How do u solve for y

1 answer:

8 0

If you are talking about y as in y = mx + b then i can help you.
Let’s use this example:
3x + 4y + 2 = 16
What you first need to do is get y alone on one side of the equation. The way we do this is by subtracting 2 from both sides. That gives us 3x + 4y = 14
After this let’s move the x over to the other side into point slope form. 4y = -3x + 14
Now just divide everything by 4.
The answer is y = -3/4x + 7/2

Use a graphing utility to approximate (to two decimal places) any relative

iogann1982 [59]

Answer:

Relative minima at $(-\frac{7}{2} , -\frac{49}{4} )$ , and relative maxima DNE.

Step-by-step explanation:

The given function is f(x) = x (x + 7) ...... (1)

We have to calculate the relative maxima and relative minima at point (x, y).

Rearranging the function given above we get.

$y= x^{2} +7x = (x + \frac{7}{2} )^{2} -\frac{49}{4}$

⇒ $y+ \frac{49}{4} = (x + \frac{7}{2} )^{2}$

Now, this is an equation of parabola having vertex at $(-\frac{7}{2} , -\frac{49}{4} )$ and the axis is parallel to positive Y-axis.

Therefore, the function(1) has a relative minima at $(-\frac{7}{2} , -\frac{49}{4} )$ , and the relative maxima DNE. (Answer)

What is 9. 24 repeating as a mixed number in simplest form?

Serga [27]

The recurring decimal number 9.2424... expressed in mixed number is $9\frac{24}{99}$

In the given decimal number, 2 is the digit at the tenth place and 4 is the digit at the hundredth place.

The fraction part $\frac{24}{99}$ in the simplest form is $\frac{8}{33}$

The whole number part is 9.

Therefore, the number 9.2424... as a mixed number in the simplest form is $9\frac{8}{33}$

a fan has five equally spaced blades. suppose you line up two fans directly on top of each other. What is the least number of de

Irina18 [472]

Answer:

72°

Step-by-step explanation:

There are 5 blades, equally spaced. So the angle between adjacent blades is 360° / 5 = 72°. So you can rotate the fan 72° and the blades will align again.
