I<br> Tangent Ratio.<br> Find the missing side. Round to the nearest Tenth.
Lemur [1.5K]
Know that:

sin(β)=Opposite/Hypotenuse

Therefore:

sin(54)=x/10

Therefore:

x=10*sin(54)

x=8.1 (To the nearest tenth)

Which equation best represents the line that is parallel to 3x -4y=7 and passes through the point (-4,-2)? Select two options.
katovenus [111]

Answer:

The equation that best represents the line that is parallel to 3x - 4y = 7 and passes through the point (-4, -2)  is y = 3/4x + 1.

Step-by-step explanation:

3x - 4y = 7 and (-4, -2)

First, solve for y in the equation:

3x - 4y = 7

-4y = -3x + 7

4y = 3x - 7

y = 3/4x - 7/4

m = 3/4 (This will be the slope of the parallel line.) and (-4, -2)

Use the point-slope equation to find the equation that will best represent a parallel line:

y − y1 = m(x − x1)

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

y + 2 = 3/4x + 3 (the 4s cancel out)

(3/4 x 4/1 = 3)

y = 3/4x + 1

The graph that I attached is what these two equations would look like graphed. I am not sure what you mean by two options, I'm sorry!
