3x+20=100

Now you would need to move the constant to the right side and change within it’s sign

3x=100-20

Now you would subtract the numbers so for 100-20 would give you 80

So now you then do 3x=80

But if you want to divide the equation, divide it by both sides by 3

Which would give you x=80/3, x=26.6 or x=26 2/3

Which represents the reflection of f(x)=sqrt x over the y axis

zloy xaker [14]

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 $g(x)=\sqrt{-x}$

Combining like terms with negative coefficients -3x-6+(-1)

Verdich [7]

Step-by-step explanation:

Hey there!!

You can simply do it.

Here, -3x -6 +(-1) is given.

In this question, the like term is "-6" and "-1" because both are coefficients.

Combine it.

= -3x -6 -1 { as (-) (+)=(-)}

= -3x -7 { when there is (-) sign then it will be added but the sign would be minus}.

Or you can also write it as -( 3x+7). {taking (-) common}

Hope it helps...
