Answer:

  B(5, 4)

Step-by-step explanation:

The midpoint formula is ...

  M = (A +B)/2

Solving for B gives ...

  B = 2M -A

  B = 2(1, -2) -(-3, -8) = (2+3, -4+8) = (5, 4)

The coordinates of B are (5, 4).

The lifespan of a guinea pig is 6 years less than that of a giraffe. The lifespan of a tiger is 4 times that of the guinea pig.
faust18 [17]
Guinea pig (p) = 4 years old
Giraffe (g) = 10 years old
Tiger (t) = 16 years old

P = g-6
T = 4p

30 = g+g-6+(4(g-6))
30 = 2g-6+4g-24
30 = 6g-30
+30 +30
60 = 6g
6 6
10 = g

P = 10-6
P = 4

T = 4(4)
T = 16

Marina86 [1]

Answer:

neither

Step-by-step explanation:

From 3 to 7 the terms is added by 2 but after 7 the number does not follow the pattern so arithmetic is wrong

from 3 to 5 the terms can be multiplied by 5/3 but after 5 the term doesn't follow the pattern so geometric is out

so the answer is neither ig

The double number line below shows the prices for a certain number of packs of spaghetti at a store. Which statement correctly g
Eduardwww [97]

Answer:

Option B. $72, because the price of each pack is $8

Step-by-step explanation:

Looking at the double number line we have that

The price of 2 packs of spaghetti is $16

The price of 4 packs of spaghetti is $32

The price of 6 packs of spaghetti is $48

The price of 8 packs of spaghetti is $64

To find out he units rate, divide the price by the number of packs

\$16/2=8\frac{\$}{pack}

Find out what is the price of 9 packs of spaghetti

Multiply the unit rate by 9

8\frac{\$}{pack}(9\ packs)=\$72

therefore

The price of 9 spaghetti packs is $72
