The second choice is correct:
.. Q - P

_____
The constant term is all you really need to look at to figure this.
For P(x), the constant is +2.
For Q(x), the constant is -6.

For P+Q, the constant is -4 . . . . not correct
For Q-P, the constant is -8 . . . . correct
For PQ, the constant is -12 . . . . not correct
For P-Q, the constant is 8 . . . . .not correct

Which of the equations below could be the equation of this parabola?

Mademuasel [1]

Answer:

Option B: $y = -\frac{1}{2} x^2$

Step-by-step explanation:

The parabola has its concavity downwards, so we need a function in the model:

$y = ax^2 + bx + c$

With a negative value of 'a'

The vertex is (0,0), so we have that:

$0 = 0a + 0b + c$

$c = 0$

The x-coordinate of the vertex is given by the equation:

$x\_vertex = -b/2a$

$-b/2a = 0$

$b = 0$

So we have a function in the model:

$y = ax^2$

With a < 0

The only option with this format is B:

$y = -\frac{1}{2} x^2$

Sam works 1/5 hour at the register of a store. He works 2/3 hour in the back stock room and 1/2 hour helping customers. How many

AleksandrR [38]

Answer:

Sam worked $\frac{41}{30}$ hours that day (fractional answer)

Step-by-step explanation:

The total number of hours Sam worked is the sum of all the three hours given.

Let's add the first 2 using LCM and then add that result with the last.

Firstly:

$\frac{1}{5}+\frac{2}{3}\\=\frac{1(3)+2(5)}{15}\\=\frac{13}{15}$

Now,

$\frac{13}{15}+\frac{1}{2}\\=\frac{13(2)+1(15)}{30}\\=\frac{41}{30}$

The hours worked by Sam is 41/30 hours (fractional answer).
