Answer: 14

Step-by-step explanation:

Step 1: Graph both equations to find the vertices (see attached):

The graph shows vertices at: (0, 0), (3, 0), (0, 5) and (2, 3)

Step 2: Input the coordinates of the vertices into the given function (c = 4x + 2y):

(0, 0): 4(0) + 2(0) = 0
(3, 0): 4(3) + 2(0) = 12
(0, 5): 4(0) + 2(5) = 10
(2, 3): 4(2) + 2(3) = 14

Step 3: Evaluate the value from Step 2 to find the maximum (largest).

the largest value between {0, 12, 10, 14} is 14

Sheila is going to divide a 38-inch piece of ribbon into 5 equal pieces. She says each piece

DENIUS [597]

Sheila is incorrect! I think what she did is think the 38 was actually a 35, which WOULD of made her statement true, but since it's 38, she's very incorrect. Sheila should be using the quotient for the size of each piece. 38 divided by 5 is 7.6. The correct answer is 7.6 inches.

Answer:

*read explanation for both questions*

Step-by-step explanation:

So the first one asks ”the first number in a pattern is 6, the pattern follows the rule ’multiply by 4’ “

The question has the answer to it, so each number would be multiplied by 4. So we have the first one which is 6, next we multiply 6 x 4 = 24. Then we multiply 24 x 4 = 96. and finally you multiply 96 x 4 = 384.

That’s the pattern fo the first one

The second one asks “The shapes have been sorted into two groups. explain what attribute was used to sort the shapes.”

When we’re looking for attributes, look for what they have in common. For me, I see that Group 1 has the smaller versions of the same shapes in Group 2. So that could be the attribute the question is asking for.

Dwayne's family has many pets. at the house they have both cats and birds. between all the cats and birds, they have 16 eyes and

densk [106]

Let C be the number of cats and B be the number of birds.
Each cat has 4 legs while each bird has 2 legs. Thus,
4C + 2B = 22
2B = 22 - 4C

Each cat and each bird has 2 eyes
2C + 2B = 16
Substituting 2B
2C + 22 - 4C = 16
2C = 6
C = 3
2B = 22 - 4(3)
B = 5

2 cats and 5 birds

Brooke has to set up 70 chairs in equal rows for the class talent show. But, there is not room for more then 20 rows. What are t

grin007 [14]

Answer:

The answer is 2, 5, 7, 10, and 14.

Step-by-step explanation:

Let x be the number of rows. There is not room for more than 20 rows:

x ≤ 20

Since all rows must be equal, when we divide 70 by x, we must get a whole number. So, we must find all divisors of 70 smaller or equal to 20 and they are: 2, 5, 7, 10, and 14.

So, the possibilities are:

2 rows with 35 chairs in each row

5 rows with 14 chairs in each row

7 rows with 10 chairs in each row

10 rows with 7 chairs in each row

14 rows with 5 chairs in each row

Hope this helps!!
