What’s the value of y?
What’s the value of x?

Answer: Choice A.  (8, 4)

==========================================================

Explanation:

Because x = 2y, we can replace every copy of x with 2y

Let's do so in the second equation

3x - 4y = 8

3(x) - 4y = 8

3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y

6y - 4y = 8

2y = 8

y = 8/2 ..... divide both sides by 2

y = 4

Use this y value to find x

x = 2y

x = 2*4

x = 8

So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

Hey!

0.309<0.32<0.35<0.4

hope this helps you

The numbers in order of size start with the smallest can be done as 0.309 < 0.32 < 0.35 < 0.40.

The decimal numeral system is the most widely used system for representing both integer and non-integer values. It is the Hindu-Arabic numeral system's expansion to non-integer numbers. Decimal notation is the method of representing numbers in the decimal system.

The given number can be arranged from smallest to largest can be arranged as shown below. Therefore, we can write,

0.309 < 0.32 < 0.35 < 0.40

Hence, the numbers in order of size start with the smallest can be done as 0.309 < 0.32 < 0.35 < 0.40.

Domain implies that we list the possible x values.

There are 4 quadrants and the x values in each quadrant are:

First quadrant: x is positive

Second quadrant: x is negative

Third quadrant: x is negative

Fourth quadrant: x is positive

From the above lists, we can see that x is negative in the second and the third quadrants.

Answer:

g(x) is horizontally stretched by a factor of 1/5

Step-by-step explanation:

Given

[tex]f(x) = x^2[/tex]

[tex]g(x) = (\frac{x}{5})^2[/tex]

Require

Determine the relationship between f(x) and g(x)

[tex]f(x) = x^2[/tex]

[tex]g(x) = (\frac{x}{5})^2[/tex]

Express g(x) in terms of f(x)

[tex]g(x)=f(\frac{x}{5})[/tex]

This can further be simplified as:

[tex]g(x)=f(\frac{1}{5}x)[/tex]

When a function is represented as:

[tex]g(x) = f(cx)[/tex]

Where c < 1,

Then the type of translation is a horizontal stretch (stretch in the x direction)

By comparison: [tex]g(x) = f(cx)[/tex] and [tex]g(x)=f(\frac{1}{5}x)[/tex]

[tex]c = \frac{1}{5}[/tex]

This means that: g(x) is horizontally stretched by a factor of 1/5

a = 72° b = 88°

Step-by-step explanation:

We know in the cyclic quadrilateral opposite angles are supplementary so

a + 108° = 180° { being opposite angles of cyclic quadrilateral }

a = 180° - 108°

a = 72°

b + 92° = 180° { being opposite angles of cyclic quadrilateral }

b = 180° - 92°

b = 88°

Answer:

B

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The line passes through the point (2, -1/2) and has a slope of 3.

We can use the point-slope form, given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where (x₁, y₁) is a point, and m is the slope.

Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:

[tex]\displaystyle y-\Big(-\frac{1}{2}\Big)=3(x-(2))[/tex]

Simplify:

[tex]\displaystyle y+\frac{1}{2}=3(x-2)[/tex]

Therefore, our answer is C.
