Answer:

(I assume you have to do this on some kind of online graphing program.)

Step-by-step explanation:

Plot a point at (0, -3) because that is the y-intercept. Plot the second point at (3, 1). Once you hit “done” your graph should look similar to the one I attached a picture of. *rotatre the picture so the grey is on the bottom*

If the value of x=4, y=3 and z= -2 find the value of 2x+3z​
Oksana_A [137]

Answer:

<h2><em><u>2</u></em></h2>

Step-by-step explanation:

<em><u>To</u></em><em><u> </u></em><em><u>find</u></em><em><u> </u></em><em><u>value</u></em><em><u>:</u></em>

2x + 3z

<em><u>Given</u></em><em><u> </u></em><em><u>values</u></em><em><u>:</u></em>

x = 4, y = 3 and z = -2

<em><u>Solution</u></em><em><u>:</u></em>

2x + 3z

<em>(</em><em>Putting</em><em> </em><em>the</em><em> </em><em>values</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>4</em><em> </em><em>and</em><em> </em><em>z</em><em> </em><em>=</em><em> </em><em>-2</em><em>)</em>

= 2(4) + 3(-2)

= 8 - 6

= <em><u>2 (Ans)</u></em>

Select the correct answer. A circle is described by the equation x2 + y2 + 14x + 2y + 14 = 0. What are the coordinates for the c
son4ous [18]

Answer:

The correct answer is D.

Step-by-step explanation:

Given:

General equation of second degree

x² + y² + 14 x + 2 y + 14 = 0

We must transform given equation to the canonical form from which we will read requested data.

The canonical form of the circle equation is:

(x - p)² + (y - q)² = r²  

Where p and q are the coordinates of the center of the circle and r are radius.    (p,q) = (x,y)

x² + 2 · x ·7 + 7² - 7² + y² + 2 · y · 1 + 1 - 1 + 14 = (x+7)² + (y+1) - 49 - 1 + 14 = 0

(x + 7)² + (y + 1)² = 36

We see that p = - 7 , q = - 1 and  r = 6

God with you!!!

What is 2(x -3) = 7 (x+24)
amm1812

Answer:

x = -34.8

Step-by-step explanation:

<h2><u>solve the equation</u></h2>

2(x-3)

= 2x - 6

7(x + 24 )

= 7x + 168

put the equation together

2x - 6 = 7x + 168

now make x subject of formula:

2x - 7x = 168 +6

-5x = 174

x = 174/ -5

<h3><u>x = -34.8 </u></h3>

A rectangle has a length 10 more than its width. If the width is increased by 8 and the length by 4, the resulting rectangle has
labwork [276]

The equation to model the above scenario is x^{2} +22x - 23 = 0

The perimeter of the expanded rectangle is 48 units

<h3>What is a rectangle?</h3>

A rectangle is a quadrilateral with its 4 angles 90°

Analysis:

First rectangle:

length = 10 + x

width = x

Second rectangle:

length = x + 14

width = x + 8

Area of expanded rectangle = 135 square unit

(x+8)(x+14) = 135

x^{2} + 8x + 14x + 112 = 135

x^{2} + 8x + 14x -23 = 0

x^{2} + 22x -23 = 0

x^{2} + 23x - x - 23 = 0

(x-1)(x+23) = 0

Therefore x = 1

Expanded length = 1+14 = 15

Expanded width = 1+8 = 9

Perimeter = 2(9+15) = 48 units
