Your answer would be 11a-6 because when you subtract 12a-9a you get 3a and the you add 8a-6 it would equal 11a-6
The linear inequality of the given graph is: D. y < -2x + 3.
<h3>How to Determine the Linear Inequality of a Graph?</h3>
First, using two points on the line, (0, 3) and (1.5, 0), find the slope (m).
Slope (m) = change in y / change in x = (3 - 0) / (0 - 1.5)
Slope (m) = 3/-1.5 = -2.
Next, substitute (x, y) = (0, 3) and m = -2 into y = mx + b to find the value of b.
3 = -2(0) + b
3 = 0 + b
b = 3
Substitute m = -2 and b = 3 into y < mx + b (the shaded part is at the left, so we use the "<" sign)
y < -2x + 3

Answer:
(a) 250º
(b) 310º
Step-by-step explanation:
I've attached an image of how I did it, and now I shall try my best to explain it in words...
A from B:
At B we can extend the line coming from A through the 130º angle.
From A we know that from the vertical, this line has an angle of 70º, so we can split the 130º angle into 70º and 60º.
Now we can extend the vertical at B downwards. This straight vertical line must have angles that add up to 180º. From this we can see that 130º + x = 180º, and x = 50.
Then from the angle rule 'vertically opposite angles are equal', we know that the angle to the left of the downward vertical must be equal to the one opposite and hence must be 70º also.
Now we add these angles up: 130 + 50 + 70 = 250º and this is the bearing to A from B.
B from C:
I've redrawn the triangle just for simplication.
Extend the line at B coming from C, and now using the same angle rule as earlier, we know that that anlge must be equal to the one opposite, which we already worked out to be 50º.
If we drawn a vertical at C, we know that the angle to the left of the vertical must also be 50º since it's made up of the same lines as at B.
Since we're finding the bearing, we now need to find the angle going clockwise: 360-50 = 310º and this is the bearing to B from C
Answer:
10%
Step-by-step explanation:
a simple way to put it is 50 * 2 is 100, 5 * 2 is 10, so 10/100 is 10%
Answer:
65
Step-by-step explanation:
Hi, what you do first is:
P (which stands for perimeter)= L + W + L + W (L stands for length and W stands for width)
P= 16in + 12in + 12in + 25in
P= 28in + 37in (I added 16 to 12 and 12 to 25)
P= 65in.
