What is the solution of the equation 3/4x +5 = -9?<br> 16<br> 3<br> Done
Licemer1 [7]
X=-56/3

multiply everything by 4 to cancel the fraction which will give you
3x+20=-36

then combine like terms to get
3x=-56

then divide to get x by itself to get

x=-56/3

since this is a weird decimal, leave it as an improper fraction

Please help ASAP!!!!!!!!!!!
Effectus [21]

Answer:

x = 3.76 ft

Step-by-step explanation:

To find the missing side, "x", solve using proportions.

In similar polygons, the 'new' polygon was created by multiplying every side of the 'old' polygon by the same number. Every side was multiply by the <u>scale factor</u>, "k", which tells you how much a polygon grew (k>1) or shrunk (0<k<1).

Therefore, if you divided the pairs of corresponding sides, they would be equal.

From the diagram, you can tell that the following sides correspond:

CB ~ GF

AB ~ EF

<u>Use the proportion</u>

\frac{EF}{AB} = \frac{GF}{CB}

\frac{x}{6ft} = \frac{3.3ft}{5ft}      Substitute values from diagram

6ft*\frac{x}{6ft} = 6ft*\frac{3.3ft}{5ft}       Multiply both sides by 6 ft

x = \frac{6ft*3.3ft}{5ft}        "x" is isolated. Multiply fraction by combining into numerator

x = \frac{19.8ft}{5ft}        Solved numerator. Divide for decimal answer.

x = 3.76ft

The value of 'x' is 3.76 ft.

Complete the steps in order to write the inverse of f(x) = x + 5 1. = x + 5 2. = y + 5 3. = y 4. = x – 5
Allisa [31]
Hi there!

f(x) = x + 5

1. y = x + 5
Switch places from x and y.

2. x = y + 5
Subtract 5.

3. x - 5 = y
Switch sides.

4. y = x – 5
Now we've found our answer.

~ Hope this helps you!

What is the slope of a line perpendicular to the line whose equation is 3x+6y=-183x+6y=−18. Fully reduce your answer.
schepotkina [342]

Answer:

2

Step-by-step explanation:

The given equation of line is

3x+6y=-18

We need to find the slope of a line which is perpendicular to the given line.

The given equation can be rewritten as

3x+6y+18=0      ...(i)

If a line is defined as ax+bx+c=0, then the slope of the line is  

m=-\dfrac{a}{b}

In equation (i), a=3, b=6 and c=18. So, slope of the line is

m_1=-\dfrac{3}{6}=-\dfrac{1}{2}

Let m_2 be the slope of perpendicular line.

We know that product of two perpendicular line is -1.

m_1\cdot m_2=-1

(-\dfrac{1}{2})\cdot m_2=-1

Multiply both sides by -2.

m_2=2

Therefore, the slope of perpendicular line is 2.
