Answer:

D, R: {11, -4, -29}

Step-by-step explanation:

According to the given set of domains, the corresponding range is found by substituting the x values into the equation and solving for y.

i.e {-2} -> 5x + y = 1, -10 + y = 1, y = 11

{1} -> 5x + y = 1, 5 + y = 1, y = -4

{6} -> 5x + y = 1, 30 + y = 1, y = -29

Answer:

Option C. Yes; y=2x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem

For x=0, y=0

That means ----> the line passes through the origin

Find the value of k

For x=2, y=4

$k=\frac{y}{x}$ ----> $k=\frac{4}{2}=2$

For x=4, y=8

$k=\frac{y}{x}$ ----> $k=\frac{8}{4}=2$

The values of k are equal

therefore

The table represent a direct variation

The equation is equal to

$y=2x$

What are Conic Sections and how are they formed?

sukhopar [10]

Answer:

In mathematics, a conic section is a curve obtained as the intersection of the surface of a cone with a plane. The three types of conic section are the hyperbola, the parabola, and the ellipse; the circle is a special case of the ellipse, though historically it was sometimes called a fourth type.

Conic sections are formed on a plane when that plane slices through the edge of one or both of a pair of right circular cones stacked tip to tip.

PolarNik [594]

Answer:

The answer is 4a

Step-by-step explanation:

1) Simplify 4a² + 12a² to 16a².

$\sqrt{ {16a}^{2} }$

2) Use this rule:

$\sqrt{ab} = \sqrt{a} \sqrt{b}$

$\sqrt{16} \sqrt{ {a}^{2} }$

3) Since 4 × 4 is 16, the square root of 16 is 4.

$4 \sqrt{ {a}^{2} }$

4) Simplify.

$4a$

Therefor, the answer is 4a.

Which number is equivalent to 0.000 000 1 : 10^7 or 10^-7 and why

kondaur [170]

It would be 10^-7.

When you have a negative number in scientific notation, you count a whole zero and start counting behind the decimal point because a negative number is less than 0. So, it cannot have a value over 0. Though if it was after the decimal, it would be the positive answer because a positive number is higher than 0.

An example would be:
10^-3=0.001
10^3=1000
