Answer: OPTION B.
Step-by-step explanation:
Given the following equation:
These are the steps to solve it:
<em>Step 1</em>
Add like terms on the left side of the equation:
<em>Step 2</em>
Apply Addition property of equality, which states that: 
Then, we can add 25 to both sides of the equation:
<em>Step 3</em>
Applying the Subtraction property of equality, we can subtract 
from both sides:
<em>Step 4</em>
Applying the Division property of equality, we can both sides of the equation by 3. Then:
Answer:y-3=-3/4(x+8)
Step-by-step explanation: you plug the numbers into the formula y-y1=slope(x-x1)
If i can remember, a direct variation is y=kx so find y and x, and you can figure out k. i’m probably wrong, good luck tho! lol
Answer:
4.647 to the nearest thousandth.
Step-by-step explanation:
The formula for the length of an arc between x = a and x = b is
a
∫ √( 1 + (f'(x))^2) dx
b
Here f(x) = √x so
we have ∫ (√( 1 + (1/2 x^-1/2))^2 ) between x = 0 and x = 4.
= ∫ ( √( 1 + 1/(4x)) dx between x = 0 and x = 4.
This is not easy to integrate but some software I have gives me the following
length = √17 + 1/8 log(33 + 1/8 √17)
= 4.647.
