This parabola opens to the left. P. O A. True O B. False

Mathematics
1 answer:
sesenic [268]1 year ago

Answer:

True.

Explanation:

We take the analogy from the graph of y = ax^2

When y = x^2, the parabola opens upward (towards the positive y-axis). However, when the parabola is y = -x^2, it opens downward (towards the negative y-axis).

In a similar way, when we have x = ay^2, the parabola opens towards the positive x-axis ( towards the right). However, if we have x = -ay^2, then the parabola opens towards the negative x-axis ( towards the left).

Therefore, by comparison, x = - 1/8 y^2, opens to the left, and the correct option to choose is 'True'.

Answer: 162.00 or 40.50 or 202.50

Step-by-step explanation:

$6.75 times 30 = 202.50

202.50 times 0.2 = 40.50

Can someone solve this Im to lazy !
Sladkaya [172]
Not impressed that you consider yourself "too lazy" to at least get started on the solution of this problem.  Why not "give it the old college try?"

Start by  choosing letters to represent the unit cost of each popcorn and drink:
p:  popcorn, d:  drink.

Then 2p + 3d = $22.25 and 12p+4d=$39.00
Note that the unit of measurement of all 6 terms here is " $ ".

Solve this system of linear equations simultaneously:

2p + 3d = $22.25
12p+4d=$39.00

In your shoes I would mult. the first equation by -6 and then combine the result with the second equation.  p will temporarily disappear, and you'll be left with an equation in d only, enabling you to find the unit cost of a drink.

Come on.  Show your stuff.  You'll need to respond through Comments.
