Answer: The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.
Step-by-step explanation:
Let x= Cost of one bag of chips
y= Cost of one bag of pretzels.
As per given, we have
5x+9y=16.95 ...(i)
x+y=2.55 ...(ii)
Multiply 5 to (ii), we get
5x+5y=12.75 ...(iii)
Eliminate (iii) from (i), we get
Put value of y in (ii), we get
Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.
Answer:
m = 1; (0, 3) is the correct answer.
Step-by-step explanation:
The general equation of a line is given by:
where, m is the slope of line
c is the y-intercept and
(x,y) are the points from where the line passes.
We are given that the line passes through 2 points (-3,0) and (0,3).
Putting the values of (x,y) in the equation of line.
Putting (0,3):
So, y-intercept is (0,3).
Hence, equation of line becomes:
Putting (-3,0) in :
So, the equation of line becomes:
Please find attached graph.
m = 1; y intercept (0, 3) is the correct answer.
