Answer:
9. y=-2x+3
10. y=-1x+7
Answer:
1/4
Step-by-step explanation:
Probability is essentially (# times a specific event occurs) / (# times any general event occurs).
Here, the "specific event" is selecting a multiple of four. The multiples of 4 from 1 to 20 are: 4, 8, 12, 16, and 20 - there are 5 of these. So, the number of times the specific event can occur is 5.
The "general event" is selecting any number out of the 20. Since there are 20 numbers, then there are 20 ways that a general event occurs.
So, the probability is 5/20 = 1/4.
Answer:
A. 5
Step-by-step explanation:
5 ÷ 1 = 5
10 ÷ 2 = 5
15 ÷ 3 = 5
Your coefficient is the number and your variable is the letter. So in this case your coefficients are 9 and 20 and your variables are x and y!
Answer:
20
Step-by-step explanation:
-3x+20=-5x+20+2x
reduced:
-3x+20=-3x+20
subtract 20 from each side
Then
-3x=-3x
