Answer:
5. f(x) = -2x² + 3x
f(-3) = -2(-3)² + 3(-3) = -27
f(2) = -2(2)² + 3(2) = -2
f(-a) = -2(-a)² + 3(-a) = -2a² - 3a
-f(a) = -[-2a² + 3a] = 2a² - 3a
f(a + h) = -2(a + h)² + 3(a + h) = -2(a² + 2ah + h²) + 3a + 3h = -2a² - 4ah - 2h² + 3a + 3h
6. f(x) = 2|3x - 1|
f(-3) = 2|3(-3) - 1| = 2*10 = 20
f(2) = 2|3(2) - 1| = 2*5 = 10
f(-a) = 2|3(-a) - 1| = 2|-3a - 1|
-f(a) = -(2|3a - 1|) = -2|3a - 1|
f(a + h) = 2|3(a + h) - 1| = 2|3a + 3h - 1|
Answer:
24 degrees
Step-by-step explanation:
since BD is an angle bisector, the given numbers are equal to each other
this means that you can write the equation as: 6x = x + 20
subtract x from both sides to move the variable to one side, this leaves you with: 5x = 20
then divide both sides by 5 to find x: x = 4
now substitute this into the value given for angle ABD: 6(4)
this gives you 24 degrees
Answer:
they arrived at 9:20 A.M.
Step-by-step explanation:
If you look at the time they left and how much time it took for them to arrive all you have to do is add 1:45 to 7:35 while adding in time sense so add the 5 to 35 to get 7:40 then add 20 from the 40 to the other 40 to get 8:00 then you can add the remaining 20 to get 8:20 now you can add the hour to make it 9:20 A.M.
