Which linear equation has a slope of 3 and a y-intercept of -2?
natka813 [3]

Slope-intercept form:  y = mx + b

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

You know:

m = 3

b = -2        So substitute/plug it into the equation

y = mx + b

y = 3x + (-2)

y = 3x - 2      Your answer is the 2nd option

Explain how to find the exact value of cos(75°).
DanielleElmas [232]

Answer:

\cos(75 \degree)  =  \cos(45 \degree + 30\degree)  \\  \\  =  \cos(45\degree)  \cos(30\degree)  -  \sin(45\degree)  \sin(30\degree)  \\  \\  = ( \frac{1}{ \sqrt{2} } ).( \frac{ \sqrt{3} }{2} ) - ( \frac{1}{ \sqrt{2} } ).( \frac{1}{2} ) \\  \\  =  \frac{ \sqrt{3} }{2 \sqrt{2} }  -  \frac{1}{2 \sqrt{2} }  \\  \\  =  \frac{ \sqrt{3}  - 1}{2 \sqrt{2} }  \\  \\   =  \frac{0.73205}{2.828427}  \\  \\  = 0.2588
