Answer:
D) y = 3x-2
Step-by-step explanation:
The y-intercept is (0,-2). This means that in y-mx+b, b is going to by -2. We know the slop is 3 because if I choose 2 points and move ONE unit to the right, it is increasing by 3. Also, you can do y1-y2/x1-x2, or y2-y1/x2-x1.
Please tell me if this is wrong and hope this helps :)
Answer:
D=0.031746
Step-by-step explanation:
Isolate the Variable by dividing each side by Factors that don't contain the Variable.
In this question, you are given Beth velocity(8mph) and Brandon velocity(12mph). To answer this question, you will need to find the initial distance of Beth and Brandon. The calculation would be:
Initial distance= Beth velocity * duration= 8 mph * 15 minutes * hour/60 minutes= 2miles
After that, the calculation would be:
beth_velocity * time + initial distance = brandon_velocity * time
8mph * time + 2 miles= 12 mph* time
4mph * time = 2 miles
time= 2 miles / 4 mph= 1/2 hour = 30 minutes
The two requirements for a proportional relationship are: The ratio of the two variables maintain the same ratio.
M=4a+2c
a=10
c=5
m=4*10+2*5=40+10=50
Answer: 50
