Answer:
Step-by-step explanation:
Yes daddy put itbinside
15x15= 225
15x + 105= 225
15x= 225-105
15x= 120
X=8
X+ (x+1) + (x+2) + (x+3)…etc all the way up too +(x+14)=225
The first five numbers of the set: 8, 9, 10, 11, 12
Answer:
Analyzed and Sketched.
Step-by-step explanation:
We are given 
To sketch the graph we need to find 2 components.
1) First derivative of y with respect to x to determine the interval where function increases and decreases.
2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

is absolute maximum

is the point concavity changes from down to up.
Here, x = 0 is vertical asymptote and y = 0 is horizontal asymptote.
The graph is given in the attachment.
So we start with the $60 untouched.
Then we add the tax which is $60•0.07= 4.20 that is the tax
Then add the tax to the total $60 + $4.20= $64.20
Next we must add the tip so $60•0.15= 9.
Then $64.20 + $9.00 = $73.20
Total cost of meal $73.20
Any questions? :)
