Can anyone help me with this? I need to prove that line BE bisects angle DBC

angle CBE = angle EBD

Step-by-step explanation:

Angles CAB and BCA are equal because their opposite lengths are equal

angle CBE = angle BCA

(Alternate angles)

angle EBD = angle CAB

(corresponding angles)

Since angles CAB and BCA are equal,

angle CBE = angle EBD

Which means BE divides the angle DBC into two equal angles. Hence BE bisects the angle DBC

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
