The function f(x) is graphed on the coordinate plane.

what is f(−4) ?

enter your answer in the box.

f(−4) =
graph of a line on a coordinate plane. the horizontal x axis ranges from negative 5 to 5 in increments of 1. the vertical y axis ranges from negative 5 to 5 in increments of 1. a line passes through the points begin ordered pair 0 comma 2 end ordered pair and begin ordered pair 4 comma 0 end ordered pair.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
