Answer:

$f = \frac{2}{5} d - 6$

Step-by-step explanation:

You are solving for the variable, f. Note the equal sign, what you do to one side, you do to the other. Isolate f.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

First, subtract 2d from both sides.

2d (-2d) - 5f = 30 (-2d)

-5f = -2d + 30

Next, to isolate the variable, f, divide -5 from both sides:

(-5f)/-5 = (-2d + 30)/-5

f = (-2d + 30)/-5

f = (2/5)d - 6

$f = \frac{2}{5} d - 6$ is your answer.

Hope this helps!

Answer: 5/2f+15

Step-by-step explanation:

2d−5f+5f=30+5f

Then,

2d=5f+30

Next,

2d/2 =5f+30/2

What is the equation of the following line? Be sure to scroll down first to see

Rom4ik [11]

<h2>Answer:</h2>

-1/3x

<h2>Step-by-step explanation:</h2><h3>Known :</h3>

x1 = -3
x2 = 0
y1 = 1
y2 = 0

<h3>Asked :</h3>

Correct line equation

<h3>Solution :</h3>

We can find the straight line equation using this formula,

$\frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1}$

Insert all we know inside the formula,

$\frac{y-1}{0-1} = \frac{x-(-3)}{0-(-3)}\\\frac{y-1}{-1} = \frac{x +3}{3}\\$

Use cross multiplication,

3(y - 1) = -1(x + 3)\

3y - 3 = -x - 3

3y = -x - 3 + 3

3y = -x

y = -1/3x

<h3>Conclusion :</h3>

The correct equation is y = -1/3x

Algebra Test pls help

Answer:

Option 3

y + 16 = 8(x + 2)

Step-by-step explanation:

<h3><u>Given</u>;</h3>

x = 2, 4, 6, 8
y = 16, 32, 48, 64

Now, Put the values in equation 1

y – 16 = 8(x – 2)

For x = 2 and y = 16

y – 16 = 8(x – 2)

16 – 16 = 8(2 – 2)

0 = 8

Here, L.H.S ≠ R.H.S

So, Option 1 is incorrect

Now, Put the values in equation 2

y – 16 = 8x – 2

For x = 2 and y = 16

y – 16 = 8x – 2

16 – 16 = 8(2) – 2

0 = 14

Here, L.H.S ≠ R.H.S

So, Option 1 is incorrect

Now, Put the values in equation 3

y + 16 = 8(x + 2)

For x = 2 and y = 16

y + 16 = 8(x + 2)

16 + 16 = 8(2 + 2)

32 = 8(4)

32 = 32

Here, L.H.S = R.H.S

Check other values of x and y

For x = 4 and y = 32

y + 16 = 8(x + 2)

32 + 16 = 8(4 + 2)

48 = 8(6)

48 = 48

Here, L.H.S = R.H.S

For x = 6 and y = 48

y + 16 = 8(x + 2)

48 + 16 = 8(6 + 2)

64 = 8(8)

64 = 64

Here, L.H.S = R.H.S

For x = 8 and y = 64

y + 16 = 8(x + 2)

64 + 16 = 8(8 + 2)

80 = 8(10)

80 = 80

Here, L.H.S = R.H.S

Thus, The equation 3 in point-slope from gives the plant's height at any time.

What is the equation of the line, in general form, that passes through point (-1, -1) and is parallel to the line whose equation

lara31 [8.8K]

ANSWER

$x + y + 2 = 0$

EXPLANATION

The given line passes through;

(-1,-1) and it is parallel to x + y = 3.

This line given to us can be rewritten as

y=-x+1

It has slope m=-1.

The line parallel to this line also has slope m=-1.

We obtain the equation of the line using the formula:

$y-y_1=m(x-x_1)$

We substitute the slope and the point to obtain:

$y - - 1 = - 1(x - - 1)$

$y + 1 = - 1(x + 1)$

$y = - x - 1 - 1$

The equation of the line is

$x + y + 2 = 0$
