<u>Step-by-step explanation:</u>
To find the inverse, swap the x's and y's and solve for y. <em>Note: f(x) is y</em>

Answer:
No
Step-by-step explanation:
Diameter= 180cm
Circumference of each table
= πD
= 180π cm
Each table can fit
= 180π ÷70
= 8 guests (nearest whole number)
Since there are 18 tables, total number of guests
= 8(18)
= 144 guests
Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.
Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.
If that was done,
Total circumference
= 180π(18)
= 10179 cm (5 s.f.)
Total number of people
= 10179 ÷70
= 145 people (3 s.f.)
This is incorrect.
Okay, 3x just means 3•x. so 3•x-y=15. you would have to have what x and y both mean to get the correct answer. but if they just need it simplified than your answer would be 3•x-y=15
Answer:
m = -1
c = 9
Step-by-step explanation:
<em>m</em> is slope, which is the coefficient of <em>x</em>
<em>c</em> is the y-int, which is the constant
