Answer:
y=2x-1
Step-by-step explanation:
y-y1=m(x-x1)
y-1=2(x-1)
y=2x-2+1
y=2x-1

Answer:
y=4/5x+1
Step-by-step explanation:
y=mx+b
- m is the slope
- b is the y-intercept
m= 4/5
b= 1 (0,1) y-value
Equation:
y=4/5x+1
It's a trick question. There are an infinite number of mixed numbers between 3 and 4 that can multiply to equal 12 (for example, 3 and 3/7 times 3 and 1/2), but there are no mixed numbers between 3 and 4 that can multiply to equal 9. 3 times 3 is not between them but is 3, but that quantity is excluded because 3<x<4. Anything even a small bit above the number 3 would have to be multiplied by 2 and some fraction, which would not be between 3 and 4.
First we will evaluate: ( substitution: u = x² - y², du = - 2 y dy )
=
( than plug in x and 0 )
=
=
= 1/3 x³ ( then another integration )
= 1/3 * 1/4 =
1/12
