8x - 2y = 48, y =4
8x - 2(4) = 48
8x - 8 = 48
8x = 48+8
8x = 56
x = 56/8 = 7
x = 7
Answer:
The angle complies with the state regulations.
Step-by-step explanation:
The angle of elevation is the angle in the figure, and from trigonometry we find that
taking the inverse sine of both sides we get
which gives
which is less than 5°, and therefore is well within the state regulations.
Slope intercept: y=-3/4x+2
The rule would be : 3^x, where x starts at 0.
3^0 is 1,
3^1 is 3, because 3 one time is 3.
3^2 is 9, because 3x3 is 9.
3^3 is 27, because 3x3x3 is 27
Answer: 3^x
