1 (rounded)
Step-by-step explanation:
To find (f+g)(x), add the equations and simplify by combining like terms.
(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5
Final answer: C
Remember that (x/2) is the same as (1/2)x. They both represent half of x.
Hello!
To calculate the slope given two points, we use the formula y2-y1/x2-x1. You can switch the ones and twos and the slope will be the same. We will have (-1,3) represent (x1,y1) and (5,3) represent (x2,y2).
Now we plug these numbers into the equation.
3-3/5+1
0/6
Undefined
Since the number is divided by zero, the slope is undefined, or the line is vertical. Just to check, we will switch the ones and twos.
3-3/-6
0/-6
Undefined
Our line is vertical, therefore our slope is undefined.
I hope this helps!
