Let's say that BC is x, so that AB is 4x, and AE = y.
The shaded area then is represented by 4xy/2 = 2xy.
The total area is represented by (4x+x)*y = 5xy.
The fraction of these is 2xy/5xy = 2/5.
Chocolatey107 is right!
Answer:
The answer is on the photo below. Sorry, brainly wouldn't let me type the fraction here for some reason.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
since we're being told to convert the ratio to fraction then it is C. note that 4 ratio is also the same as dividing 4 by 6
f(x)=19x+2→ Switch the f(x) with a y
y=19x+2→ Switch the places of the x and the y variables
x=19y+2→ Solve for y
x−2=19y
y=9x−18
The inverse is f−1(x)=9x−18
