The constant of proportionality is: 0.2 and the equation is: c = 0.2t
Step-by-step explanation:
Let t be the number of texts and c be the cost
Then according to given statement
c ∝ t
The proportionality symbol will be removed and a constant f proportionality will be introduced.
<u>For constant of proportionality:</u>
Hence the constant of proportionality is 0.2

The dance would /cost/ the school 50 dollars, making the profit -50. The dance tickets make 300, and the DJ takes away 250, making a 50 profit. However, the decorations cost 100, taking away that from 50, making -50.
The answer is A, 297. I spent 10 minutes on this trust me
Answer:
x= 2,
,y = 5
Step-by-step explanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 5
// Plug this in for variable y in equation [2]
[2] -4x + 2•(5x-5) = 2
[2] 6x = 12
// Solve equation [2] for the variable x
[2] 6x = 12
[2] x = 2
// By now we know this much :
x = 2
y = 5x-5
// Use the x value to solve for y
y = 5(2)-5 = 5
Solution :
{x,y} = {2,5}
For this problem the work would look like this:
Multiply -2 to both sides to isolate w.
Notice that the sign flips! This is because anytime a negative numbers transfers to the other side of the inequality the inequality flips directions.
Now this should be the solution once solving.
The attached picture below shows the graph.
Hope this helps!
