Tim wrote a statistical question because he is trying to figure out how many books were read in total. Jenna just wanted to know what the first book on the list was.
Answer:
Each pencil costs $0.07 and each eraser costs $0.03
Step-by-step explanation:
System of linear equations
It refers to the study of systems when n variables are related in m linear equations, each one is not independent from the others. Solving such systems can be done following very diverse approaches.
Let p=the price of each pencil while e is the price each eraser
Julio bought 4 pencils and 3 erasers, spending

David bought 3 pencils and 4 erasers, spending

The system of equations is written in the form

We'll solve it by reduction. Multiplying the first equation by -3 and the second by 4:

Adding both equations:
7e=0.21
e=0.03
Multiplying the first one by -4 and the second by 3

Adding both equations:
-7p=-0.49
p=0.07
Solution: Each pencil costs $0.07 and each eraser costs $0.03
Whats the question. I need the question to answer.
Answer:
-3/4
Step-by-step explanation:
2 is an integer
-8/2 can be simplified to -4 which is an integer
-3/4 is a fraction that when divided produces a decimal. It is not an integer.
-5 is an integer
Answer:
f(1) = - 2
Step-by-step explanation:
f(1)
Means find the value of y when x = 1
From the graph the point (1, - 2)
is the point where y is - 2 and x is 1
Thus
f(1) = - 2
