A system of equations has an infinite number of solutions when after solving the system, you end up with a true statement.
For example, let’s say you solve a system of equations and your result is 5=5. 5=5 is a true statement, but it doesn’t tell us anything about the x or y value solutions to the system. So because we’re only left with 5=5, there are infinite solutions to the system.
Answer: 55
Step-by-step explanation:
Let the number of cars washed last year be denoted as x.
This year, he washed 14 fewer cars than during last year's car wash. This will be denoted as x-14.
We can then represent them in an equation as:
x + (x - 14) = 96
2x - 14 = 96
2x = 96 + 14
2x = 110
x = 110/2
x = 55
Therefore, he washed 55 cars this year
Answer:
b. the function is always positive
You have the answer right there near the end.
2-1/2 x 10 = 25 miles.
For A for the mean just add them all up which would be which is 430 and divide by the number of numbers there is so 430 divided by 8 = 53.75 and the median order them from least to greatest and find the one in the middle which is 52 and 56 when there's two just add them and then divide it by 2 which is 54
Hope this helped :)
