Y=mx+b, m= slope, b= y intercept, plug in. Y=3x+5
Okay, let's represent the price of a bed sheet with 'b' and a towel with 't':
54b + 50t = 923
38b + 61t = 791.50
Now, if we subtract both sides by 54b (on the first equation), we get this:
50t = 923 - 54b
Divide both sides by 50:
t = 18.46 - 1.08b
Now that we know this, we can move on to the 2nd equation:
38b + 61t = 791.50
Input the variable 't':
38b + 61(18.46 - 1.08b) = 791.5
38b + 1126.06 - 65.88b = 791.5
38b - 65.88b = 791.5 - 1126.06
Simplify:
-27.88b = -334.56
Because both sides are negative, we can turn it into a positive:
27.88b = 334.56
b = 334.56/27.88
b = 12
Now that we know that b = 12, we can easily input it into any equation:
648 + 50t = 923
50t = 275
t = 5.5
One bed sheet costs $12 and one towel costs $5.50
Option C is the answer.
Answer:
Exciting
Step-by-step explanation:
The word the person uses like "Bam! Kapow! super energy heros" is all words kids would use when roleplaying and they could get excited.
It would take about 25 months for the cost of leasing a billboard be the same for both companies.

Linear function</h3>
A linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.
