A graphing calculator can be helpful for these.

A) Since neither inequality includes the "or equal to" case, the boundary line for the solution set is a dashed line. For the first inequality, the shading is above the line; for the second, the shading is below the line. The solution set is points to the right of perpendicular lines with slope -2 and +1/2 through point (2, -1).

B) The point -2, 3 satisfies, neither inequality.
.. 3 > -2(-2) +3 . . . FALSE
.. 3 < 1/2(-2) -2 . . .FALSE

Find the point on the parabola y^2 = 8x at which the ordinate is double the abscissa.

aliya0001 [1]

Answer:

Step-by-step explanation:

Let's make a complex of functions

y^2 = 8x

y = 2x

Now let's solve it

(2x)^2 = 8x

4x^2 - 8x = 0

4x(x - 2) = 0

x = 0, 2

y = 0, 4

So the answer is (2, 4)

A lawyer drives from her home, located 3 miles east and 5 miles north of the town courthouse, to her office, located 6 miles wes

This is more of a physics question. Basically you have to separate all the given values into x- and y- coordinates. You are given the home (3 miles East)(5 miles up), so the 3 miles would be on the x axis and the 6 miles on the 6 axis

Given that, you can determine the total displacement of the house from the town using Pythagorean’s theorem. You then do the same with the office and then add your 2 resultant answers together.

The home will be square root 34 miles away from the town, and the office will be square root 85 miles. Adding these together, the answer would be

15,05 miles
Meaning that the lawyers home is 15,05 miles from her office (home to office would be in a south western direction)
