You would multiply 9x___ whatever the other number is witch is 4
SOLUTION
From the question, we are told that y varies inversely as x
This is mathematically written as

Now, we will remove the proportionality sign and replace it with equal to sign =
If we do this, we will intoduce a constant k

So we have the formula

We will substitute the values of x for 10 and y for 8 into the formula to get k, we have

Now, we will substitute k for 80 back into the formula to get the inverse function, we have

Hence the answer is option C
D. F(x)=x^2. That’s The quadratic parent function
Answer:
x=4 y=0
Step-by-step explanation:
You add the two equations together to get 3x=12. You derive x=4 and y=0 from that.
Answer:

Step-by-step explanation:
we have
<em>The equation of the first line</em>
------> equation A
<em>The equation of the second line</em>
------> equation B
Solve the system of equations by elimination
Multiply equation A by -4 both sides
--------> equation C
Adds equation B and equation C

<em>Find the value of x</em>
substitute the value of y


Multiply by 3 both sides


therefore
The solution to the system of equations is the point
