Step-by-step explanation:
Answer:
Q = -6
Step-by-step explanation:
To find the answer to this, you first must multiply the first function by 2:
2 x (x - 3y = 4)
2x - 6y = 8
Which then means that the second function is the same. This means that to find Q you need to find the number that changed +Qy into -6:
2x - 6y = 8
2x + Qy = 8
The 2x's cancel out, and then remove the equals and the 8:
-6y = Qy
<h3>So Q must be -6</h3>

Inequalities will have a <, >, <=, =>, = or will be worded as "Less than", "greater than", etc.
Equations must have mathematical functions and equal sign.
15=3x is an equation since 3x = 3*x
Finally, expressions are mathematical functions that have no equal signs.

Step-by-step explanation:
The length of the arc is calculated as
AB = circumference of circle × fraction of circle
(11)
AB = 2πr × 
= 2π × 7 × 
= 14π × 
=
π in
(12)
AB = 2πr ×
( r = 20 ÷ 2 = 10 )
= 2π × 10 × 
= 20π × 
=
π
=
π cm
Using the formula for the circumference of a circle:
2 x 100 x 3.14=628ft
