Answer:
The mean of x and y is equal to t.
Step-by-step explanation:
Given that,
The mean of t and t+2 is x.
The mean of t and t-2 is y.
i.e.

and

The mean of x and y is :

Hence, the mean of x and y is equal to t.
Answer:
graph?
Step-by-step explanation:
1.D 2. A 3.C 4.D
1 Is the monomial as it only contains one expression.
2. Is the difference of squares because something squared minus something squared.
3. Is standard because it is of the form

4. We know D is the not the monomial simply because its power is negative which means it does not fit the definition of a polynomial.
Answer:
The simple interest is $300.
Step-by-step explanation:
<em>Find the Interest amount.</em>
I: Interest ?
P: Principle Amount $2500
R: Rate 6% = .06
T: Time Period (in years) 2 Years
<em>Convert into equation to find Simple Interest</em>
I = Prt
I = (2500)(.06)(2)
<em>Calculate</em>
I = 300

Answer: R = (4, 5)
Step-by-step explanation: Midpoint is simply the center of a line. So, the equation for it is ((x1+x2)/2, (y1+y2)/2). Hence for this,
x coordinate- (6+x)/2=5
x=4
y coordinates- (9+y)/2=7
y=5
And therefore R is (4, 5)
