Graph the solution set for this inequality: 4x - 2y > 8

mr Goodwill [35]

Answer:

x-intercept: 2 y-intercept= -4

Step-by-step explanation:

First, change the given equation 4x-2y>8 to slope-intercept form, which is y=mx+b. We do this by solving for y.

4x-2y>8. Subtract 4x from each side

-2y> -4x+8. Divide by -2. Don't forget to switch the sign!

y< 2x-4 is our equation in slope-intercept form.

Now, we can graph it. We know the slope (m)= 2 and the y-intercept= -4. Start at -4 and move up two, over one, making points until you can form a line. We can see from the graph that when x=0, (0, -4) y= -4. When y=0, (2, 0), x=2. These are our intercepts of the graph!

Hope this helps!

I don't understand help!!! The subtrahend is 18 and the minuend is 48.

butalik [34]

The subtrahend is 18 and the minuend is 48 which means 18-48=-30 which -30 is called the difference

Derive the equation of a parabola with a focus at (-7,5) and a directrix of y = -11

vivado [14]

Answer:

The equation of the parabola is (x + 7)² = 32(y + 3)

Step-by-step explanation:

* Lets revise the equation of the parabola in standard form

- The standard form is (x - h)² = 4p(y - k)

- The focus is (h , k + p)

- The directrix is y = k - p

* Lets solve the problem

- The parabola has focus at (-7 , 5) and a directrix of y = -11

∵ The focus is (h , k + p)

∵ The focus at (-7 , 5)

∴ h = -7

∴ k + p = 5 ⇒ (1)

∵ The directrix is y = k - p

∵ The directrix of y = -11

∴ k - p = -11 ⇒ (2)

- Add equation (1) and (2) to find k and p

∴ 2k = -6

- Divide both sides by 2

∴ k = -3

- substitute the value of k in equation (1)

∴ -3 + p = 5

- Add 3 to both sides

∴ p = 8

∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)

∴ (x - -7)² = 4(8)(y - -3)

# Remember ⇒ (-)(-) = (+)

∴ (x + 7)² = 32(y + 3)

* The equation of the parabola is (x + 7)² = 32(y + 3)

Which table shows a function that is decreasing only over the interval

joja [24]

Answer:

Table 4th is showing the function that is decreasing only over the interval

Step-by-step explanation:

We have been given four tables below:

To determine the function that is decreasing only in the given interval

$(-1,\infty)$

We will check the values after -1 in all four tables

The table in which values is only decreasing after -1 will be the table which shows a function is decreasing only.

In table 1 the value of x is increasing

In table 2 and 3 the value is increasing and then decreasing but we will consider only decreasing case

Therefore, Table 4th is correct.
