<span>-6y + 14 + 4y = 32
Combine like terms:
-2y + 14 = 32
Take away 14 from both sides:
-2y = 18
Divide by -2 on both sides:
y = -9
Answer: y = -9 (Answer A)</span>
Answer:
Step-by-step explanation:
Two equations of planes are given.
We have to find the equation of the line which is formed by intersection of these two planes in parametric form

Let us eliminate one variable
Multiply I equation by 5 and subtract II from 5 * I



Or 
Consider II equation
5x+y-z=4

Let z=z
x = \frac{3z-16}{16} and y = \frac{31z}{16}-1
Answer:
4 M + 2 N = 120
Step-by-step explanation:
If we name "M" the number of tables for four people, and "N" the number of tables for two people, then the total number of people to be seated using M tables (of four people) would be the product "4 * M".
Similarly, the total number of people to be seated if the owner has N number of two person tables, would be: "2 * N".
Therefore, if the owner has M four people tables and N two person tables, the total number of people seated at the restaurant would be the addition:
4 * M + 2 * N. Since he wants this number to be 120, we complete the equation making this expression equal to 120:
4 * M + 2 * N = 120
Circumference = 2 pi r
Circumference = 2 x 3.15 x 8.5 m
Circumference = 53.4 metres
