The evening walk is shorter because 3/6 is 1/2 or .5 a mile, while 2/3 mile is .66 a mile
(81m^6)^1/2 = (3^4*1/2) (m^6*1/2) = 3²m³
Answer:
(- 2, 15 ) and (2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 3x² - 2x - 1 → (1)
2x + y = 11 → (2) ← subtract 2x from both sides
y = 11 - 2x → (3)
Substitute y = 3x² - 2x - 1 into (3)
3x² - 2x - 1 = 11 - 2x ( subtract 11 - 2x from both sides )
3x² - 12 = 0 ( add 12 to both sides )
3x² = 12 ( divide both sides by 3 )
x² = 4 ( take the square root of both sides )
x = ±
= ± 2
Substitute these values into (3) for corresponding values of y
x = - 2 : y = 11 - 2(- 2) = 11 + 4 = 15 ⇒ (- 2, 15 )
x = 2 : y = 11 - 2(2) = 11 - 4 = 7 ⇒ (2, 7 )
AB and CD are interesting lines
Therefore, the angles formed will be equal (vertically opposite angles).
Hence,

Now,





Its A (1,2) yo you should look for a graphing calculator it helps alot all you need is to put that exact equation in and it graphs for you
