The correct answer would be (-24). When multiplying with negative integers, negative times negative is positive, however, the final answer, in this case, is negative because you are then multiplying a positive and a negative:
(-2)(-3)=6
6(-4)=(-24)
I'm guessing Jamar's mistake was he multiplied all of them thinking his answer would be a positive integer: 24.
Answer:
50%
Step-by-step explanation:
if there are 2 sets of 7 marbles each part is worth 50% (them put together is 100%). Therefore you have a 50% chance of getting a red marble
Answer:
<h2>
</h2>
Step-by-step explanation:
x - y² = -1 ⇒ - y² = - x - 1 ⇒ y² = x + 1 {x≥-1}
4x² + 9y² = 72
4x² + 9(x + 1)² = 72
4x² + 9(x² + 2x + 1) = 72
4x² + 9x² + 18x + 9 - 72 = 0
13x² + 18x - 63 = 0 ⇒ a = 13, b = 18, c = -63
Given that the values of sin x and cos x are and
We need to determine the value of tan x.
<u>The value of tan x:</u>
Using the trigonometric identity, the formula for tan x is given by
Now, substituting the values and in the above formula, we get;
Simplifying the terms, we have,
Rationalizing the denominator, we get;
Thus, the value of tan x is
Hence, Option B is the correct answer.
