Answer: he spends 2.5 hours in the weight room each week.

Step-by-step explanation: 2.5 multiplied by 2 (which is the twice amount of time spent working out in the pool) is 5.

So the answer is 2.5

Answer: y=0.60x+36.94

To find the equation we just set y equal to the 0.60 cents times x miles plus the 36.94 base fee. Any questions just ask. Cheers

Write an equation of the line that passes through the given points: (9/2,1), (-7/2,7) please show step by step how to do this. T

Viktor [21]

Explanation:

The easiest way to do this is to make use of the 2-point form of the equation for a line. For points (x₁, y₁) and (x₂, y₂), the equation is ...

$y=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)+y_1$

Filling in your given points, the equation becomes ...

$y=\dfrac{7-1}{\frac{-7}{2}-\frac{9}{2}}(x-\frac{9}{2})+1$

After you fill in the values, it is a matter of simplifying the resulting equation.

$y=\dfrac{6}{\frac{-16}{2}}(x-\frac{9}{2})+1=\dfrac{-12}{16}(x-\frac{9}{2})+1=-\dfrac{3}{4}x+\left(\dfrac{-3}{4}\cdot\dfrac{-9}{2}\right)+1\\\\y=-\dfrac{3}{4}x+\dfrac{27+8}{8}\\\\y=-\dfrac{3}{4}x+\dfrac{35}{8}$

what is the slope of a line that is perpendicular to the line that contains points (5,4) and (-7,9). explain please

Luba_88 [7]

Answer:

$\frac{12}{5}$

Step-by-step explanation:

First find the slope of the line containing points (5,4) and (-7,9). To find the slope use the formula $\frac{y_{2} -y_{1}}{x_{2}-x_{1}}$ . Putting those values in, you have

$\frac{9-4}{-7-5}$

Simplify

$\frac{5}{-12}$

$-\frac{5}{12}$

Then, to find the slope of the line perpendicular to that, find the negative reciprocal.

$\frac{12}{5}$
