Answer:

y = \frac{1}{2}x - 1

Step-by-step explanation:

Do rise over run to find the slope, and this gets you 1/2

The y-intercept is at (0, -1) so put -1 in the equation

Out of 2,4,7,8,12,15,19,24,34 wich is not a multiple of 4
marissa [1.9K]

Answer:

2, 7, 15, 19, 34

Step-by-step explanation:

First, we have to know what a multiple is. A multiple is a number (n) that can be evenly divided by a certain base number (b). An evenly divided number is one that has no decimal points (ex: 1, 100, 24). For example, the multiples of 8 (b) would be 16, 24, 32, etc (n). Another example would be that 32 is a multiple of 2, 8, 16, etc. since it can be evenly divided by those numbers.

In this case, n = each of the numbers in that list, while b = 4. So now we just have to look at what numbers in our list can be evenly divided by 4.

  • 2 is not a multiple since it cannot be evenly divided by 4, since it is less than 4.
  • 4 is a multiple of 4, since 4/4 = 1, and 1 is evenly divided.
  • 7 cannot be evenly divided by 4, and thus is not a multiple of 4.
  • 8 can be evenly divided by 4, since 8/4 = 2,  and thus is a multiple of 4.
  • 12 can be evenly divided by 4, since 12/4 = 3,  and thus is a multiple of 4
  • 15 cannot be evenly divided by 4, and thus is not a multiple of 4
  • 19 cannot be evenly divided by 4, and thus is not a multiple of 4.
  • 24 can be evenly divided by 4, since 24/4 = 6, and thus is a multiple of 4.
  • 34 cannot be evenly divided by 4, and thus is not a multiple of 4

Since we're asked to find the numbers that are <em>not</em> multiples of 4, our answer to the question would be:

2, 7, 15, 19, 34

The average age of the starting lineup of an nba basketball team is 29 years. the ages of four of the five players are 25, 26, 2
Inga [223]
(25 + 26 + 29 + 32 + х) : 5 = 29
112 + х = 29 * 5
112 + х = 145
х = 145 - 112
х = 33 years - the age of the fifth player.
