Make a function machine for the expression 10-5x use it to find ordered pairs x=3, x= -y, x =0.25, and x= 3/4

Step-by-step explanation:

We assume that "make a function machine" means to program a spreadsheet or calculator to calculate values of the function for different inputs. Just about any graphing calculator or spreadsheet is a suitable platform. Attached is a screeenshot using the free Desmos online graphing calculator.

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
