Answer:
They will need 11 tables
Step-by-step explanation:
The first 10 will seat 5, the 11th will seat the final 3.
I think the answer is D
Explanation:
Linear functions are those whose graph is a straight line.
You set up a proportion so: 12/x and 40/100
Cross multiply so 12 times 100 = 1200
and 40 times x = 40x
1200 divided by 40 = 30 minutes total
You know that he already know he spent 12 minutes doing it so
30 - 12 = 18 more minutes
The slope is (3, 2) when you go up on the graph you count spaces, the first number is your y axis, when you go right on the graph it is the same thing except for the fact that it is the x axis, if you were going down or left the answer would be negative, but in the same order,
6.5*6.5=42.25
1.5*1.5=2.25
(6.5)^2-(1.5)^2=42.25-2.25=40
