Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Which conic section is represented by the following equation? 9x^2 – 5x – 3y^2 – 2y + 4 = 0
Answer:
D. Hyperbola
Step-by-step explanation:
I put B but it was wrong
D is the right answer
The given equation is represent a ''Hyperbola''.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ 9x² - 5x - 3y² - 2y + 4 = 0
Now, We know that;
The standard form of the equation is,
⇒ ax² + by² + 2gx + 2fy + 2hxy + c = 0
For Hyperbola, The condition is,
⇒ h² > ab
For Ellipse , The condition is,
⇒ h² < ab
Here, We have;
⇒ h = 0
⇒ a = 9
⇒ b = - 3
⇒ ab = 9 x - 3 = - 27
⇒ h = 0
Hence, We get;
⇒ 0 > - 27
⇒ h² > ab
Thus, This equation is represent a ''Hyperbola''.

An item is on sale for $56. If this price represents a 25% discount from the original price, what is the original price?
9514 1404 393
Answer:
$74.67
Step-by-step explanation:
Let p represent the original price. Then the relation is ...
$56 = p - 0.25×p
$56 = 0.75p
$56/0.75 = p ≈ $74.67
The original price was $74.67.

What is the surface area of this rectangular pyramid?
Answer:
i believe the answer is 266.08
Step-by-step explanation:
Which of the following is the solution set of x2 + 8x + 12 = 0?
(-2.-6
2.6
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.

how do you know how many solutions are possible for a system of equations
Answer:
Step-by-step explanation:
If the slopes are the same but the y-intercepts are different, the system has no solution.
If the slopes are different, the system has one solution.
If the slopes are the same and the y-intercepts are the same, the system has infinitely many solutions.
Answer:
Step-by-step explanation:
If you mean linear systems. If lines have a different slope there will be one solution. If they have the same slope (parallel) and a different y intercept there are zero solutions. If they have same slope and y intercept than they are the same line and have an infinite number of solutions.

Solve for X:
5x - 14 = 8x + 4
a X = -6
b
X = 10/3
c
X = 6
d
X = -18/13
Answer:
a) x = -6
Step-by-step explanation:
5x - 14 = 8x + 4
-14 = 3x + 4
-18 = 3x
x = -6
Answer:
A) 5 (-6) - 14 = 8 (-6) + 4
- 30 - 14 = - 48 + 4
- 44 = - 44
Step-by-step explanation:
La respuesta correcta es la A, ya que x = - 6

Which inequality is represented by this graph? 0 - 345> x O 0 -34.5 0 -355 cx
Answer:
Step-by-step explanation:
If x is the white dot on the graph:
From what it looks like, x is right between -35 and -34 x (which is -35.5).
If that is the case then none of the answers are correct since -35.5 is equal or less than x. (the sign looks like this: "[tex]\leq[/tex]" )
But if you have to choose one of the answers then number 4 (-35.5 < x) would be closest.
Amy and three of her friends went to lunch. The total bill was $54.00. If they wanted to leave a 20% tip how
much more is added tot he bill?
If the girls split the bill evenly, how much does Amy pay?
Answer:
$16.20
Step-by-step explanation:
Bill: $54.00
Tip: 20%
People: 4
To figure out 10% of the bill, you need to move the decimal point over to the left one place: $5.40
10%: $5.40
5.40 times 2 = $10.80
54.00 + 10.80 = 64.80
Grand Total= $64.80
Since there are 4 people, we need to divide by 4:
64.80 divided by 4 = $16.20
