The slope of y = 3x is 3, and the slope of y = -3x is well, yes, you guessed it, is -3, same value, just different sign, and when that happens the slopes are just mirroring each other, in this case, the mirror line, line of symmetry, is the y-axis, notice in the picture below.
Answer:
Step-by-step explanation:
<u>We know that </u>
<u>We also know that </u>
<u>Since 5! = 1*2*3*4*5 is divisible by 15:</u>
- any n! with n ≥ 5 is divisible by 15.
We need to find the remainder when 1! + 2! + 3! + 4! is divided by 15 as all the rest are divisible by 15.
<u>The sum is:</u>
- 1! + 2! + 3! + 4! = 1 + 2 + 6 + 24 = 33
<u>The remainder is:</u>
As we see the remainder is 3
Answer:
50
Step-by-step explanation:
(-5)* (-5) = 25; as the negatives cancel out
