7x-6=85
Add 6 to both sides
7x=91
Divide both sides by 7.
x=13

hope this helps.

Is each line parallel, perpendicular, or neither parallel nor perpendicular to a line whose slope is −34?
Zigmanuir [339]

Given:

The slope of a line is -\dfrac{3}{4}.

To find:

The lines in the options are parallel, perpendicular or neither parallel nor perpendicular to the given line.

Solution:

We know that the slopes of parallel lines are equal.

The slope of line Q and the slope of given line are same, i.e., -\dfrac{3}{4}. So, the line Q is parallel to the given line.

The slope of a perpendicular line is the opposite reciprocal of the slope of the line because the product of slopes of two perpendicular lines is -1.

The slope of a line is -\dfrac{3}{4}. It means the slope of the perpendicular line must be \dfrac{4}{3}. So, the line N is perpendicular to the given line.

The slopes of line M and P are neither equal to the slope of the given line nor opposite reciprocal of the slope of the line.

Therefore, the lines M and P are neither parallel nor perpendicular.

Since x is across from 148, and arcs opposite inscribed angles = 2×angle, then we can find x first.
We could set the 2 angles equal to 180 or their arcs equal to 360.
360 - (2×148) = x-arc
x-arc = 360 - 296 = 64
x = x-arc ÷2 = 64/2 = 32
Now for angle A we plug in for x:
A = 2x+1 = 2(32)+1 = 65°
