4 0

Step-by-step explanation:

The domain is x. The range is y (or in this case F(x)).

Plug in the numbers in the number set to get a number set for your y.

When the domain is -2:

f(-2) = 2(-2) + 4

f(-2) = -4 + 4

f(-2) = 0

When the domain is -2, the range is 0.

(-2 , 0)

When the domain is 0:

f(0) = 2(0) + 4

f(0) = 0 + 4

f(0) = 4

When the domain is 0, the range is 4.

(0 , 4)

When the domain is 3:

f(3) = 2(3) + 4

f(3) = 6 + 4

f(3) = 10

When the domain is 3, the range is 10.

(3 , 10)

If there are 48 boys and 64 girls and the teachers decided to put them each in in equal rows only boys or girls will be in each

german

Answer: 16

Step-by-step explanation:

The question seeks to know the largest number of people that can sit in each row.

To answer this, find the Highest Common Factor of the numbers 48 and 64.

Factors of 48 ⇒ 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48

Factors of 64 ⇒ 1, 2, 4, 8, 16, 32 and 64

Because the teacher wants the rows to be equal with either only boys or only girls sitting in them, the highest number of people that can sit in a row will be 16.

There will be 7 rows in total.

Boys ⇒ 48/ 16 = 3 rows

Girls ⇒ 64/16 = 4 rows

franklin sold water bottles in two sizes, large ($2.50 each ) and regular ($1 each). He sold 113 bottles altogether and collecte

Ivahew [28]

Let's make a system of equations.

1 large bottle = l
1 regular bottle = r

l + r = 113
221 = 2.5l + r

Isolate r in the first equation and substitute it into the second equation:

l + r = 113
r = 113 - l

---

221 = 2.5l + 113 - l
221 = 1.5l + 113
108 = 1.5l
72 = l

Now, substitute that back into the first equation:

l + r = 113
72 + r = 113
r = 41

Finally, check your work by substituting back into both equations:

72 + 41 = 113 --> 113 = 113 <-- True
221 = 2.5(72) + 41 --> 221 = 180 + 41 <--True

Answer:
Franklin sold 72 large bottle of water and 41 regular-sized bottles of water.
