HELP, HELP, HELP Amanda scored 87% on a math test. the following curve shows the results of her whole class. about what percentage of students did Amanda score higher than?

question is incomplete.

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

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
