Answer:

Yes

Step-by-step explanation:

$( {12.5)}^{2} = 156.25...(1) \\ ( {7.5)}^{2} + ( {10)}^{2} \\ = 56.25 + 100 = 156.25...(2) \\ from \: equations \: (1) \: and \: (2) \\ ( {12.5)}^{2} =( {7.5)}^{2} + ( {10)}^{2} \\ \therefore \: given \: side \: lengths \: form \: right \: \\triangle \\ (by \: converse \: of \: pythagorean \: \\ theorem)$

Describe a real world situation between the area of a rectangle and its width, as the width varies and the length stays the same

raketka [301]

Area of rectangle = length x width If length is constant, say c and width is variable, say x Area of rectangle = y = cx This means Area will vary linearly with width and will represent a line with slope... hope I helped

What is the answer???

vagabundo [1.1K]

Answer:

3. $\displaystyle x-intercept: [-4\frac{1}{2}, 0] \\ y-intercept: [0, -9] \\ Slope-Intercept\:Form: y = -2x - 9$

2. $\displaystyle x-intercept: [5, 0] \\ y-intercept: [0, 1] \\ Slope-Intercept\:Form: y = -\frac{1}{5}x + 1$

1. $\displaystyle x-intercept: [4, 0] \\ y-intercept: [0, -3] \\ Slope-Intercept\:Form: y = \frac{3}{4}x - 3$

Step-by-step explanation:

−2x - y = 9

x-intercept → Plug in 0 for <em>y</em><em> </em>to get −4½ for <em>x</em>

y-intercept → Plug in 0 for <em>x</em><em> </em>to get −9 for <em>y</em>

−2x - y = 9

+ 2x + 2x

_________

$\displaystyle \frac{-y}{-1} = \frac{2x + 9}{-1}$

$\displaystyle y = -2x - 9 →$ <em>Slope-Intercept</em><em> </em><em>Form</em>

_______________________________________________

x + 5y = 5

x-intercept → Plug in 0 for y to get 5 for x

y-intercept → Plug in 0 for x to get 1 for y

x + 5y = 5

- x - x

_________

$\displaystyle \frac{5y}{5} = \frac{-x + 5}{5}$

$\displaystyle y = -\frac{1}{5}x + 1 →$ <em>Slope-Intercept Form</em>

_______________________________________________

3x - 4y = 12

x-intercept → Plug in 0 for y to get 4 for x

y-intercept → Plug in 0 for x to get −3 for y

3x - 4y = 12

- 3x - 3x

_________

$\displaystyle \frac{-4y}{-4} = \frac{-3x + 12}{-4}$

$\displaystyle y = \frac{3}{4}x - 3 →$ <em>Slope-Intercept Form</em>
