What is the area of the figure below ?

c

Step-by-step explanation:

large rectangle is 8x10=80cm^2

small rectangle is 2x3=6cm^2

the area is thus 80-6=74cm^2

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

you can't solve x because it is 2 linear equation and you only have one equation
