the area of a trapezoid can be calculated with the formula A=a+b/2 x h where a and b are the lengths of the bases and h is the hight what is the area of a trapezoid when a=2 b=6 and h=9

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

step-by-step explanation:

35x4=140

140/20=7

the answer would be c:   ax + b = ax + c
