Answer:
r = -1 or r = 5/3
Step-by-step explanation:
(2k - 1)/(k + 1) = (3k + 1)/(2k - 1)
(2k - 1)^2 = (k + 1)(3k + 1)
4k^2 - 4k + 1 = 3k^2 + 4k + 1
k^2 - 8k = 0
k(k - 8) = 0
k = 0 or k = 8
For k = 0,
(2k - 1)/(k + 1) = -1/1 = 1
For k = 8,
(2k - 1)/(k + 1) = 15/9 = 5/3
Answer:
Assuming that
is a diameter.
Given that 
And that point O is the center of the circle

Explanation:
Because angle AOB is subtended by arc AB from point O.
Arc AB is equal to the measure of that angle.
Since arc ABC is subtended by the diameter, the arc is 180°.
To find out how much he makes per week, take the amount and divide it by the week.
1520/4=380.
He makes 380 per week.
Answer:
infinite solution/all real numbers
Step-by-step explanation:
x+6+5x=6(x+1)
Step 1: Simplify both sides of the equation.
x+6+5x=6(x+1)
x+6+5x=(6)(x)+(6)(1)(Distribute)
x+6+5x=6x+6
(x+5x)+(6)=6x+6(Combine Like Terms)
6x+6=6x+6
6x+6=6x+6
Step 2: Subtract 6x from both sides.
6x+6−6x=6x+6−6x
6=6
Step 3: Subtract 6 from both sides.
6−6=6−6
0=0
so it is infinite solution/all real numbers
