Answer:
y(x)=0.8x+2.1
x=12 miles
Step-by-step explanation:
Let x represent the number of miles covered and with a fixed charge of 2.1 irrespective of miles covered then the equation can be written as
y(x)=0.8x+2.1
Substituting y(x) with 11.7 then
11.7=0.8x+2.1
0.8x=11.7-2.1=9.6
X=9.6/0.8=12 miles
Based on the ratios given, the number of people in each service is 8000 in the army, 16000 in the navy and 24000 in the air force.
<h3>What is the number of people in each service?</h3>
Given that 48000 people are in the defence services.
The defence services comprises of the army, navy and air force.
- The defence services are in the ratio 1:2:3
To determine the number of people in each service:
Total ratio = 1 + 2 + 3 = 6
- Number of people in each service = each service ratio/total ratio × 48000
Number in army = 1/6 × 48000 = 8000 persons
Number in Navy = 2/6 × 48000 = 16000 persons
Number in air force = 3/6 × 48000 = 24000 persons
Therefore, the number of people in each service is 8000 in the army, 16000 in the navy and 24000 on the air force.

Answer:
Step-by-step explanation:
<u>Use two pairs of points to work out the equation: </u>
<u>Find the slope:</u>
- m = (5 - 1) / (2 - 1) = 4/1 = 4
<u>Find the y-intercept:</u>
- 1 = 4*1 + b
- b = 1 - 4
- b = - 3
<u>The line is:</u>
Correct choice is D
