$\huge\boxed{\text{This equation has no solution.}}$

Distribute the $-4$ to the $(2-x)$ . $7-3x=x-8-4x$

Rearrange the terms. $-3x+7=-4x+x-8$

Combine the like terms. $-3x+7=-3x-8$

Add $3x$ on both sides. $7=-8$

This statement is false, so the equation has $\boxed{\text{no solution}}$ .

The function

Ghella [55]

Functions can be represented by equations and graphs

There are 2 million users online at 9 am
The domain is [0,23], while the range is [2, $\infty$ )

<h3>The number of users at 9am</h3>

The function is given as:

$g(x) = \frac 14\sqrt[3]{x - 3} + 2$

At 9am, x = 9.

So, we have:

$g(x) = \frac 14\sqrt[3]{9 - 3} + 2$

Evaluate the difference

$g(x) = \frac 14\sqrt[3]{6} + 2$

Evaluate the exponent

$g(x) = \frac 14 * 1.8 + 2$

$g(x) = 0.45 + 2$

Evaluate the sum

$g(x) = 2.45$

Approximate

$g(x) = 2$

Hence, there are 2 million users online at 9 am

<h3>The function transformation</h3>

We have:

$g(x) = \frac 14\sqrt[3]{x - 3} + 2$

The parent function is:

$f(x) = \sqrt[3]{x}$

So, the transformations applied to the parent function are:

Vertical compression by a scale factor of 4
Horizontal shift to the right by 3 units
Vertical shift up by 2 units

<h3>The domain and the range</h3>

The domain is the possible input values, and the range are the possible output values.

There are 24 hours in a day.

So, the domain is:

Domain = [0,23]

While the range is [2, $\infty$ )

What graph represents −3x+1≤10

nalin [4]

The solution of the inequality is x ≥ -3 and the graph is shown below

<h3>Graph of inequalities </h3>

From the question, we are to determine the graph that represents the given inequality

The given inequality is

−3x + 1 ≤ 10

First, we will solve the inequality

−3x + 1 ≤ 10

Subtract 1 from both sides

−3x +1 -1 ≤ 10 - 1

−3x ≤ 9

Divide both sides by -3 and<u> flip the sign</u>

x ≥ -3

The graph of the inequality is shown below

<h2>Finding the y-intercept given the Graph of the Line</h2>

Answer:

The $y$ -intercept is $\boxed{3}$

Step-by-step explanation:

The $y$ -intercept of line is just the point where the $y$ -axis and the line. From the given line, we can see that the $y$ -axis and the line that models the temperature on a certain winter day since sunrise $(0,3)$ . Also, the question just asked us for the $y$ -coordinate of the $y$ -intercept so $3$
