Let x = 0

Let y = 0

Look at choice A. There is a typo here. This is not an inequality. Where is choice B? No choice B given.

Let us play with choice C and D.

y - 9 > 3x - 10

0 - 9 > 3(0) - 10

-9 > 0 - 10...This is a true statement. We know that -9 is bigger than -10. Do you know why this is true?

How about D?

Again let y = 0 and x = 0.

0 + 9 > 3(0) + 10

9 > 0 + 10

9 > 10...This is untrue. We know that 9 is NOT BIGGER than 10.

Without knowing A and B, I figured out that choice C is true. We conclude that the point (0,0) AKA the origin is a solution to the inequality given by choice C.

Understand?

"help..." said the high schooler.
"No," said Life, "figure it out yourself."
Then the rejected high schooler went to watch YouTube to relieve stress, hour and hours passed by until the high schooler realized he was wasting time.
"Oh no!" He said, "I have wasted time again! How will I ever get pass high school?"
"We will help you," said the flash cards, colored pens, and highlighters "we will be your best friend."
After that day, the high schooler never had an all nighter for the rest of high school. (College is a different story)

Moral of the story: Life and cute cat videos will not help you and your homework. Paying attention in class, making flash cards, making your notes colorful with pens and highlighter are what really helps :)

Oh and asking your teacher for help is great too.

ELEN [110]

7 English and 6 Science

There are 7 * 6 ways this can be put together. Which makes 42.

Take a look at the diagram below. There are 6 possible science teachers that the student could choose after choosing E1 which is the first English teacher. Each of the remaining 6 english teachers also allow for 6 science teachers.

6*7 = 42
