Answer:

a) y=\frac{50}{x}

b) y=25 when x=2

Step-by-step explanation:

y=\frac{k}{x} since y varies inversely with x.

We need to find the constant, k.

Let's use a point (x,y) on the curve.

We are given an (x,y)=(5,10):

10=\frac{k}{5}

Multiply both sides by 5:

10(5)=k

50=k.

So the equation is:

y=\frac{50}{x}

What is y when x=2?

y=\frac{50}{2}

y=25

A = b(c + d) for b<br> Answer:<br> Written as an equation
madreJ [45]

Answer: B= A/(C+D)

Step-by-step explanation:

A = B(C+D)

Divide each side by B

A/B= C+D

Reciprocate both sides

B/A = 1/(C+D)

Now multiply each side by A

B = A/(C+D)

What expression is equivalent to 2.2-2.5?
Pani-rosa [81]
Hi <span>Camrynb10705oxknsv!
So let's take a look at the answers they give. A is 2.5 - 2.2 and all that is is switching the numbers so that isn't right. B they do addition instead of subtraction so that can't be right. C they do 2.2 + (-2.5) and when you add a negative number it's like subtraction because a negative number is under 0 and so your adding a number under 0 so you go down. So the answer is C.
If you need me to explain it different let me know. Hope this helps!</span>
