V^2-8v=0 solving quadratic equation

Mathematics

1 answer:

solong [7]2 years ago

8 0

Answer:

v = 0, or v = 8

Step-by-step explanation:

The quadratic can be factored, then the zero product rule applied.

v^2 -8v = 0

v(v -8) = 0

A product will be zero when any of the factors is zero. So, the solutions are values of v that make the factors be zero.

v = 0

v -8 = 0 . . . ⇒ . . . v = 8

Kyle notices that the number of likes he receives each day on his social media page is a function. He decides to create a graph

12345 [234]

Answer:

B) y=12x

Step-by-step explanation:

We are given with the coordinates $(0,0) , (1,12) \ and \ (2,24)$

Where $x$ represents the number of days.

$y$ represents the number of likes she got.

To model the equation using Kyle's data we find the slope using the given coordinate.

Let us say $(0,0) \ as \ (x1 , y1)$ and $(1,12) \ as \ (x2,y2)$

Slope $(m)$ formula , $m=\frac{(y2-y1)}{(x2-x1)}$

Plug in the above points now, we get

$m=\frac{(12-0)}{(1-0)} =\frac{12}{1} =12$

Now we use the point-slope formula, $(y-1)= m(x-x1)$

Plugging the corresponding values.

$(y-0)= 12(x-0)\\y=12x$

Thus option is B is the correct answer.

HELP ME PLEASE ITS DUE TODAY!!!!

Stells [14]

Step-by-step explanation:

$- 5 - ( - 4) = - 5 + 4 = - 1 \\ - 4 - ( - 5) = - 4 + 5 = 1 \\ - 4 - (5) = - 4 - 5 = - 9 \\ 4 - ( - 5) = 4 + 5 = 9$

Therefore ranking them from least to most:

$- 4 - (5) \\ - 5 - ( - 4) \\ - 4 - ( - 5) \\ 4 - ( - 5)$

For which independent value do the equations generate the same dependent value? y1=6x-16 , y2=3x-10

Nikitich [7]

The question asks which x-value gives the same y-value for both equations, so if you need the ys to be equal, you can set both equations equal to each other, giving you 6x-16=3x-10. Now, solve for x. 6x-16=3x-10, subtract 3x and add 16, 3x=6, divide 3, x=2. Your answer is x=2.
