This is the exterior angle theorem meaning the two angles in the triangle is equal to the outer angle of the angle. So you would set your equation to (3x+4) + 58 = 12+8x

Solve for x then plug the x back into the 12+8x equation to get your angle

Find the equation of a line parallel to y - 5x = 10 that passes through the point (3, 10). (answer in slope-intercept form)
s344n2d4d5 [400]
Y - 5x = 10 can be written in the slope-intercept form as
y = 5x + 10

The slope-intercept form is y = mx + b, where m = slope, and b = y-intercept.

In this case, the 5 is the slope.

Parallel lines have equal slopes, so the line we need to find also has a slope of 5. Its equation is

y = 5x + b

We need to find what b is.

We can use the given point, (3, 10), in for x and y and solve for b.

10 = 5 * 3 + b

10 = 15 + b

-5 = b

Now that we know that b = -5, we replace b with -5 to get our equation

y = 5x - 5

42 because it is y = (x - 1) * 1 + 6.

y is the total cost, and x is the amount of visits - 1 because of the six dollar one.
