Answer:

x/3 -3= 18 (add three to both sides)

x/3= 21

x/3(*3) =21(*3) (multiply by 3 on each side to cancel out the division)

x= 63

63/3-3=18

21-3=18

18= 18 (checking answers)

Anna [14]

Answer:

in the attachment

Step-by-step explanation:

Given: Piece-wise function graph.

We need to find the function.

In the graph, we can see a two-piece

For -3≤x≤0

Endpoints on graph (-3,-6) and (0,0)

It is the horizontal line. The equation of the horizontal line is y=k.

Equation: y=3

Now, we write as a piecewise function.

First blank = 2x

Second Blank = 3

hope this helps:)

Please help and thank you! Will mark whoever answers right the brainliest!
laila [671]

Answer:

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)
