Answer: y= -x + 7
Solution:
Step 1 : find the slope using the equation using the pair of coordinates that are given i.e A (−7,14) B (−21,28) ( name them A and B respectively so they can be easily named as x1, y1 and x2,y2 respectively)
m = y2-y1/x2-x1
m = 28-14 / -21 -( -7)
m = 14 / -14
m = -1
Step 2 : Find the y intercept using the line of equation (use and one of the given coordinates either A or B)
Using A ( -7, 14)
y= mx+ b
14 = (-1)(-7) + b
14= 7 + b
14-7 = b
7 =b
So,
y=mx+b
Insert m and b
y= -x + 7
78.2÷0.2 = 390
390 is the answer.
Answer:
How to Conduct a Simulation
Describe the possible outcomes.
Link each outcome to one or more random numbers.
Choose a source of random numbers.
Choose a random number.
Based on the random number, note the "simulated" outcome.
Repeat steps 4 and 5 multiple times; preferably, until the outcomes show a stable pattern
Answer:
11.25
Step-by-step explanation:
7500 times 0.03 times 5 = 1125
1125 divided 100 = 11.25
simple interest formula = Amount times Rate times Time
Divide 100
