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

Answer:

Step-by-step explanation:

A function cannot have multiple y values for one x value.

Option A lists the y values of -8 and 10 for the x value of -4. Therefore this is not a function.

Option B lists 0, 5, 10, AND 15 all for -1. This can't be a function either.

Option C does not have two of the same x values for different results. Although both 0 and 9 give you the answer of 1 for the y value, this is perfectly okay in a function. This is your answer.

The coleman family purchased a camper van for $38,000. the van is predicted to depreciate by about 15% each year. write an expon

forsale [732]

The exponential equation that can model the value of the camper van , in x years is y = 38000*(0.85)ˣ .

In the question ,

it is given that

the present value of the camper van (P₀) = $38000

given the depreciation rate is 15% each year (r)= -0.15

The future value y ,of the camper van can be given by the formula

y = P₀*(1 + r)ˣ

On putting the values , we get

y = 38000*( 1 - 0.15)ˣ

y = 38000*(0.85)ˣ

Therefore , The exponential equation that can model the value of the camper van , in x years is y = 38000*(0.85)ˣ .

For the equation 4+y=10.7 what step will you use to solve this

viva [34]

Answer:

y=6.7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

y+4=10.7

Step 2: Subtract 4 from both sides.

y+4−4=10.7−4

y=6.7

A backyard pool has a concrete walkway around it that is 3 feet wide on all sides. The total area of the pool and the walkway is

Sloan [31]

Answer:

$x \approx 21.080\,ft$ , $y = 29.080\,ft$

Step-by-step explanation:

The total area of the pool and the walkway is:

$(x + 6\,ft)\cdot (y + 6\,ft) = 950\,ft^{2}$

$(x + 6\,ft)\cdot (x + 14\,ft) = 950\,ft^{2}$

$x^{2} + 20\cdot x + 84\,ft^{2} = 950\,ft^{2}$

$x^{2} + 20\cdot x - 866\,ft^{2} = 0$

The roots of the second-order polynomial is:

$x_{1} \approx 21.080\,ft$ and $x_{2} \approx -41.081\,ft$

The only possible root is:

$x \approx 21.080\,ft$

The other dimension of the pool is:

$y = x + 8\,ft$

$y = 21.080\,ft + 8\,ft$

$y = 29.080\,ft$
