Answer:
I don't understand the question, but...
When you multiply a number by itself, you are squaring it.
<em>For Example:</em>
<em>3 x 3= 9</em>
<em>is the same as...</em>
<em>3^2= 9</em>
Answer:
Lesser x = -7
Greater x = 7

<span>The answers are (-3, -2) (–1, –2) (1, –2) (1, 2).
Let's check out all of the possible solutions.
(-3, -2).
x = -3; y = -2.
y < 0.5x + 2;
-2 < 0.5 * (-3) + 2;
-2 < -1.5 + 2;
-2 < 0.5.
This is correct.
(-2, 1).
x = -2; y = 1.
y < 0.5x + 2;
1 < 0.5 * (-2) + 2;
1 < -1 + 2;
1 < -1.
This is not correct.
(-1, -2).
x = -1; y = -2.
y < 0.5x + 2;
-2 < 0.5 * (-1) + 2;
-2 < -0.5 + 2;
-2 < 1.5.
This is correct.
(-1, 2).
x = -1; y = 2.
y < 0.5x + 2;
2 < 0.5 * (-1) + 2;
2 < -0.5 + 2;
2 < 1.5.
This is not correct.
(1, -2).
x = 1; y = -2.
y < 0.5x + 2;
-2 < 0.5 * (1) + 2;
-2 < 0.5 + 2;
-2 < 2.5.
This is correct.
(1, 2).
x = 1; y = 2.
y < 0.5x + 2;
2 < 0.5 * (1) + 2;
2 < 0.5 + 2;
2 < 2.5.
This is correct.</span>

the answer is d
Step-by-step explanation:
Answer:
The exact value of tan(M) is 5/12 ⇒ answer (C)
Step-by-step explanation:
* Lets revise the trigonometry functions
- In ΔABC
# m∠B = 90°
# Length of AB = a , length of BC = b and length of AC = c
# The trigonometry functions of angle C are
- sin(C) = a/c ⇒ opposite side to ∠C ÷ the hypotenuse
- cos(C) = b/c ⇒ adjacent side to ∠C ÷ the hypotenuse
- tan(c) = a/b ⇒ opposite side to ∠C ÷ adjacent side to ∠C
* Now lets solve the problem
- In ΔONM
∵ m∠N = 90°
∵ MN = 12
∵ ON = 5
∵ tan(M) = ON/NM ⇒ opposite side of ∠(M) ÷ adjacent side of ∠(M)
∴ tan(M) = 5/12
* The exact value of tan(M) is 5/12
