Answer:
s = -1
Step-by-step explanation:
7 = -10s - 3
==> add 3 to both sides
10 = -10s
==> divide both sides by -10
-1 = s

Answer:
No
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y = 3x - 7 is in this form
with y-intercept c = - 7
Answer:
30 degrees
Step-by-step explanation:
The things we do have and want to find are as follows:
- We know that this is a right triangle, and one angle is 90 degrees
- We want to find an angle
- Relative to that angle, we are given an adjacent side as well as the hypotenuse
One equation that encompasses this is cos(θ) = adjacent/hypotenuse, so
cos(m∠H) = 10√3 / 20
For an equation of form cos(x) = y, we can say that arccos(y) = x. Therefore, we can write our equation as
m∠H = arccos(10√3 / 20)
m∠H = 30 degrees
