5x+2y=12                       5x+2y=12
5x-2y=28                        5(4)+2y=12
                                        2y=12-20
10x=40                              2y=-8
x=40/10                               y=-8/2
x=4                                      y=-4

3. Use trigonometric ratios to solve for the variable. Show your work. Round lengths to the nearest tenth and angles to the near
Lynna [10]

Answer:

x = 3.4

Step-by-step explanation:

recall that for a right angle with an internal angle θ,

cos θ = adjacent length / hypotenuse

in our case,

θ = 55 deg

adjacent length = x units

hypotenuse = 6 units

substitute these into the formula above

cos θ = adjacent length / hypotenuse

cos 55 = x / 6    (multiply both sides by 6)

x = 6 cos 55 (use calculator)

x = 3.4415

x = 3.4  (rounded to nearest tenth)

What is the equation of a horizontal line passing through the point (1, 14)?
Klio2033 [76]
The equation line passing through a point is understood to be parallel to the x-axis. In this case, the equation should be expressed as y = b where b is any number. Since y = 14 in the point (1,14), the equation of horizontal line passing through this point is y = 14.
