Which equation can be used to find the answer?
after two months, rachel has saved enough money to buy an mp3 player. during the second month, she saved $87 and she pays $199 for the mp3 player.
how much did rachel save during the first month?
a.
m = 87 • 2
m = 174
$174
b.
199 + 87 = m
m = 286
$286
c.
m + 87 = 199
m = 112
$112
d.
m – 87 = 199
m = 287
$287

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.
