LuckyWell [14K]

Answer:

<h2>D. 3</h2>

Step-by-step explanation:

$\bold{METHOD\ 1}$

$\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{x-intercept:}\ (x,\ 0).\\\\\text{Susbtitute the coordinates of the points to the formula of a slope}\\\\(-3,\ -4),\ (6,\ 2),\ (x,\ 0):\\\\m=\dfrac{2-(-4)}{6-(-3)}=\dfrac{2+4}{6+3}=\dfrac{6}{9}=\dfrac{6:3}{9:3}=\dfrac{2}{3}\\\\m=\dfrac{0-2}{x-6}=\dfrac{-2}{x-6}\\\\\text{Therefore we have the equation:}\\\\\dfrac{-2}{x-6}=\dfrac{2}{3}\qquad\text{cross multiply}\\\\2(x-6)=(-2)(3)\\\\2(x-6)=-6\qquad\text{divide both sides by 2}\\\\x-6=-3\qquad\text{add 6 to both sides}\\\\x=3$

$\bold{METHOD\ 2}\\\\\text{Look at the picture.}$

If 3/4 is the dividend and -2/5 is the divisor then what is the quotient ?

Alexxx [7]

Answer:

$\dfrac{-15}{8}$

Step-by-step explanation:

<h3>Fraction division:</h3>

$\sf \dfrac{3}{4} \ \div \dfrac{-2}{5}$

Use KCF method.

Keep the first fraction.
Change division to multiplication
Flip the second fraction.

$\sf \dfrac{3}{4} \ \div \dfrac{-2}{5}=\dfrac{3}{4}*\dfrac{-5}{2}$

$\sf = \dfrac{3*(-5)}{4*2}\\\\ =\dfrac{-15}{8}$
