Find the value of the variable

Answer:

x=6

Step-by-step explanation:

I would look at this triangle and notice that x can be solved by setting up a ratio.

I generally put the short side of the triangle on the top and the long side on the bottom

4/x = x/9

You then cross multiply to get 36=x^2, or +-6=x

A length of a triangle cannot be negative, so we are left with the answer x=6

Kali spent half of her weekly allowance on clothes. To earn more money her parents let her clean the gutters for $9. What is her

Ber [7]

So to find the answer to this, you have to consider that $\frac{1}{2} x + 9 = 13$ - half because half the pocket money (x) was spend on clothes, then plus 9 because that's how much extra she gained and 13 because that was the result of all the changes.

To solve this, first subtract 9 from both side, which leaves you with $\frac{1}{2} x = 4$ and $\frac{1}{2} x$ is the same as $\frac{1x}{2}$ , so to solve this, multiply both sides of the equation by two, resulting in $x = 8$ . SO from this we can conclude that the weekly allowance is $8

If f (x) = StartRoot one-half x minus 10 EndRoot + 3, which inequality can be used to find the domain of f(x)?

just olya [345]

The inequality that represents the domain of the function is $\frac 12x - 10 \ge 0$

<h3>How to determine the domain?</h3>

The function is given as:

$f(x) = \sqrt{\frac 12x - 10} + 3$

Set the radicand greater than or equal to 0

$\frac 12x - 10 \ge 0$

Multiply through by 2

x - 20 ≥ 0

Add 20 to both sides

x ≥ 20

Hence, the domain of the function is x ≥ 20
