Consider the function       3 2 f x x x x 3 10 13 20 . (a) determine the x-intercepts of f x  . (b) determine the y-intercept of f x 

slope is 35 and 20 miles is the y-intercept.

step-by-step explanation:

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
