It is a function because we do not have two or more red points vertically aligned. In other words, we don't have any red points stacked. This graph passes the vertical line test.
The vertical line test is where we try to find a single vertical line passing through more than one red point. No such vertical line exists, so that's why this graph passes. Passing the vertical line test means we therefore have a function.
A function is where any input x leads to exactly one output. For instance, the input x = 9 leads to the single output y = 28. Similar situations happen with the other x values as well. If we had the two points (9,28) and (9,36), then this wouldn't be a function.
Explanation: there’s not anywhere on the graph where there’s 2 plots in the x-axis

10. The test was worth 100 points. There were 28 problems on the test. Some of the
problems were worth 3 points and others were worth 5 points. How many of each were
there?
Answers
Answer:
There are 20 3-point questions and 8 5-point questions
Step-by-step explanation:
x=3 point y=5 point
x+y=28 ----> x=28-y
3x+5y=100
3(28-y)+5y=100
84-3y+5y=100
84+2y=100
2y=16
y=8
28-8=20
Answer:
20 3-point questions and
8 5-point questions.
Step-by-step explanation:
Let there be x 3 point problems and y 5 point problems. So we have:
x + y = 28 Multiply this equation by -3:
-3x - 3y = -84
3x + 5y = 100 Adding the last 2 equations:
0 + 2y = 16
y = 8
So x = 28 - 8 = 20.

When changing something to standard form, you want all variables on one side, and the remaining numbers gone.
1) Give an example of a rational number AND an irrational number.
What is the difference between them?
2) What is the decimal equivalent of your two examples?
3) Can every repeating decimal be written as a rational number? Explain why or why
not.
Answers
Answer:
Step-by-step explanation:
A rational number is one that can be expressed as a fraction. Pi cannot be. If I tell you that the 2000th digit of pi is an 8 (which it probably isn't) and I ask you to tell me the 2001 value of pi, you have no better odds that 1/10 of getting it right.
A rational number can always be reduced to a fraction. 20 1/2 can be expressed as a fraction. It is 20.5
Pi is irrational. I don't know the value of pi beyond what a calculator can tell me. 3.14159265 The next digit is a 4. I know this only because that is what the calculator tells me.
Repeating decimals call always be represented as a fraction. For ex
x = 0.123123123123123
1000x = 123.123123123123
x = .123123123123123 Subtract
999x = 123
This comes about because in both cases what is after the decimal is the same.
x = 123/999 = 41/333

PLS HELP ME! Joye has a circular garden with a diameter of 24 feet. If she uses 2 cups of fertilizer for every 10 square feet, how much fertilizer will Joye use for her garden? Use 3.14 for pi
Answers
Answer:
90.5 cups
Step-by-step explanation:
Step one:
Given data
diameter= 24ft
radius= 12 ft
area= πr^2
Area= 3.142*12^2
Area= 3.142*144
Area= 452.448 ft^2
Hence if
2 cups of fertilizer for every 10 square feet
x cups will do for 452.448 ft^2
cross multiply we have
x= 452.448 *2/10
x=904.896/10
x=90.5 cups
