Liz and Andy make money selling jewelry at a local fair. Liz and Andy both sell necklaces for $8 each. Andy also sells bracelets. Andy makes a total of $35 selling bracelets. Use this information for Parts A and B below. PART A: Write an expression that represents the total amount of money Liz and Andy make at the fair if L is the total amount of necklaces Liz sells and A is the total amount of necklaces Andy sells. 8L+8A

PART B: Write a different expression that also represents the total amount of money Liz and Andy make selling jewelry at the fair. Use words and/or numbers to show your work. a=35+8l

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

you have to put the graph on here with the question

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.

the answer for this is 0.25 km. : )
