Solve for r using factoring:
Solve for r:
r^2 - 8 r - 33 = 0
The left hand side factors into a product with two terms:
(r - 11) (r + 3) = 0
Split into two equations:
r - 11 = 0 or r + 3 = 0
Add 11 to both sides:
r = 11 or r + 3 = 0
Subtract 3 from both sides:
Answer: r = 11 or r = -3
Answer:
C
Step-by-step explanation:
= 6 ( multiply both sides by 3x to clear the fraction )
15y - 10 = 18x ( add 10 to both sides )
15y = 18x + 10 ( divide terms by 15 )
y = 
x + 
, that is
y = 
x + 
→ C
The probability of drawing both without replacing either is :
14/41 * 12/40 = 7/41 * 3/5 = 21/205
The probability of drawing both WITH replacement is:
14/41 * 12/41 = 168/ 1681
Exact form is 25/2
Decimal form is 12.5
Mixed number form is 12 1/2
Answer:
154000
Step-by-step explanation:
2: 2 * 2 * 2 * 2 = 16
5: 5 * 5 * 5 = 125
7: 7
11: 11
composite number := 16 * 125 * 7 * 11 = 154,000
