cos(I), and y =
tan();
=
The amplitudes of y sin(). cos(a) and y = tan(s) are 1.
The graphs of y = sin(s) and y cos(do not have midlines.
The periods of y = sin(x) and y cos(T) are 27, and the period of y = tan(x) is .
Both y = sin(s) and y = tan(s) are increasing on the interval (0, 2) and y cos(t) is
decreasing on that interval.
The domains of y = sin(s), y = cos(I) and y = tan(s) are all real numbers.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this

y -5 = (-1/4)(x + 8)
