To do this, add the equations together like this,
3x + 4y = 2 plus
4x - 4y = 12
-x = 14
Multiply the negative sign to both sides because the x cannot be a negative.
x = -14
Now plug in -14 for a x value in one equation, like this to get the y value:
3(-14) + 4y = 2
-42 + 4y = 2
Add 42
4y = 44
y = 11
Your x and y values are:
x = -14
y = 11
Given the inequality;
Let's convert it to slope intercept form;
So, the slope of the line is 2/3 which is positive, and the intercept on the y axis is 4.
C = 2πr
17 = 2(3.14)(r)
17 = 2(3.14r)
17 = 6.28r
6.28 6.28
2.71 ≈ r
The angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.
<h3>
How to calculate the angle?</h3>
It should be noted that the image shows the shooting angles arrangements. Also, π = 180°.
In this case, the value of the angle will be:
= 12π/18
= (12 × 180) / 18
= 12 × 10
= 120°
Therefore. the angle of fire in the standard position will be B. 120°; 2 pi over 3 radians.
