Answer:
b=7
Step-by-step explanation:
7 squared is 49, so b equals 7. I hope that was what you were looking for, and that it helps.
Use the slope-intercept form y=mx+b
Answer:

Step-by-step explanation:
Given: trapezoid RSTU with vertices R(-1, 5), S(1, 8), T(7, -2), and U(2, 0).
Plot these points on the coordinate plane. As you can see, lines RU and ST are parallel lines and segments ST and RU are bases of the trapezoid.
The median of the trapezoid (the middle line) passes through the midpoints of the sides RS and TU. Find these midpoints:

The equation of the line MN is

Answer:

Step-by-step explanation:
We want to find the x-intercepts of

At x-intercept, y=0.


Take sine inverse of both sides to get:


The x-intercepts are:

for n being an integer
