Which method do you prefer: the slope-intercept form y = mx + b or the point-slope form y - y1= m(x - x1)? explain in a brief paragraph why you prefer that method over the other.

Step-by-step explanation:

y=mx + b is easier to solve for when you need to find slope intercept form. If you have your y and mx you can figure out what your b is.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
