Answer:
The second graph is correct for this function.
Step-by-step explanation:
The company made combined profits of $40 million after 4 years. The profits increased $30 million per year.
Therefore the rate of change of profit function is 30 and the graph of profit function passing through the point (4,40).
Point slope of a linear function is



Add 40 both sides.

Therefore the profit function is defined as

Put x=0


Therefore y-intercept of function is -80. So, second graph is correct for this function.
Y-intercept of first graph is positive and y-intercept of third and fourth graph are more that -50, therefore option 1, 3 and 4 are incorrect.
Answer:

Step-by-step explanation:
Use the distance formula.





Ok so
x - the smallest
The other 4 are : x+1, x+2, x+3, x+4
We know that sum is 120
So
x+x+1+x+2+x+3+x+4=120
Combine like terms
5x+10=120
Subtract 10 on both sides
5x=120-10
5x=110
Divide by 5 on both sides
X=22
The third number is x+2 = 22+2=24
