There are 2 ways of measuring angle. It is either by radians or by degree. Radians is unitless or we just call it rad. A pi is equivalent to 180 degrees. A pi is equal to 3.14. So when we answer this we multiply 216 by pi/180 or 2pi/360. The answer is 3.7699 or 3.8 rad.
Y = x - 7 ---------- (1)
5x + 2y = 7 ------ (2)
Sub (1) into (2):
5x + 2(x -7) = 7
5x + 2x - 14 = 7
7x - 14 = 7
7x = 7 + 14
7x = 21
x = 3 ----- -sub into (1)
y = x - 7
y = 3 - 7
y = -4
Ans: x = 3, y = -4
Answer:
b=16
Step-by-step explanation:
75%=75/100=3/4
3/4*b=12
b=12/1*4/3
b=16

Answer: Choice B</h3>
Explanation:
Notice that the jump from y = 9 to y = 10 is +1
But the jump from y = 10 to y = 12 is +2
This is sufficient info to say that the rate of change is <u>not</u> constant. The change in y must be the same.
If you were to plot these points on the same xy grid, then you could see that it's impossible to draw a straight line through all four points.
