graphing
What type of function is this: y=mx+b
linear
if y varies directly as x and y=198 when x=22 finds y when x=182. how would you write this equation?
198/22 y/182
Is this an exponential function?
y=2(6%+1)2
yes or no
NO!!!!!!!
find the solution set for :
x+5<20
5,10
What is the point where these two lines cross each other

Micheal breeds chickens and ducks. last month he sold 55 chickens and 25 ducks for $525. This month, he sold 45 chickens and 30 ducks for 530. how would you write this equation
55c+25d=525
45c+30d=530
What is the horizontal asymptote of y=4(2.5)x
y=0
what is the solution set for
2y+6=14

y=-1/9x+3
y=-1/3x+5
what is the equation of the line containing the points (1,3) (5,7) (7,9) (8,10)
y=x+2
the daily cost of hiring a plumber, y, to work x hours on a repair project can be modeled using a linear function. the plumber charges a fixed cost of $80 plus an additional cost of $45 dollars per hour. the plumber works a maximum of 8 hours per day. what is the range of this situations?
80 greater than or equal to Y greater than or equal 440
where do these exponential functions cross
y=-7(1.03)x
y=4(1.4)x-11(0,-7)
How do you solve a solution set.
plug in values in the domain(x) into the equation to get the range(y) value to set an order pair.
what are the 4 types of systems of equation
graphing
table
substitution
elimination
what is the function of
4x+2y=30
y=-2x+15
Joan needed $200 to buy a graphing calculator for her math class. her neighbor will pay her $10 per hour to babysit and her father gives her $30 for owing the lawn. How would you write this inequality?
10x+30 less than or equal to 200
