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''.

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''.

Answer:

7 x (y+1/3)

because you take the sum in a parentheses to follow PEDMAS and then multiply the sum by 7

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The algebraic expression of 7 times the sum of y and 1/3 is

7/3 (3y + 1).

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

7 times the sum of y and 1/3

This can be written as,

= 7 (y + 1/3)

=7 (3y + 1) / 3

= 7/3 (3y + 1)

Thus,

The algebraic expression of 7 times the sum of y and 1/3 is

7/3 (3y + 1).

Step-by-step explanation:

The result is: 0.25 and 25% is 2/8 as a decimal and percent.

Here, we have,

given that,

the fraction is:  2/8

now, we have to write as a decimal and percent.

so, we get,

2/8

[ dividing both numerator and denominator by 2 ]

= 1/4

= 0.25

so, we get, 0.25 is a decimal.

now, we have,

0.25 = 25/100 = 25%

so, we have, 25/100 or 25% is the percentage for 2/8.

September = 2.8

Step-by-step explanation:

Given

[tex]Total = 6.2\ in[/tex]

Represent August with A and September with S.

So,

[tex]A =S + 0.6[/tex]

Required

Amount of rainfall in each month.

This is calculated using:

[tex]Total = August + September[/tex]

[tex]6.2= A + S[/tex]

Recall that: A = S + 0.6. Substitute

[tex]6.2= S + 0.6 + S[/tex]

[tex]6.2= 2S + 0.6[/tex]

Collect Like Terms

[tex]2S = 6.2 - 0.6[/tex]

[tex]2S =5.6[/tex]

Solve for S
