Answer:
Distance of point P(3,0) from x axis is zero as this point lies on x axis.
distance of point Q is 3.
Distance of point R is 4.
Distance of point S is 3.
Step-by-step explanation:
Point P already lies on x axis as its y coordinate is zero so its distance from x axis is zero
distance of points Q , R and S is the absolute value of their y coordinates that is 3 , 4 and 3 respectively.
Answer: 286 minutes
Step-by-step explanation:
x : # of months that has gone by
0.24x : cost of the 24 cent plan after "x" minutes
39.95 + 0.10x : cost of the 10 cent plan after "x" minutes
1. 39.95 + 0.10x > 0.24x
2. 39.95 > 0.24x - 0.10x
3. 39.95 > 0.14x
4. 285.36 > x
x must be AT LEAST 286 minutes for plan #2 (39.95 + 0.10x) to be a better deal
Because none of the points on the number line are above 0, we know that the points will be negative.
This eliminates the second and third choices, as they contain positive numbers.
The first point, A, is a number less than -0.5 or -1/2
The first choice matches A with -5/16, which is less than -0.5 or -1/2
Therefore, the fourth choice must be the correct answer.
