The answer is x=2+5i or 2-5i
31-27+12-23-(-25)+(-6)= 12
Answer:
x=number of hours
c(x)= 25x+75
y-intercept= (0, 75)
Equation= y=25x+75
Slope= 25
Step-by-step explanation:
75 would be the y intercept(constant) because that's the initial charge for a call.
25 would be the coefficient for x because the hour you spend on the call varies.
The slope is how steep the line is, in this case it is 25.
x is the number of hours because that is the time that varies.
Answer:
X = 40
Explanation: (2x) = 80
80/2 = 40
X = 40 degrees
200+90+8+.02 is the correct answer
