A point is reflected across the x-axis. The new point is located at (4.75, -2.25) Where was the original point located.
sergejj [24]

Answer:

(4.75, 2.25)

Step-by-step explanation:

Given the coordinate (x,y). If this coordinate is reflected over the x axis, the resulting coordinate will be (x, -y)

Note that the y coordinate was negated.

Let the original point needed be (x, y)

If the new point is located at (4.75, -2.25)

Since the y coordinate was negated, then;

-y = -2.25

y = 2.25

x = 4,75 (x coordinate remains the same)

Hence the original point is (4.75, 2.25)

What is the value of h?<br> h = 20<br> h=35<br> h = 70<br> (2h)<br> (2h)
postnew [5]

Answer:

-7/2 or -3.5

Step-by-step explanation:

h = 20 = h = 35  = h = 70  (2h)  (2h)

19h = 35h = 70(2h)(2h)

16h = 70(2h)(2h)

-70 = 20h

-7/2 = h

-3.5 = h
