Answer:
x = 1
Step-by-step explanation:
When there is a "-" (minus) sign in front of parenthesis, we distribute the sign inside. Let's do this with "-(x+1)". So we will have:
Now, we follow rules of algebra. We take variables to one side and numbers to another side (remember to change signs with changing sides). Shown below:
Now, we add like terms in left side. Such as:
ax + bx = (a+b)x
Thus, we have:
Now, we add right side and divide and get a value for x:
The value of x is 1
Answer:
Population density =
Step-by-step explanation:
The attached figure shows the dimension of an island.
Population density is equal to total population per unit land area.
Firstly we will find the area of the triangle using Pythagoras theorem as follows :
H is Hypotenuse, B is base and P is perpendicular
Area of triangle is given by :
Hence, the population density is .
Answer:
<h2>Step-by-step explanation:
To find f(−1) , substitute the values of x that's - 1 into f(x). That is for every x in f(x) replace it with - 1
That's
We have the final answer as
