Line j passes through points (-6,1) and (-3,6) .line m is parallel to line j and passes through point (15,-1). what is the equat
Vikentia [17]
Slope of line j;
m=\frac{change in x}{change in y}
m=\frac{6-1}{-3--6}
m=\frac{5}{3}
Parallel lines have equal gradients;
So, 
y=mx+c
y=5/3x+c
Replacing for x and y;
-1=5/3(15)+c
-1=25+c
c=-26
y=\frac{5}{3} x-26

Need help step by step plz

I'm assuming D is the center of the circle.  See the new figure.

Angle BDC = 106 degrees, that's the definition of arc measure.

Triangle BDC is isosceles (two radii make congruent sides) so the two remaining angles in BDC are equal, DBC=DCB=(180-106)/2=37 degrees.

Angle BAC = 106/2 = 53 degrees, subtending the arc of 106 degrees.

Angle CAD = 53/2 = 26.5 degrees because AD is a bisector, the shared hypotenuse of congruent right triangles AED and AFD.

AFD is also congruent to CFD, so angle DCA is also 26.5 degrees

Angle ACB is the sum of DCA and DCB, ACB = 26.5 + 37 = 63.5 degrees

The angle subtends the arc we seek, whose measure must be double:

10x - 23 = 2(63.5) = 127 degrees

10x = 150

x = 15

Readme [11.4K]
Hmm... I would say the equation would look like 3+5x=72/4. 
3+5x=72/4
3+5x=18
5x=18-3
5x=15
x=15/5
x=3

The number is 3
