Which describes the simpler problems that could be used to solve this problem? paula baked 12 trays of muffins. each tray held 6 muffins. her friend baked 4 trays of 6 muffins. how many more muffins did paula bake than her friend? a. calculate how many muffins each person baked. add the two amounts. b. calculate how many muffins were on each tray. multiply that by the number of trays each person baked. c. calculate how many muffins each person baked. subtract the smaller amount from the larger amount.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
