Problem Set 2 A. What is the value of " for the
system below if the system has
infinitely many solutions?
2x - 5y = m
nx + 10y = -8
B. What is the solution to the
system below?
-5x = y + 2
2(2x - 1) = 3 - 3y
C.
D
How many solutions does the system
have below?
2x – 4y = 8
x + 2y = 4
Create an example of a system of
equations where substitution would be
the better method to solve it

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
