Find the slope, if it exists, I the line containing the pair of points. (-8,-2) and (-11,-6)

Answers

Answer 1

Answer: delta y = (-6 - -2) = ( -6 + 2) = -4
delta x = ( -11 - -8) = (-11 + 8) = -3
slope is (delta y)/(delta x) = (-4/-3) = 4/3

Answer 2

Answer: $(-8,-2), \ \ (-11,-6) \n \nFirst \ find \ the \ slope \ of \ the \ line \ thru \ the \ points \: \n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) \n \nm=(-6-(-2))/(-11-(-8)) = (-6+2)/(-11+8) = (-4)/(-3) = (4)/(3)$

Answers

Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.

Jaclyn has 30 times a many apples as her sister he's is has 8 sticker how many stickers does Jaclyn have

Answers

Answer: 22

Step-by-step explanation:

it is 22 because 30-8=22

If Jaclyn has 30 times as many apples as her sister and her sister has 8 stickers, we can find out how many stickers Jaclyn has by multiplying her sister's number of stickers by 30.

Stickers Jaclyn has = 30 * (Stickers her sister has)

Stickers Jaclyn has = 30 * 8

Stickers Jaclyn has = 240

So, Jaclyn has 240 stickers.

Harriet needs to ship a small vase. The box she will use has a volume of 216 inches. If the side lengths are all the same what is the length of each side of the box?

Answers

Volume of the box:
V = a ³ ( a - side length )
a ³ = 216 in³
a = ∛216
a = 6 in
Answer:
The length of each side of the box is 6 inches.

Answer: this is the answer I believe, Volume of the box:

V = a ³ ( a - side length )

a ³ = 216 in³

a = ∛216

a = 6 in

Answer:

The length of each side of the box is 6 inches
