Answer:

y=sqrt((x+a)/-2b))

F=(5/9)C+32

Can't read the rest

Step-by-step explanation:

-2by^2=x+a

y^2=(x+a)/-2b

y=sqrt((x+a)/-2b))

F-32=(5/9)C

F=(5/9)C+32 (The actual Fahrenheit-Celcius formula)

NOTE: The other pictures cannot be opened.

Hi there! Im going to answer the subject of the formula x=a-2b^2

To find you need to subtract the a to the negative 2 which is going to be -1

So the actual Fahrenheit-Celcius formula is F=(5/9)C+32

Hope this helps

Graph the line with 3/4 slope<br> passing through the point (2,-2).

S_A_V [24]

Answer:

Step-by-step explanation

x1 = 2, y1 = -2 and m = 3/4

y - y1 = m(x - x1)

y - (-2) = 3/4(x - 2)

y + 2 = 3/4(x - 2)

Multiply each term by 4

4y + 8 = 3(x - 2)

4y + 8 = 3x - 6

4y = 3x - 6 - 8

4y = 3x - 14

What is the next term in the sequence below?

andreyandreev [35.5K]

Answer: Option a.

Step-by-step explanation:

1. The sequence shown in the problem is a Geometric sequence, because it has a common ratio. This means that when you multiply one of those numbers by the common ratio, you obtain the next number.

2. Then, you can calculate the common ratio as following:

$r=\frac{108}{-324}=-\frac{1}{3}$

3. Therefor, the next term is:

$(12)(-\frac{1}{3})=-4$
