Help!! Which of the following uses the reciprocal property to rewrite 12/x-3 = 20/x+3?
loris [4]

<em><u>The reciprocal property is:</u></em>

\frac{x - 3}{12} = \frac{x + 3}{20}

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

Given that,

\frac{12}{x - 3} = \frac{20}{x + 3}

<em><u>The reciprocal property is given as:</u></em>

The reciprocal of a fraction is the numerator and denominator switched

\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}

Therefore,

\frac{12}{x - 3} = \frac{20}{x + 3}

By reciprocal property,

Switch the numerator and denominator of right side fraction as well as left side fraction

The we get,

\frac{x - 3}{12} = \frac{x + 3}{20}

Thus option C is correct

Need help all mult choice show some type of work/proof
Brrunno [24]

AD is the diagonal of a 6 by 15 rectangle,

31.

AD^2 = 6^2+15^2=36+225=261 = 9(29)

AD=3 \sqrt{29}

Choice A

32.

d^2 = 2^2+3^2=4+9=13

d=\sqrt{13}

Choice A

33.

7 - 4x = 7y

4x + 7y = -7

The parallel through (2,0) keeps the coefficients on x and y and just changes the constant:

4x + 7y = 4(2)+7(0)= 8

7y = -4x + 8

y = (-4/7) x + 8/7

Choice B

Subtract.<br> (5x4+ 3x3 - 6) - (8x2 – 3x+5)
Savatey [412]

Answer:

5x^4+3x^3-8x^2+3x-11

Step-by-step explanation:

(5x^4+ 3x^3 - 6) - (8x^2 – 3x+5)

Distribute the minus sign

(5x^4+ 3x^3 - 6) - 8x^2 + 3x-5

Combine like terms

5x^4+3x^3-8x^2+3x-11
