Slope is m= y2- y1 / x2- x1.

Billy flipped both where the numbers go, and in which order they should be in.

It should be -5-5 / -2-2 giving you zero (0).

Explain the distance formula. Then use it to calculate the distance between A(1,1) and B (7,-7)
crimeas [40]

The distance formula is given by:

d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }

We are given two points A and B as

A(1,1) and

B(7,-7)

so we have ,

x1 = 1 , y1=1

x2= 7 and y2=-7

Plugging these in the formula we have:

d=\sqrt{(7-1)^{2}+(-7-1)^{2} }

d=√(36+64)

d=√100

d=10

Answer: The distance between A(1,1) and B(7,-7) is 10

Use the permutation formula to solve a problem when n = 15 and r = 4.
barxatty [35]

nPr =  \frac{n!}{(n - r)!}

15P4 =  \frac{15!}{(15 - 4)!} = \frac{15!}{11!} \\  = \frac{15 \times 14 \times 13 \times 12 \times 11!}{11!} \\ 15 \times 14 \times 13 \times 12 = 32760

Algebra Test pls help

Answer:

Option 3

y + 16 = 8(x + 2)

Step-by-step explanation:

<h3><u>Given</u>;</h3>
  • x = 2, 4, 6, 8
  • y = 16, 32, 48, 64

Now, Put the values in equation 1

y – 16 = 8(x – 2)

  • For x = 2 and y = 16

y – 16 = 8(x – 2)

16 – 16 = 8(2 – 2)

0 = 8

Here, L.H.S ≠ R.H.S

So, Option 1 is incorrect

Now, Put the values in equation 2

y – 16 = 8x – 2

  • For x = 2 and y = 16

y – 16 = 8x – 2

16 – 16 = 8(2) – 2

0 = 14

Here, L.H.S ≠ R.H.S

So, Option 1 is incorrect

Now, Put the values in equation 3

y + 16 = 8(x + 2)

  • For x = 2 and y = 16

y + 16 = 8(x + 2)

16 + 16 = 8(2 + 2)

32 = 8(4)

32 = 32

Here, L.H.S = R.H.S

Check other values of x and y

  • For x = 4 and y = 32

y + 16 = 8(x + 2)

32 + 16 = 8(4 + 2)

48 = 8(6)

48 = 48

Here, L.H.S = R.H.S

  • For x = 6 and y = 48

y + 16 = 8(x + 2)

48 + 16 = 8(6 + 2)

64 = 8(8)

64 = 64

Here, L.H.S = R.H.S

  • For x = 8 and y = 64

y + 16 = 8(x + 2)

64 + 16 = 8(8 + 2)

80 = 8(10)

80 = 80

Here, L.H.S = R.H.S

Thus, The equation 3 in point-slope from gives the plant's height at any time.

Rearranging equations<br>​
tatyana61 [14]

Answer:Rearrange the equation so that the unknown variable is by itself on one side of the equals sign (=) and all the other variables are on the other side. RULE #1: you can add, subtract, multiply and divide by anything, as long as you do the same thing to both sides of the equals sign.
