Given the central angle, name the arc formed. ∠GQJ arc circle 13 A. FHˆ B. IJˆ C. GJˆ D. GQJˆ

Vaselesa [24]

The name of the arc formed by the central angle ∠GQJ is (c) GJ

The central angle is given as:

∠GQJ

The above means that the center of the circle is located at point Q.

When the point Q is removed from the name of the central angle, we have points G and J

These represent the endpoints of the arc.

Hence, the name of the arc formed by the central angle ∠GQJ is (c) GJ

≠A student took a system of equations, multiplied the first equation by and the second equation by , then added the results toge

Mandarinka [93]

Answer:

C. 3x+6y=9 and-2x-4y=4

Step-by-step explanation:

Given

Steps:

Multiply equation 1 by 2

Multiply equation 2 by 3

Add the results together

The attachment completes the question

(a): -2x+4y=4 and -3x+6y=6

Multiply by 2: $-2x+4y=4 ===> -4x + 8y = 4$

Multiply by 3: $-3x+6y=6 ===> -6x + 12y = 12$

Add together

$-4x - 6x + 8y + 12y = 4 + 12$

$-10x + 20y = 16$

B. 3x+y=12 and -3x+6y=6

Multiply by 2: $3x+y=12 ===> 6x + 2y = 24$

Multiply by 3: $-3x+6y=6 ==> -9x + 18y = 18$

Add together:

$6x - 9x + 2y + 18y = 24 + 18$

$-3y + 10y = 42$

C. 3x+6y=9 and-2x-4y=4

Multiply by 2: $3x+6y=9 ===>6x + 12y = 18$

Multiply by 3: $-2x-4y=4 ===> -6x - 12y = 12$

Add together:

$6x - 6x + 12y - 12y = 18 + 12$

$0 = 30$

This is the equation the student could have used because 0 = 30 means the equation has no solution.

Firdavs [7]

When you have expressions with a power to another power, you multiply the powers together.
$( n^{6})^{3} = n^{6*3}= n^{18} \\ Your\ answer\ is\ A$

Can you help me find the side??? It's trigonometry!!

olganol [36]

Answer: 5.6

===================================

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(B) = AB/BC

cos(62) = AB/12

12*cos(62) = AB

AB = 12*cos(62)

AB = 5.63365875

AB = 5.6
