3,2 is the answer...hope you can understand

The point which is the solution of the inequality y ≤ 2x - 4 is,

⇒ (3, 2)

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

We have to given that;

The inequality is,

⇒ y ≤ 2x - 4

Now, From the options;

Option 3;

Point = (3, 2)

Put x = 3, y = 2;

⇒ y ≤ 2x - 4

⇒ 2 ≤ 2 × 3 - 4

⇒ 2 ≤ 6 - 4

⇒ 2 ≤ 2

Thus, The point which is the solution of the inequality y ≤ 2x - 4 is,

⇒ (3, 2)

Answer:

The answer is C

I did the quiz on edge

Do you mean [tex]f(x)=-3^{\sqrt x}[/tex], as in the negative of 3 to the power of √x ? Or [tex]f(x)=-\sqrt[3]{x}[/tex], as in the negative cube root of x ?

If you mean [tex]f(x)=-3^{\sqrt x}[/tex], then, going through each option:

• no: the square root component is defined only for x ≥ 0, for which we have √x ≥ 0 and hence f(x) < 0 for all x in the domain. √x is an increasing function, so the powers of 3 get successively larger, so f(x) would be always decreasing;

• no: as mentioned above, the domain would be all non-negative numbers;

• no: at minimum, x = 0 which gives f (0) = -3⁰ = -1, and because f(x) is decreasing over its entire domain, the range would be {y | y ≤ -1};

• no: again, a bit of ambiguity, but assuming you mean to say here [tex]y=3^{\sqrt x}[/tex], yes, f(x) would be a reflection of y across the x-axis;

• and finally, no: [tex]f(3)=-3^{\sqrt3}\approx-6.705[/tex]

so that only the fourth option would be true.

On the other hand, if you mean [tex]f(x)=-\sqrt[3]{x}[/tex], then:

• no: the function is always decreasing;

• yes: the domain is all real numbers;

• yes: the range is {y | -∞ < y < ∞};

• yes: f(x) is a reflection of y=∛x, also about the x-axis; and

• no: f (3) = -∛3 ≈ -1.442

I suspect you mean the second case, since it's a bit simpler to approach.

Answer:

B. 13.2 m

Step-by-step explanation:

Using the Pythagorean theorem, which is a^2 + b^2 = c^2, you can substitute in 9 for a and 16 for c. This puts it at 9^2 + b^2 = 16^2, which equals 81 + b^2 = 256. Subtract 81 from both sides to get b^2 = 175. Take the square root of both sides to get b = sqrt 175. The sqrt of 175 rounded to the nearest tenth is 13.2

Answer:

The value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

Step-by-step explanation:

Given the expression

[tex]13\:-\:0.75y\:+\:8x[/tex]

Given

substituting y = 12 and x = 1/2 in the expresion

[tex]13\:-\:0.75y\:+\:8x=13\:-\:0.75\left(12\right)\:+\:8\left(\frac{1}{2}\right)[/tex]

                            [tex]=13-0.75\cdot \:12+8\cdot \frac{1}{2}[/tex]

                             [tex]=13-9+4[/tex]

                             [tex]=8[/tex]

Therefore, the value of 13 - 0.75y + 8x when we substitute y = 12 and x = 1/2 will be: 8

Answer:

1a. y = $10 + $5x (With $10 as the flat fee, Company A charges $5 an hour, so the equation should be $10, base, plus $5x, the amount charged after you paid the flat fee.)

1b. y = $7x (Every hour $7 translates to $7x as the total. Nothing more, nothing less.)

1c. Substitution (This will allow us to substitute in one of the equations with y, since the question asks for the same amount charged, with the other equation.)

1d. $10 + $5x = $7x

    $7x - $5x = $10

    $2x = $10

    x = [tex]\frac{\$10}{\$2}[/tex]

    x = 5

Therefore, after 5 hours, both companies charge $35 dollars.

1e. To check whether this is correct, let's sub in the amount of hours for both equations.

For Company A:

y = $10 + $5x

y = $10 + $5(5)

y = $35

For Company B:

y = $7x

y = $7(5)

y = $35

Since both are equal to $35, we can definitively say the answer is 5 hours.

Answer:

The answer is "-21.6".

Step-by-step explanation:

In the given question, there is a mistype in the equation so, its correct equation can be defined as follows:

Given:

[tex]\to (-9) (2 \ and \ 2/5) = (-9)(2+ \frac{2}{5})[/tex]

                              [tex]= (-9 \times 2 )+ (-9\times \frac{2}{5})\\\\= (-18 )+ ( -\frac{18}{5})\\\\= -18 -\frac{18}{5}\\\\= \frac{-90-18}{5}\\\\= - \frac{108}{5}\\\\=- 21.6[/tex]

OR

[tex]\to (-9)(2+ \frac{2}{5})= (-9) (\frac{10+2}{5})[/tex]

                       [tex]= (-9) (\frac{12}{5})\\\\= (-9) (2.4)\\\\=-21.6[/tex]

768 numbers

Step-by-step explanation:

Given

[tex]Digits = \{0,1,2,3,4,5,6,7,8,9\}[/tex]

Required

Number of digits between 0 ad 9999 that have one 1 and one 3

There are a total of 4 digits that make up any of the numbers in 0 to 9999 with the given condition

This can be represented as WXYZ

The remaining 8 digits will occupy the last 2 positions in the following ways:

So, the total number of selection is:

[tex]Total = 4 * (4 - 1) * 8 * 8[/tex]

[tex]Total = 4 * 3 * 8 * 8[/tex]

[tex]Total = 768[/tex]
