(1) a =3a-10
(1) 2a =10 

 (1) a = 5and
(2) b = 3(5)(2)
b =  15

Bev earns $2 a week for taking out her neighbor’s trash cans. Complete the table of values. Then state the domain and range.
Eduardwww [97]

Domain : \{1,2,3,4\}

Range: \{2,4,6,8\}

Explanation:

It is given that Bev earns $2 a week.

Thus, for n number of weeks, we shall multiply $2 with n.

Where n=1,2,3,4 is the number of weeks.

For 1 week, Bev earns 2n=2(1)=2 ⇒ $2

For 2 weeks, Bev earns 2n=2(2)=4 ⇒ $4

For 3 weeks, Bev earns 2n=2(3)=6 ⇒ $6

For 4 weeks, Bev earns 2n=2(4)=8 ⇒ $8

Thus, we can see that the domain is the number of weeks.

Hence, Domain : \{1,2,3,4\}

Also, the money earned is the range.

Hence, Range: \{2,4,6,8\}

Tpy6a [65]

Answer:

Area of the sandbox cover = 12 ft²

Step-by-step explanation:

The area of a kite is given as the product of the two diagonals of the kite divided by 2.

Area of kite = (xy/2)

where x and y are the diagonals of the kite.

The sandbox cover, in shape of a kite has a width of 6 ft and a height of 4 ft.

These two dimensions are the diagonals of the kite. Hence, the area of a kite is

A = (6×4/2) = 12 ft²

Hope this Helps!!!
