Answer:

For this case we have the following equation:

Ax - By = C

From here, we must clear the value of x.

Adding By on both sides:

Ax = By + C

Then, dividing both sides by A we have:

x =By +C/A

Answer:

x = By+C/A

x equals the quantity B times and plus C all over A

In which direction does the graph of the function shown below open?

sp2606 [1]

Answer:

D. Up

Step-by-step explanation:

When a parabola has the form $y=ax^2+bx+c$ , It is vertical (opens up or down).

Because the variable "x" is squared.

If "a" is positive, then the parabola opens up, but if it is negative, then the parabola opens down.

In this case you have the quadratic function:

$f(x) = 2x^2+5x-4$

Which can be rewritten as:

$y = 2x^2+5x-4$

Therefore, it is vertical, because it has the form: $y=ax^2+bx+c$

You can observe that the value of "a" is:

$a=2$

Then, since "a" is positive, the parabola opens up.

if a tree casts an 8 meter shadow, and the angle from the ground to the tree is 30 degrees, what is the approximate height of th

Virty [35]

Using SohCahToa, we can find the height of the tree. Let the tree height be h. 8m is adjacent to the 30° angle.
$\tan(30) = \frac{h}{8} \\ h = 8 \tan(30) \\ h = 4.62$
The answer is A) 4.6 m
