Joana takes $20 to the arcade and it costs $2 for every game she plays. a) Write the equation that represents I, how much she has left, after she has played x number of games.
Equation:
b) How much money will she have left is she plays 6 games?
c) If she needs $5 for lunch, will she have enough money to play all 6 games? b)
How much money will she have left if she plays 6 games? c) If she needs $5 for lunch, will she have enough money to play all 6 games?

f(x) = 20-2x

Step-by-step explanation:

f(x) = 20-2x

f(6)=20-2*6=20-12=8

She can get a $5 lunch and still play 6 games, since after 6 games she still has $8.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
