Answer:

3.4

Step-by-step explanation:

The opposite of a number is the same as the additive inverse of the number.

Two numbers are opposites, or additive inverses, if they add to zero.

For a positive or a negative number, just change its sign to find its opposite. For zero, its additive inverse is zero.

The opposite of -3.4 is 3.4.

Answer: 3.4

<h3>hello!</h3>

The opposite of a positive number is a negative number.

The opposite of a negative number is a positive number.

-3.4 is a negative number, so its opposite is a positive number.

Hence, the answer is 3.4

What is the value of x in the question 5/8=x/52
skad [1K]
X= 32.5

You have to change the denominators (8 and 52) to be the same (52).

52/8=6.5

So 6.5 is your scale factor.

Simply multiply your numerator (5) by 6.5 to get 32.6

The regular price of a dvd is $24?. During a sale, the price of a dvd is marked down 30%. What will the sale price of the dvd?
Tatiana [17]

If a $24 dvd is marked down by 30% then the cost of the dvd would be 70% of the original cost. 100% - 30% = 70%

70% of 24 can be expressed as 0.7 x 24.

The answer is $16.80.

Hope this helps :)

I need help with this problem down below
Misha Larkins [42]

Answer:

y = 4

Step-by-step explanation:

Given:

y = \frac{7x + 1}{3x - 6},

To find the value of y, let's find x by solving 3x = 15.

3x = 15

Divide both sides by 3

x = 15/3

x = 5

Plug in the value of x into y = \frac{7x + 1}{3x - 6}

y = \frac{7(5) + 1}{3(5) - 6}

y = \frac{35 + 1}{15 - 6}

y = \frac{36}{9}

y = 4

The focus of a parabola is (0, -3) and the directrix is y = 3. What is the equation of the parabola?
OleMash [197]

Answer:

The equation of the parabola is y = -12\cdot x^{2}.

Step-by-step explanation:

Since the directrix is of the form y = a, the parabola is vertical. The vertex of the parabola (V(x,y)) is the midpoint between the focus (F(x,y)) and a point of the directrix (P(x,y)), that is to say:

V(x,y) = \frac{1}{2}\cdot F(x,y) + \frac{1}{2}\cdot P(x,y) (1)

If we know that F(x,y) = (0, -3) and P(x,y) = (0, 3), then the coordinates of the vertex of the parabola:

V(x,y) = \frac{1}{2}\cdot (0, -3) + \frac{1}{2}\cdot (0, 3)

V(x,y) = (0, 0)

The vertex factor (p) is the distance of the focus with respect to the vertex:

p = \sqrt{[F(x,y)-V(x,y)]\,\bullet \,[F(x,y)-V(x,y)]} (2)

If we know that F(x,y) = (0, -3) and V(x,y) = (0, 0), then the vertex factor is:

p = \sqrt{0^{2}+(-3)^{2}}

p = -3

The equation of the parabola in the vertex form is described below:

y - k = 4\cdot p \cdot (x-h)^{2} (3)

Where:

x - Independent variable.

y - Dependent variable.

h, k - Coordinates of the vertex.

If we know that (h,k) = (0, 0) and p = -3, then the equation of the parabola is y = -12\cdot x^{2}.
