Answer:
x and y are directly related because y = -3x
Step-by-step explanation:
Answer: is the linear equation.
yes, it is possible.
Step-by-step explanation:
given data:
we were told that she would make $20 for each 5K participant and $45 for each 10K participant.
cost of each 5k participant = $20
cost of each 10k participant = $45.
her target = $9500
<u>solution:</u>
<em>let y represent the </em><em>10k</em><em> </em>
let x represent the 5k participant
the linear equation for this scenarios is
(b.) possibility of having 220 participant in the 5k race.
