This figure is a parallelogram because the opposite sides are congruent. Side CG would become 28 and side BH would also solve out to be 28
Answer:
1) A system of two linear equations to represent this problem
x+y=20 and x-y=12
2) The numbers are x=16 and y=4
Step-by-step explanation:
Let x and y be the two numbers
Given that the sum of the two numbers is 20
That is 
and the difference is 12
That is 
1) A system of two linear equations to represent this problem
2). Noe Solve the system to find the 2 numbers:
Adding the equations (1) and (2) we get
_____________
2x=32
Therfore x=16
Now substitute x=16 in equation (1) we get
Therefore y=4
Therefore the numbers are x=16 and y=4
The graph shown is not a function because points (-1,2) and (-1,0) have the same x value.
Answer:
Below.
Step-by-step explanation:
I can't see the words on your image very well but I can give you an explanation of the remainder theorem.
The theorem allows you to find the remainder of a division without doing the division itself.
You can find the remainder when a polynomial is divided by a linear expression like 3x - 2, for example, using this theorem.
An example will explain the method:
What is the remainder when x^3 - x^2 - 2x - 5 is divided by 2x - 1?
Put 2x - 1 = 0, this gives x = 0.5.
Now we plug x = 0.5 into the polynomial:
This = (0.5)^3 - (0.5)^2 -2(0.5) - 5 = -6.125
So the remainder is -6.125.
The formal definition is
The remainder when P(x) is divided by x - a is f(a).
