A line has a slope of - 4 and includes the points (6,v) and (3,3). What is the value of v?
labwork [276]

Answer:  v = - 9


Step-by-step explanation:

Since two points on the line are given, we use formula for slope.

Let (a,b) and (c,d) be two points on the line, the slope of the line is given by

m=\frac{d-b}{c-a}.

Hence, using this we have

-4=\frac{3-v}{3-6}

Thus, we have

-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9

The population of camden, New Jersey has been decreasing by 0.12% a year on average. If this trend continues, and the population
Talja [164]
By the trend that is being given above, the population of New Jersey will only be 99.88% of the population from the previous year. It may be calculated through the following equation,
                               P(n) = P(0) x (1 - r)^n
Substituting the values from the given above,
                                  P(n) = 79,318 x (0.9988)^(2015 - 2006)
                                          = 78465.47
Thus, the population will approximately be 78,466.

How many solutions does this equation have? How do you know?<br><br> 8x +14 - 4x = 9 + 4x - 5
MAVERICK [17]

Answer:

no solutions.

Step-by-step explanation:

8x + 14 -4x = 9+4x -5

8x-4x -4x = 9-5-14

0x = -10

anything multiplied by 0 is 0, so it's impossible to get -10 by multiplying by 0
