What is the function equation for the input/output table? x y
0 0
1.3 3.9
5 15
8 24

y = (3.9) x

y = x + 3

y = 3 x

y = x + 3.9

if you was gonna solve for a, a is a   < -12

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16

answer is  

a.

7 in. x 11 in.

hope you get this right.
