Answer:

9 units²

Step-by-step explanation:

This is a trapezium.

The length of the two parallel lines (on top and bottom) are 5 units and 1 units.

The height of the trapezium is 3 units. Using these information, we can apply the formula for area of trapezium to find the answer.

Area = 1/2 (5 + 1) x 3 = 9 units²

Graph the function g(x) = 1/3 - 4/3x

True [87]

Solutions

g(x) = $\frac{1}{3}$ - $\frac{4}{3}$ x

 g(x) = - $\frac{4}{3}$ x + $\frac{1}{3}$

x = -5

= g(x) = - $\frac{4}{3}$ × (-5) + $\frac{1}{3}$

= $\frac{20}{3}$ + $\frac{1}{3}$

= $\frac{21}{3}$

= 7

(-5,7)

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡

x = 7

 = g(x) = - $\frac{4}{3}$ × (7) + $\frac{1}{3}$

= $\frac{-28}{3}$ + $\frac{1}{3}$

= $\frac{-27}{3}$ = -9

(-7,9)

x = (-7,9) y = (-5,7)
