Law Incorporation [45]

The answer is D: (6, -13)

Step by step:
X is translated 2 units to the right
Y is translated 8 units downs

Substitute 4 for the x value to
Substitute -5 for the y value
( (4) + 2, (-5) - 8 )
4+2=6
-5-8= -13

Name an amount that is NOT a solution to the<br> inequality. Explain how you know.

djyliett [7]

answer: 20

in the number line, you can see that the dot on 20 is an open circle. this means that it is not included. so 20 could be one of the answers.

- anything greater than 20 would be an answer.

Δ ABC is isosceles. If m∠A = 100°, m∠B = (12x + 4)°, and m∠C = (14x - 2)°, find x. A) 1 B) 3 C) 5 D) 7

valkas [14]

Since the sum of the angles of a triangle is 180 degrees, we simply have to add all the angles and equate it to 180 to solve for x. So:100 + 12x + 4 + 14x - 2 = 18026x = 78x = 3
So, x is equal to 3.

If cos θ= 12 /13 and θ is located in the Quadrant I, find sin (2 θ ), cos(2 θ ), tan(2 θ )

Yakvenalex [24]

Answers: sin(2∅) = 120/169, cos(2∅) = 119/169, tan(2∅) = 120/119

<h3>What are trigonometric functions?</h3>

Trigonometric functions are used to establish the relationship between the sides and the angles of a right angle triangle.

Analysis:

If cos∅ = adjacent/hypotenuse = 12/13,

Then, opposite of the right angled triangle = $\sqrt{13^{2} - 12^{2} }$ = 5
