A rational number is<em> a number which can be written a ratio of two integers</em>.
In decimal form, a rational number is any number which either <em>terminates </em>or <em>repeats</em> after the decimal point. Since -1.987 terminates after the 7, it <em>is</em> a rational number.
The coordinates of S would be (4, 4)
In order to find this, we need to know that the value of midpoint (M) points will always be the average of S and T's points. This is because it is the midpoint. Therefore we can use the following formula.
Value of x
(S + T)/2 = M
(S + 0)/2 = 2
S + 0 = 4
S = 4
Then we can do the same for the y values
Value of y
(S + T)/2 = M
(S + 6)/2 = 5
S + 6 = 10
S = 4
Answer:
(5x^2-3) +(2x^2-3x^3)
=3x^3+5x^2+2x^2-3
= 3x^3 +7x^2 -3
Step-by-step explanation:
hope this is correct cuz I'm not an expert...
