Answer:

63m^11 no^12

Step-by-step explanation:

Dont know if thats o or and zero but I solve it by using o..if it was a zero then comment that so I can redo it anyways heres the explanation

(7nm^5 o^2) × (-3m^3 o^5)^2

7m^5 no^2) ×(-3m^3 o^5) ^2

(7m^5 no^2) × (3m^3 o^5)^2

7m^5 no^2 × (3m^3 o^5) ^2

7m^5 no^2 × 9m^6 o^10

63m^11 no^12

What’s the inverse of the function f(x) = 2x - 10

erastovalidia [21]

The answer is: " f ⁻¹(x) = $\frac{x}{2}$ + 5 " .
____________________________________________________

Explanation:
____________________________________________________

Given the function: " f(x) = 2x − 10 " ; Find the "inverse function" .

Let "f(x)" be represented by "y" ; and rewrite:

y = 2x − 10 ;

Change the "y" to an "x" ; and change to "x" to a "y" ; as follows:
___________________________________________________
x = 2y − 10 ;

Now, rewrite this equation, in "slope-intercept form"; that is; "y = mx + b" ;

To do this, start by solving THIS equation for "y"; in terms of "x" ; with "y" as an "isolated variable" on the "left-hand side" of the equation;
___________________________________________________
We have:
___________________________________________________
" x = 2y − 10 " ;

Add "10" to each side of the equation; as follows:

x + 10 = 2y − 10 + 10 ;

to get:

x + 10 = 2y ;

↔ 2y = x + 10 ;

Now, divide each side of the equation by "2" ;
to isolate "y" on one side of the equation (as a single variable);
& to solve for "y" ;

→ 2y / 2 = (x + 10) / 2 ;

to get:

→ y = (x/2) + (10/2) ;

→ y = (x/2) + 5 ;

Now, rewrite the equation, by substituting: " f ⁻¹(x) " ; in place of the "y" ; to indicate that this function is an "inverse function; as follows:

→ " f ⁻¹(x) = $\frac{x}{2}$ + 5 " .

The answer is: " f ⁻¹(x) = $\frac{x}{2}$ + 5 " .

Please help me!!! I suck at math :((

If we know that line $AB$ is equal to line $AD$ , then this means that ∠ $ADB$ has to be equal to ∠ $ABD$ in order to form a closed triangle. All angle measures of a triangle add up to $180$ °, so use the equation: $2(35) + x = 180$ .
