Answer:

See attached photo for graph

Step-by-step explanation:

Solve the equation for y... (that means get y by itself)

4y = -5x - 6 (subtract 5x from both sides)

y = -(5/4)x - 6/4 (divide both sides by 4)

y = -(5/4)x - 3/2 (simplify)

Now you can graph using slope-intercept method. The y-intercept is -3/2, and the slope is -5/4

If 3 tan θ = 1, then find the value of sin2 θ –<br> cos2<br> θ.

vfiekz [6]

Answer:

sin2θ - cos2θ = 2sin² θ

Step-by-step explanation:

hello :

tan θ = 1 means : sinθ /cosθ so : sinθ =cosθ

sin2θ = 2sin θ cosθ =2sin² θ

cos2θ = cos²θ - sin²θ = sin²θ - sin²θ =0

sin2θ - cos2θ = 2sin² θ

No solutions, 0

Step-by-step explanation:

When you solve a equation and get an answer of n = s (I am just using n and s a placeholders. They that be any number.) where n ≠ s, then there are no solutions to the equation.
