reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

Step-by-step explanation:

We need to find the reflection of f(x)=sqrt x over the y axis

So, reflection over y- axis

If the function f(x) is transformed over y-axis then the new function g(x) will be g(x)= f(-x)

So, finding reflection of f(x)=\sqrt{x} over the y axis we get:

g(x)=\sqrt{-x}

So, reflection of f(x)=\sqrt{x} over the y axis we get g(x)=\sqrt{-x}

The sum of a number and 3 times its reciprocal is -4.Find the number
Butoxors [25]

Answer:

x = -1 or x = -3

Step-by-step explanation:

x + 3/x = -4

x² + 3 = -4x

x² + 4x + 3 = 0

(x + 1) (x + 3) = 0

x = -1 or x = -3

check: (-1) + (3/-1) = -1 - 3 = -4

           (-3) + (3/(-3)) = -3 -1 = 14

Answer: A

Step-by-step explanation:

(f+g)(x) means f(x)+g(x). Since we are given f(x) and g(x), we cna add them together.

x+8+(-4x-3)

x+8-4x-3

-3x+5

Uhh help lol<br> 5.3x + y = 28.5 <br> 4.2x + 3.1y = 27.2<br> find x and y
navik [9.2K]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

y = -5.3x+28.5

Next, substitute y in the bottom equation.

4.2x + 3.1(-5.3x + 28.5) = 27.2

5.3x + y = 28.5

Simplify.

4.2x + -16.43x + 88.35 = 27.2

Combine like terms.

-12.23x + 88.35 = 27.2

Isolate x on one side.

-12.23x = -61.15

Isolate x.

x = 5

Substitute x into 5.3x + y = 28.5

5.3(5) + y = 28.5

Simplify.

26.5 + y = 28.5

Isolate y.

y = 2

x = 5 \\y = 2
