When
y = x \\ y = 16 \\ x = 8
you would have to use comon multiples to find what both numbers have in common, a short way of finding this would be
16 \div 8 = a
where (a) is the answer of the equation, (a) would be 2 because 8*2=16 meaning
y = 2x

y = 16 \\ x = 8 \\ x = 8 \times 2 = 16 \\ y = 16 \times 2 = 32
so when x(8) equals 16 it would mean 8 is multiplied by 2 and so once x(8) is multiplied by 2 y(16) would also have to be multiplied by 2 which is 32
so y =32 I'm sorry if I'm wrong

The equation that represents the canned goods order is 24x+64y=384
Lubov Fominskaja [6]

The x-intercept is (16, 0) and y- intercept is (0, 6).

<h3>What is intercept?</h3>

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Given: 24x+64y=384

For y- intercept, put x=0

Then,

24*0+64y=384

64y= 384

y= 6

Now, for x- intercept put y=0

Then,

24x+64*0=384

24x= 384

x= 15

Hence, the x-intercept is (16, 0) and y- intercept is (0, 6).

Help please ..........​
olganol [36]

Answer:

7.  combination; 25C6 = 177100

8.  combination; 15C5 = 3003

Step-by-step explanation:

7. The order of the committee member selections is not important. (It would be if specific people filled specific positions on the committee.) Hence, the number is a number of combinations of 25 people taken 6 at a time.

__

8. The order of players is not important, as it might be if specific choices filled specific positions on the team. (The problem statement gives no indication that is the case. It is only by our knowledge of basketball teams that we entertain the possibility that order might be important.) Hence, the number is a number of combinations of 15 people taken 5 at a time.

_____

Of course, nCk = n!/(k!(n-k)!)
