A photograph in a catalog has a scale of 2 in: 5 ft. A tent in the photograph is 3 inches long.
How long is the tent?
A) 7.5 ft
B) 8 ft
C) 8.5 ft
D) 9 ft

7.5 ft

Step-by-step explanation:

divide 5 by 2 -- 5 ÷ 2 = 2.5

now multiply 2.5 by 3 -- 2.5 × 3 = 7.5

the balance is found at the link

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
