Answer:
The point slope form of this equation would be D) y - 8 = -3/7(x - 5)
Step-by-step explanation:
In order to find this, we simply plug in the information known into point-slope form, which is listed for you below.
y - y1 = m(x - x1)
y - 8 = -3/7(x - 5)
7) (-30x^2 -20)/3x^2-3
8) squareroot(20b+3)
9) (S-d)/2(symbol for pi)×d

Answer:
5.3
Step-by-step explanation:
Use Pyth Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 28
Sq root of 28 = 5.3
To solve for x, we will begin by using the distributive property
6x - 2(x + 4) = 12
6x - 2x - 8 = 12
(always remember to sort your negatives!)
Add like terms
4x - 8 = 12
Add 8 to both sides
4x = 20
Divide both sides by 4
x = 5
