Answer:
x² - x - 12 = 0
Step-by-step explanation:
0 = -x² + x + 12
→ Add x² to both sides
x² = x + 12
→ Minus x from both sides
x² - x = 12
→ Minus 12 from both sides
x² - x - 12 = 0
Make into equation
Y = 1/3x - 2
-5 = 1/3(-1) - 2, false
-1 = 1/3(3) - 2, true
Answer: (3,-1) is also on the line
Use these conversions:
1 foot = 12 in
1 mile = 5280 feet
67000 in * [1 ft /12 in] * [1 mile/5280 ft]
Then the answer is the option c.
Total no. of births = 2000
Births of girls = 64
Birth% of girls
Hence, the number of girls are significantly low.
