Wittaler [7]

Answer:

The coordinates of the image of vertex P after reflection is  (-7, 4)

Step-by-step explanation:

Given that we are to reflect the point P across the x-axis, we have;

Reflection of a point across the x-axis gives;

When a point is reflected across the x axis, the y-coordinate changes to the opposite sign while the x-coordinate remains unchanged  such that (x, y) becomes (x, -y)

Therefore, given that the point P = (-7, -4), we have;

Coordinates of point P before reflection Reflection = (-7, -4), coordinates of point P after reflection Reflection P' = (-7, 4).

Which of the following is the solution set to the inequality −25x+14>20?
Bezzdna [24]

Answer:

Option C. x < -15

Step-by-step explanation:

<u><em>The correct inequality is</em></u>

-\frac{2}{5}x+14 >20

Solve for x

subtract 14 both sides

-\frac{2}{5}x+14-14 >20-14

-\frac{2}{5}x >6

Multiply by -1 both sides

\frac{2}{5}x < -6

Multiply by 5/2 both sides

x < -6(\frac{5}{2})

x < -15
