Answer:
x and y = 0
the question looks weird and almost wrong because when you subtract the equations, you are left with nothing
Step-by-step explanation:
Multiply the top equation by 3 to make the -x a -3x instead.
Then do the top equation - the bottom equation
At this point you should be left with x
Answer:
1. 4 categories are shown in the rows.
2. 2 categories are shown in the columns.
3. The number of 14 year olds that consider winter their favorite season is 12.
4. Total number of people polled is 82.
Step-by-step explanation:
The question is to test the ability of a student to group data using a frequency table accurately, and make appropriate deductions from it. Consider the attachment for the accurate table required to answer the given questions.
If the given information is grouped as required, thus the answers to the questions are:
i. 4 categories are shown in the rows.
ii. 2 categories are shown in the columns.
iii. The number of 14 year olds that considers winter their favorite season is 12.
iv. Total number of people polled is 82.
Answer:m=the slope of the line
(x1, y1)= a given point on the line (x,y)=any point on the line
Step-by-step explanation:
The general equation of the line is 3x−2y−4
Answer: she printed 200 programs
Step-by-step explanation:
Let x represent the number of programs that were printed.
The printing cost was $0.32 per program. This means that the total cost of printing x programs would be 0.32 × x = $0.32x
They were priced at $0.50 each. This means that the total revenue from selling x programs is 0.5 × x = $0.5x
Taylor sold all but 50 programs. It means that the number of programs sold is
x - 50 and the total revenue from the number of programs sold is 0.5(x - 50)
Revenue - cost = profit
Taylor made a small profit of $11. It means that
0.5(x - 50) - 0.32x= 11
0.5x - 25 - 0.32x = 11
0.5x - 0.32x = 11 + 25
0.18x = 36
x = 36/0.18
x = 200
