With mathematical connections write an expression for the length of the segment

PR = 13y +25

QR = 5y+20

Step-by-step explanation:

For figure a.

AB = x+2

BC = 7x-3

AC and AB + BC coincides with each other, so they should be equal

i.e AC = AB + BC

{ We know that things which coincide with each other are equal }

Therefore,

AC = AB + BC = ( x+2 ) + ( 7x-3 ) = x+2+7x-3 = 8x-1

For figure b.

PQ = 8y + 5

PR = 13y +25

PR and PQ + QR coincides with each other , so they should be equal

i.e PR = PQ + QR

{ We know that things which coincide with each other are equal }

Therefore,

PR = PQ + QR

QR = PR - PQ

QR = ( 13y +25 ) - ( 8y + 5 )

QR = 13y+25-8y-5

QR = 5y+20

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
