Answer:
B
Step-by-step explanation:
<em>a/b × d/c = a×d / b×</em><em>c</em>
Multiply the numerators 1st.
x × x = x^2
Next is the Denominator.
x+3 × x+2
now try to multiply each term of the 1st expression with the 2nd.
x × x + x × 2 + 3 × x + 6
x^2 + 2x + 3x + 6
x^2 + 5x + 6
Write the numerator & denominator in their respective places.
x^2 / x^2 + 5x + 6
Answer:
(d) -15
Step-by-step explanation:
Given system of equations are:
Since, given system of equations have no solution.
Answer:
The difference in meaning is that
-3 is a signed value. It lies to the left of zero
+3 is also a signed value, and since it is positive, it lies to the right of zero
|-3| is just the physical distance (left or right) of -3 from zero. Since we live in a physical world, all distances are positive, so its signed value is 3.
Since +3 is also 3 units from zero, |+3| = 3
|-3| = |+3| = 3 since both are three units away from zero.
So, when using absolute values as numbers, rather than distances,
|x| = x if x is not negative
|x| = -x if x is negative
a relation that is not a function
