Joe buys a compact disc that costs $29.99. He give the store clerk $50.00.

How much change should he get?

Answer:

[tex]y = -3x[/tex]

Step-by-step explanation:

Given

The attached graph

Required

Determine the graph equation

To do this, we pick any 3 corresponding points of x and y

[tex](x_1,y_1) = (0,0)[/tex]

[tex](x_2,y_2) = (2,-6)[/tex]

[tex](x_3,y_3) = (-4,12)[/tex]

The equation can then be solved using linear interpolation as follows:

[tex]\frac{y-y_3}{x-x_3} = \frac{y_2 - y_1}{x_2-x_1}[/tex]

This gives:

[tex]\frac{y-12}{x-(-4)} = \frac{-6 -0}{2-0}[/tex]

[tex]\frac{y-12}{x+4} = \frac{-6 -0}{2-0}[/tex]

[tex]\frac{y-12}{x+4} = \frac{-6}{2}[/tex]

[tex]\frac{y-12}{x+4} = -3[/tex]

Multiply both sides by x + 4

[tex](x + 4) * \frac{y-12}{x+4} = -3 * (x + 4)[/tex]

[tex]y - 12 = -3 *(x + 4)[/tex]

Open bracket

[tex]y - 12 = -3x -12[/tex]

Add 12 to both sides

[tex]y - 12+12 = -3x -12+12[/tex]

[tex]y = -3x[/tex]

Answer:

28 x 784

Step-by-step explanation:

Now 7 remains without a pair and therefore 7 should be multiplied to 112 to make it a perfect square. Similarly 28 should be multiplied to 784 to make it a perfect cube.

hope it helps, pls mark as brainliest and follow . thnx

Answer:

  slope = 2

Step-by-step explanation:

See the attachment for the markup.

It is usually convenient to choose places where the graph crosses grid intersections. Here, the graph crosses the x- and y-axes at integer values, so those points could be used, for example. We chose points away from the axes so that the rise and run lines could be seen more easily.

The graph has a rise/run of ...

  slope = rise/run = 2/1 = 2

The slope of the line is 2.

This is the answer to your question

Answer:

5/20 and 8/20

Step-by-step explanation:

The LCM of denominators is 20

Answer:

a) The estimates for the solutions of [tex]4\cdot x^{2}-4\cdot x -1 = 0[/tex] are [tex]x_{1}\approx -0.25[/tex] and [tex]x_{2} \approx 1.25[/tex].

b) The estimates for the solutions of [tex]4\cdot x^{2}-4\cdot x -1 = 2[/tex] are [tex]x_{1}\approx -0.5[/tex] and [tex]x_{2} \approx 1.5[/tex]

Step-by-step explanation:

From image we get a graphical representation of the second-order polynomial [tex]y = 4\cdot x^{2}-4\cdot x -1[/tex], where [tex]x[/tex] is related to the horizontal axis of the Cartesian plane, whereas [tex]y[/tex] is related to the vertical axis of this plane. Now we proceed to estimate the solutions for each case:

a) [tex]4\cdot x^{2}-4\cdot x -1 = 0[/tex]

There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

[tex]x_{1}\approx -0.25[/tex], [tex]x_{2} \approx 1.25[/tex]

b) [tex]4\cdot x^{2}-4\cdot x -1 = 2[/tex]

There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

[tex]x_{1}\approx -0.5[/tex], [tex]x_{2} \approx 1.5[/tex]

Answer:

B. 8:45

Step-by-step explanation:

One quarter of an hour is 15 minutes, meaning a quarter till nine is 15 minutes before nine, or 8:45.

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤

[tex]f(x) = - 5 {x}^{2} + 10x + 8[/tex]

[tex]0 = - 5 {x}^{2} + 10x + 8[/tex]

[tex] - 5 {x}^{2} + 10x + 8 = 0[/tex]

[tex]delta = {10}^{2} - 4( - 5)(8)[/tex]

[tex]delta = 100 + 160[/tex]

[tex]delta = 260[/tex]

[tex]x = \frac{ - (10) + \sqrt{delta} }{2 \times ( - 5)} \\ [/tex]

[tex]x = \frac{ - 10 + \sqrt{260} }{ - 10} \\ [/tex]

[tex]x = \frac{ - 10 + 2 \sqrt{65} }{ - 10} \\ [/tex]

[tex]x = \frac{ - 5 + \sqrt{65} }{ - 5} \\ [/tex]

And

[tex]x = \frac{ - 10 - \sqrt{delta} }{ - 10} \\ [/tex]

[tex]x = \frac{ - 10 - 2 \sqrt{65} }{ - 10} \\ [/tex]

[tex]x = \frac{ 5 + \sqrt{65} }{5} \\ [/tex]

______________________________________

Thus list the zeroes of the function is :

[tex]x = \frac{ - 5 + \sqrt{65} }{ - 5} \\ [/tex]

And

[tex]x = \frac{5 + \sqrt{65} }{5} \\ [/tex]

For Literature = 90 pages

For Grammar = 60 pages

Step-by-step explanation:

An English book consists of two sections, literature and grammar, in a ratio of 3:2. How much of each type of content will be needed to make a book of 150 pages?

Literature : Grammar

3 : 2

Total number of Proportion = 3 + 2 = 5

For Literature

= 3/5 × 150 pages

= 90 pages

For Grammar

= 2/5 × 150 pages

= 60 pages

Answer:

$-21

Step-by-step explanation:

Since she is paying $6 for 4 weeks, in total she will pay:

6 x 4 = $24

She has an initial balance of $-45 Because she is in debt

Therefore you just need to add it all up

-45 + 24 = $-21

Answer:

-24
