Answers is C
Step by step solution is attached
C. y - 3 = 2/3(x-3)
Nothing much to do here except examine each equation and plug in the numbers to see if it's true.
a. y + 3 = 3/2(x+3)
Try 3,3
3 + 3 = 3/2(3+3)
6 = 3/2(6). And no need to go further, it's obviously not equal.
b. y - 3 = 3/2(x-3)
Try 3,3
3 - 3 = 3/2(3-3)
0 = 3/2(0). OK. Let's try 6,5
5 - 3 = 3/2(6-3)
2 = 3/2(3)
2 = 9/2 And it's not true, so check the next one.
c. y - 3 = 2/3(x-3)
Try 3,3
3 - 3 = 2/3(3-3)
0 = 0. Check 6,5
5 - 3 = 2/3(6-3)
2 = 2/3(3)
2 = 2. Good. Both sample points work. This is the correct answer.
Just to be sure, let's check the next option
d. y + 3 = 2/3(x+3)
Try 3,3
3 + 3 = 2/3(3+3)
6 = 2/3(6). And doesn't match.
Answer:
last one
Step-by-step explanation:
What you need to know in order to answer this:
In math, the symbol " ! " is used to indicate "factorial".
"Factorial" means the product of the integers from 1
up to the number.
Examples:
2 ! = "two factorial" = 1 * 2 = 2
4 ! = "four factorial" = 1 * 2 * 3 * 4 = 24
For this question:
10 ! = "ten factorial" = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10
= 3,628,800 .
If you look at your calculator very closely, I'll bet you
there's a key on it marked " x ! " .
Enter a whole number into the calculator, and that key
gives you the factorial of the number.
And by the way, the points aren't 'free'. I had to
give you some information in order to earn them.
