So the graph shows the cost of the phone call on the y-axis and the length of the phone call on the x-axis.
The question ask is what is the least expensive per minute.
So your equation is cost/time.
Then you plug in the values of each point.
w=$1.25/2 minutes
x=$2/5 minutes
y=$2/10 minutes
z=$2.50/10.5 minutes
Solve each question-
w=0.63 (rounded)
x=0.4
y= 0.2
z=0.24 (rounded)
These values show the cost per minute of each point. So, in order the answer the question which one cost the least per minute you would select the lowest value answer from the question of each point. Which would be y.
1) <span>-3, 6, -9, 12...
f(2) = -2*6 - (-3) = -9
f(3) = -2*-9 - (6) = 12
2) </span><span>2) Choose the slope-intercept equation of the line that passes through the point (-2, 2) and is parallel to y = 4x + 7.
Slope equals 4, since it's parallel. Substituting...
2 = 4*-2 + b Add 8 to both sides
10 = b
y= 4x + 10
3)Question is poorly transcribed, but assuming the points are (10, 60) and (16, 96):
Average rate of change = (96-60) / (16-10) = 36 / 6 = 6m/s.
4) A slope of zero means that y does not change with x. This means y is the same for any x value, so y is a horizontal line.
The third graph, the one where y= -6, is the correct answer.

Answer:
All numbers greater than 5, i.e., 
.
Step-by-step explanation:
The given inequality is
Isolate variable terms on one side to find the solution.
Subtract 50x from both sides.
Divide both sides by 30.
It means, all the numbers which are greater than 5, are the solutions of the given inequality and 5 is not included in the solution set.
Answer:
Total amount pay after 3 week = $147.5
Step-by-step explanation:
Given:
Amount of loan taken = $125
Amount interest per $100 = $6 per week
Find:
Total amount pay after 3 week
Computation:
Amount of interest per week = 125[6/100]
Amount of interest per week = $7.5 per week
Amount of interest in three week = 3 x Amount of interest per week
Amount of interest in three week = 3 x 7.5
Amount of interest in three week = $22.5
Total amount pay after 3 week = Amount of loan taken + Amount of interest in three week
Total amount pay after 3 week = 125 + 22.5
Total amount pay after 3 week = $147.5
