Answer:

Step-by-step explanation:

XY=ST/2

3z+2=(7z-1)/2

2*(3z+2)=7z-1

2*3z+2*2=7z-1

6z+4=7z-1

+1 +1

6z+5=7z

-6z -6z

5=z

Does this image have a set of inputs to a set of possible outputs where each input is related to exactly one outputs Yes or No?

borishaifa [10]

Answer: Yes

This graph passes the vertical line test. This is a test where we try to draw a single vertical line through more than one point on the curve. In this case, such a thing is not possible. Any input x leads to exactly one output y. This graph is a function.

Need help ASAP to this math question about how many gallons it will take to fill a pool

NARA [144]

1 cubic foot = 7.48 gallons

hence
$\frac{7.48 gal}{1 ft^3} =1$

unit conversion
$\frac{3000 ft^3}{} \times \frac{7.48 gal}{1 ft^3} = 3000 \times 7.48 gal$

3000 x 7.48 =22440
