\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \parallel\ k\iff m_1=m_2\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\----------------------\\\\\text{The slope-intercept form:}\ y=mx+b.\\\\\text{We have}\ y=\dfrac{2}{3}x+3\to m_1=\dfrac{2}{3}.\ \text{Therefore}\\\\m_2=-\dfrac{1}{\frac{2}{3}}=-\dfrac{3}{2}\\\\\text{We have the equation}\ y=-\dfrac{3}{2}x+b.

\text{Put the coordinates of the given point (6, -8) to the equation:}\\\\-8=-\dfrac{3}{2}(6)+b\\\\-8=-(3)(3)+b\\\\-8=-9+b\qquad\text{add 9 to both sides}\\\\1=b\to b=1\\\\Answer:\ \boxed{y=-\dfrac{3}{2}x+1}

Answer:

10 > v (if you don't trust me, check it yourself. Subsitute v for 10 in the first equation.

Step-by-step explanation:

1) 7 > v - 3

2) add 3 to both sides

3) so 7 plus 3 equals 10

So you basically do this

7 > v - 3 (ad 3 to both sides)

You get 10 > v (which is as simplified as possible)

Hope this helps! :)

Kryger [21]

Answer:

OPTION B

Step-by-step explanation:

<h2>3a - 5</h2>

3 and 'a' are multiplied and 5 is subtracted from the result.

OPTION B says 5 less than 3 times a number would fit perfectly.

Other options talk about adding or taking ratios and clearly do not fit the case.

Hence, the right answer is Option B.
