16 = 2/3f
16 ÷ 2/3 = f
16 × 3/2 = f
48/2 = f
24 = f
Answer:
(0,-2)
Step-by-step explanation:
one way to solve...
3x - y = 2 --> *4
-2x + 4y = -8
multiply the first equation by 4
12x - 4y = 8
-2x + 4y = -8
-----------------
10x = 0
x = 0
y = -2
this method is called elimination
another way to solve...
3x - y = 2 simplify for y to get y = 3x - 2
-2x + 4y = -8 substitute y into this equation to solve for x
-2x + 4(3x - 2) = -8
-2x + 12x - 8 = -8
10x = 0
x = 0
y = -2
substitution
alsoo if there are options, just plug in the numbers to the correct variables
Answer:




With 



So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
Step-by-step explanation:
For this case we know the following function:

We can begin the zeros or the values where the function is 0 like this:

And solving for x we got:

Now we can rewrite the expression like this:

And we can find the position for the vertex at x with this formula:

With 
And replacing we got:

And then with the coordinate of x for the vertex we can find the coordinate of y replacing the value of x obtained for the vertex.

Then we can find the intercept using the value of x=0 and replacing into the function we got:

So then the x intercept would be (0,-5). And finally we can graph the function as we can see in the figure attached.
