Express the area of the rectangle in term of x

aalyn [17]

Answer:

Area = $12-\frac{4}{35}x$

Step-by-step explanation:

Length of the given rectangle 'l' = (15 - $\frac{1}{7}x$ )

Width of the given rectangle 'w' = $\frac{4}{5}$

Area of the rectangle = lw

= $\frac{4}{5}(15-\frac{1}{7}x)$

= $\frac{4\times 15}{5}-\frac{4}{5}\times \frac{1}{7}x$

= $12-\frac{4}{35}x$

Therefore, expression that defines the area of the given rectangle will be,

Area = $12-\frac{4}{35}x$

Which expression is equivalent to (4p^-4 q)^-2/ 10pq^-3?

Anit [1.1K]

Answer:

$\dfrac{p^{7} q}{160}$

Step-by-step explanation:

$\dfrac{(4p^-4 q)^-2}{10pq^-3} =$

$= \dfrac{4^{-2}p^{-4\times (-2)} q^{-2}}{10pq^-3}$

$= \dfrac{4^{-2}}{10}p^{8-1} q^{-2-(-3)}$

$= \dfrac{1}{4^2 \times 10}p^{7} q^{-2 + 3}$

$= \dfrac{1}{160}p^{7} q$

$= \dfrac{p^{7} q}{160}$

Points (3,1) and (1,4) lie on line k. What is the slope of the line that is perpendicular to k?

denis-greek [22]

First we need to find the slope of line k. Using the slope formula, we fill in accordingly: $m= \frac{4-1}{1-3}$ . The slope is -3/2. The slope of a line that is perpendicular to line k will have the opposite sign (so, positive) and will be the reciprocal of the line k's slope (so, 2/3). You could also say, more "mathematically legal", that the product of the slopes of perpendicular lines is -1, but it's easier to just say that they are opposite reciprocals. The slope you're looking for is 2/3. Choice 3 above.
