here x intercept is -1, so coordinate would be (-1,0)
we use two points (2,7.5) and (-1,0) to find the slope
slope=-7.5/-3 = 2.5
now let us use slope m =2.5 and point (-1,0) to get the y intercept
y=mx+b
0=2.5(-1)+b
b=2.5
plugging value of m and b in slope intercept form to get the equation
y=2.5x+2.5

Answer: x < 0
There is no underline under the "less than" sign
===================================================
How I got this answer:
We have an open hole at 0, and shading to the left. The shading represents all the possible solutions. For example, x = -1 is a solution since it is in the blue shaded region. We can list out the numbers -7, -6, -5, -4, -3, -2, -1 as values in the solution set, but we'd be working forever since there are infinitely many numbers in this set. Also, we'd be excluding fractional and decimal values using this slow method.
As a shortcut, we can just say "any number less than 0 is a solution" which we write as x < 0 or "x is less than zero". We do <u>not</u> include x = 0 itself due to the open hole at 0 on the number line.
Answer:
The profit margin for the concert sponsorship is 31.3725 %
Step-by-step explanation:
An arena receives for 1 event = $1700
An arena receives for 12 events =
An arena receives for 12 events = 20400
The costs for this sponsorship total $14,000
Profit = 20400-14000
Profit =6400
Profit margin =
Profit margin =
Hence the profit margin for the concert sponsorship is 31.3725 %
