A. The variable would be the number of miles ran, which will be X.

B. Steve ran X miles and Kevin ran X + 4, the two expressions are: X and X +4

C. Add both expressions together to equal the total miles:

The equation would be: X + X+4 = 26

D. solve:

x + x+4 = 26

Combine like terms:

2x +4 = 26

Subtract 4 from both sides:

2x = 22

Divide both sides by 2:

x = 22/2

x = 11

E: Check answer:

Steve ran X miles = X = 11, Steve ran 11 miles.

Kevin ran 4 more than Steve ( x +4) = 11+4 = 15 miles

The sum was 26: 11 + 15 = 26

26 = 26 The answer checks out to be true.

What is the inverse of this function? (Function in photo)

valkas [14]

Given:

The function is

$f(x)=-\dfrac{1}{2}\sqrt{x+3},x\geq -3$

To find:

The inverse of the given function.

Solution:

We have,

$f(x)=-\dfrac{1}{2}\sqrt{x+3}$

Put f(x)=y.

$y=-\dfrac{1}{2}\sqrt{x+3}$

Interchange x and y.

$x=-\dfrac{1}{2}\sqrt{y+3}$

Isolate the variable y.

$-2x=\sqrt{y+3}$

$(-2x)^2=y+3$

$4x^2-3=y$

$y=4x^2-3$

Putting $y=f^{-1}(x)$ , we get

$f^{-1}(x)=4x^2-3$

For $x\geq -3$ ,

$x+3\geq 0$

$\sqrt{x+3}\geq 0$

$-\dfrac{1}{2}\sqrt{x+3}\leq 0$

$f(x)\leq 0$

It means for function $f(x)\leq 0$ and for inverse function $x\leq 0$ because the range of the function is the domain of inverse function.

Therefore, $f^{-1}(x)=4x^2-3$ for $x\leq 0$ .

Dafna1 [17]

Answer:

Step-by-step explanation:

$n,\ n+2-\text{two consecutive even integers}\\\\\text{The equation:}\\\\n+(n+2)=-42\\\\n+n+2=-42\qquad\text{subtract 2 from both sides}\\\\2n=-44\qquad\text{divide both sides by 2}\\\\n=-22\\\\n+2=-22+2=-20$
