1. Jason is closing the register at the end of the day. He is in charge of counting all the change. There are 129 coins counting only quarters and dimes. If Jason counts
$27.00 in these coins, how many quarters(x) and dimes(y) are there?
Solve the system of equations to find the answer.
x + y = 129
.25x + .10y = $27.00
a. x = 100, y = 29
b. x = 70, y = 95
c. X = 94, y = 35
d. x = 150, y = 15

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
