Step-by-step explanation:
y-y₁=m(x-x₁)
1-(-4)=m(4-3)
5=m
The domain is all real numbers, reason being, you can put any number for x and get a valid coordinate.
The answer to this is step 2 because they multiplied when they should of subtracted the 10 and the 12.
X/x-2 >= 0 equals x/x >= 0+2 simplified x >=2
Answer:
C = 50p +900
Step-by-step explanation:
Table: (phones, cost) = (0, 900), (1, 950), (2, 1000).
Equation: C = 900 +50p
__
The fixed cost (900) is the "y-intercept" of the equation in slope-intercept form. The cost per phone (50) is the "rate of change" or slope.
