Jeffrey calculated the slope between two pairs of points. He found that the slope between -5, 6 and -3, 2 is -2. He also found t

Cerrena [4.2K]

Answer:

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope between -5, 6 and -3, 2

substitute the values in the formula

$m=\frac{2-6}{-3+5}$

$m=\frac{-4}{2}=-2$

step 2

Find the slope between (-1, -2) and (0, -4)

substitute the values in the formula

$m=\frac{-4+2}{0+1}$

$m=\frac{-2}{1}=-2$

step 3

Find the slope between (-3, 2) and (0, -4)

substitute the values in the formula

$m=\frac{-4-2}{0+3}$

$m=\frac{-6}{3}=-2$

therefore

Jeffrey is correct

All of these points are on the same line because the slope between (-3,2) and( 0,-4), which are coordinates from each of the pairs above, is equal to -2

Answer:

ratios equivalent to 1/3=2/6,3/9

Step-by-step explanation:

Double number line is a diagram used when. quantities have different units.

It shows each of the quantities on its own number line with corresponding pairs of values lined up.The values of each number line are not the same unless there is a 1:1 ratio between them.

some ratios equivalent to 1:3 are;

2:6,3:9,4:12,5:15,6:18,7:21,etc

Answer:

a. k = n - 1 b. 15 c. 112

Step-by-step explanation:

I can answer a. b. and c. for you!

For a. let's say that the variable k means keys. And n means bits.

Since Millie can collect one less keys than there are bits, the equation is....

*See top*

For b. if Antonio has a 16-bit system, by looking at our equation we know that k = n - 1.

So, if n = 16, k = 15

For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.

8 x 14 = 112
