F(x) = -0.5x2, if f(x) = -112.5, what is the value of 'x'?<br> ?
sleet_krkn [62]

Answer:

x = ± 15

Step-by-step explanation:

Given f(x) = - 0.5x² and f(x) = - 112.5 , then equate right sides

- 0.5x² = - 112.5 ( divide both sides by - 0.5 )

x² = 225 ( take square root of both sides )

x = ± \sqrt{225} = ± 15

Write the point-slope form of the equation of the line that passes through the points (6, 6) and (-6, 1). Include your work in y
Sati [7]

The slope of the lines passing through given points is  \frac{5}{12}.

Step-by-step explanation:

Given,

The given two points are (6,6) and (-6,1).

To find the slope of the line passing through the points.

Formula

The slope of the line passing through (x_{1} ,y_{1}) and (x_{2} ,y_{2})  is \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Now,

Putting, x_{1}=6, y_{1}=6, x_{2}=-6, y_{2}= 1 we get,

Slope = \frac{1-6}{-6-6} = \frac{-5}{-12} = \frac{5}{12}

Hence,

The slope of the lines passing through given points is  \frac{5}{12}.

6 + 2(x-5) = -40 - 5(x-3)<br><br> Help
bagirrra123 [75]
6 + 2(x - 5) = -40 - 5(x - 3)
6 + 2x - 10 = -40 - 5x + 15
-4 + 2x = -25 - 5x
2x = -21 - 5x
7x = -21
x = -3
