What is the image of (2,3)(2,3) after a reflection over the line y=-xy=−x?

Mathematics
1 answer:
otez555 [7]3 years ago
4 0

Answer:

After the reflection over the line  y = -x, the image of the point is: (-3,-2)

Step-by-step explanation:

When a given point is reflected over a line the point only changes place but the distance between the point and the line remains same.

Let (x,y) be a point on the plane

and

y = -x be a line on the plane

When a point is reflected over a line y = -x , the coordinates of the point are exchanged which means x becomes y and y becomes x and both are negated

So (x,y) will become (-y,-x)

Given point is:

(2,3)

After the reflection over the line  y = -x, the image of the point is: (-3,-2)

Find the circumference and area of a circle<br>with a radius of 5 feet.​
iVinArrow [24]

Circumference = 2(pi)r

Area = (pi)r^2

r = 5

5 * 2 = 10

Circumference = 10π

5 * 5 = 25

Area = 25π

Using 3.14 as pi substitute:

5 * 3.14 = 15.7

15.7 * 2 = 31.4

Circumference = 31.4

5 * 5 = 25

25 * 3.14 = 78.5

Area = 78.5

At time t=0, water begins to drip out of a pipe into an empty bucket. After 56 minutes, 8 inches of water is in the bucket. what
Sergio [31]

Answer:

W = (1/7) t

Step-by-step explanation:

At t = 0, W  =  0

At t = 56 minutes , W = 8 inches

W = k*t    The y intercept = 0 because t = 0 W = 0

8 inches = k * 56 minutes

k = 8 / 56

k = 1/7 inches / minute

W = (1/7) t

How can you distinguish if the solution is one value, all real numbers, or no solutions?
murzikaleks [220]

Answer:

If x can only have one answer, then the solution is one value. If x can be all real numbers, then the solution is all real numbers. And if x doesn't have an answer then it has no solution.

Step-by-step explanation:

For example:

One value: 7 + x= 10 => x= 3

All real numbers: 0x=0 => x can be all real numbers

No solutions: 7x=6x => no solutions

Given the function f(x)=4x-9, evaluate and simplify the following f(-6) and f(4)
saveliy_v [14]

Answer:

<h2>f(-6) = -33, f(4) = 7</h2>

Step-by-step explanation:

f(x)=4x-9

f(-6), f(4)

Put x = -6 and x = 4 to the equation of the function:

f(-6)=4(-6)-9=-24-9=-33\\\\f(4)=4(4)-9=16-9=7
