Graphs are used to show the relationship between two variables. In the given graph, as the value of x increases, the value of y decreases.

Given that:

[tex]y = \frac{10}{x}[/tex]

The above function is an inverse function.

This means that:

As the value of x increases, the value of y decreases

Take for instance:

[tex]x= 1[/tex]

[tex]y = \frac{10}{1} = 10[/tex]

Now, [tex]x = 2[/tex]

[tex]y = \frac{10}{2} = 5[/tex]

Notice that:

As x increases from 1 to 2, the corresponding values of y decreases from 10 to 5

Hence, (b) is correct

Answer:

B... all real numbers :)

Answer:

its b: the cost per pint of 3 pints of blueberries if the total cost was 6$

Step-by-step explanation:

5x−y=12 Subtract 5x from both sides of the equation.

− y = 12 − 5 x Divide each term in

− y = 12 − 5 x by - 1 and simplify

y = - 12 + 5 x

i don't know if thats what your answer was but there you go

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

Explanation:

The picture is shown below of what's going on.

The location of point C isn't really important. What is important is the idea that if BC = 3x-8, then AB is also this length as well. The midpoint B cuts segment AC into two equal pieces AB and BC. So that's why AB = BC.

Let's find the distance from A to B

We'll use the aptly named distance formula to get this done (the pythagorean theorem is an alternative route you can take)

[tex]A = (x_1,y_1) = (8,0)\\\\B = (x_2,y_2) = (0,6)\\\\d = \text{distance from A to B} = \text{length of segment AB}\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(8-0)^2 + (0-6)^2}\\\\d = \sqrt{(8)^2 + (-6)^2}\\\\d = \sqrt{64 + 36}\\\\d = \sqrt{100}\\\\d = 10\\\\[/tex]

Therefore, segment AB is 10 units long. Segment BC is also 10 units long.

From here, we can say this:

BC = 3x-8

3x-8 = BC

3x-8 = 10

3x = 10+8

3x = 18

x = 18/3

x = 6 which is the final answer

Throughout this whole process, we never needed to know the location of point C. However, if you're curious about how to find it, then you basically would apply the midpoint formula in reverse.

The length of a football field should be measured in yards

Hi! I'm happy to help!

We know that a football field is separated into 100 (numbers marked on the field.) A football field is also 100 yards, so it would be reasonable to measure it in yards.

Answer:

$1,320

Step-by-step explanation:

~Multiply to find how much money he made that week

55 * 30 = $1,650

~Multiply by 20% then subtract

1,650 * 0.2 = 330

1.650 - 330 = 1,320

Best of Luck!

Answer:

$1320

Step-by-step explanation:

Without taxes and SSI, T'challa would make 55x30 = $1650.

20 % of 1650 is equivalent to 1/5 x 1650.

1/5 x 1650 = 1650/5 = 330

Therefore he makes 1650 - 330 = $1320

Answer:

Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values.

Step-by-step explanation:

Answer:

y = 23x + 95

Step-by-step explanation:

y = mx + b, where m is the slope and b is the y-intercept

The equation of line with a slope of m = 23

y = 23m + b

Since the point (-4,3) is on the line, it will satisfy the equation.

3 = 23(-4) + b

b = 3 - 23(-4)

b = 95

y = 23x + 95

Answer: Choice B

Shelly has 7/8 cup of lemonade. She pours 1/4 cup of lemonade in each glass. How many glasses can Shelly fill?

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

Explanation:

We can think of a similar problem involving [tex]8 \div 4[/tex] which could answer the question "if she has 8 cups and pours 4 cups per glass, then how many glasses can she fill?" (that answer being 2 glasses).

Then we replace the 8 with 7/8, and we also replace the 4 with 1/4. It's the same idea but now things have gotten a bit more complicated since we're dividing two fractions.

Answer:

General equation of a line:

[tex]y = mx + b[/tex]

then express in that form:

[tex] \frac{x}{2} - y + 6 = 0 \\ \\ - y = - \frac{x}{2} - 6 \\ \\ { \boxed{ \boxed{y = \frac{1}{2} x + 6}}}[/tex]

What grade level is this?

Have a nice day! :-)

Explanation:

For now, let's ignore the blue curve.

If we kept the red curve completely fixed in place, and only moved the xy axis, then we can move the xy axis 5 units to the right to give the illusion the red curve is moving (even though it's fixed in place).

Moving the xy axis 5 units to the right means each x input is 5 units larger. So x jumps up to x+5

In other words, going from f(x) to f(x+5) will shift the f(x) curve 5 units to the left. So that's why we go from x^2 to (x+5)^2 which is what choice D shows.
