Select the correct answer.

Answer:

$\frac{5}{4} x - 2 = \frac{3}{2} x-4$

Step-by-step explanation:

$\frac{5}{2} x +\frac{7}{2} =\frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14-\frac{7}{2} \\\frac{10-3}{4} x =\frac{28-7}{2} \\\frac{7}{4} x =\frac{21}{2} \\x = \frac{21}{2} * \frac{4}{7} = 6 \\$

$\frac{5}{4} x -9 = \frac{3}{2} x-12 \\\frac{5}{4} x - \frac{3}{2} x= -12 + 9 \\\frac{5-6}{4} x = -3 \\\frac{-1}{4} x = -3 \\x = -3 * -4 \\x = 12$

$\frac{5}{4} x-2=\frac{3}{2} x-4 \\\frac{5}{4} x-\frac{3}{2} x=-4+2 \\\frac{5-6}{4}x=-2 \\\frac{-1}{4} x = -2 \\x = -2 * -4 \\x = 8$

$\frac{5}{2} x -7 = \frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14+7 \\\frac{10-3}{4} x =21 \\\frac{7}{4} x =21 \\x = 21 * \frac{4}{7} = 12 \\$

You could also replace x for 8 in every equation and see if both sides give the same answer

The vector parametric equation for the line through the points (−1,−4,2) and (−1,0,−3) is:_______

ollegr [7]

Answer: $x(t)=-1$

$y(t)=-4+4(t)$

$z(t)=2-5(t)$

Step-by-step explanation:

To find: The vector parametric equations for the line through the points (−1,−4,2) and (−1,0,−3).

Let A (−1,−4,2) and B(−1,0,−3)

First we find direction vectors : $\overrightarrow{AB}=$

Now, the parametric equations of the line:

$x(t)=-1+0(t)$

$y(t)=-4+4(t)$

$z(t)=2-5(t)$

Hence, the vector parametric equations for the line through the points (−1,−4,2) and (−1,0,−3):

$x(t)=-1$

$y(t)=-4+4(t)$

$z(t)=2-5(t)$
