Two runners are saving money to attend a marathon. The
first runner has $112 in savings, received a $45 gift from a
friend, and will save $25 each month. The second runner
has $50 in savings and will save $60 each month
Which equation can be us
. months it will take for both
amount of money?
112 - 25m + 45 = 50 -
112 + 25 + 45m = 50m
112 + 25 – 45m = -50m
0 112 + 25m + 45 = 50 + 60

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
