X^2 + 12x = -6

x^2 + 12 x + 6^2 = -6 + 6^2

(x + 6)^2 = - 6 + 36

(x +6)^2 = 30

In the first step I had to add 6^2 = 36. The answer is option B. 36.

Describe the slope of the line<br> Find the slope
Dmitry_Shevchenko [17]

Answer:

Question one: Zero slope
Question two: m=\frac{0}{4}

Step-by-step explanation:

Given the following questions:

<u>Question one:

</u>The following line is what you call a "zero slope." Zero slopes are lines that are neither decreasing or increasing and remain at a constant or just a straight line.

Question two:

Point A = (-2, -3) = (x1, y1)
Point B = (2, -3) = (x2, y2)

Using the formula for slope or rise over run we will solve and find the slope of this line.

m=\frac{y2-y1}{x2-x1}
m=\frac{-3--3}{2--2} =\frac{0}{4}
m=\frac{0}{4}

The slope of this line is "0/4."

Hope this helps.

Ben needs 1 3/8 feet of fabric to make one banner. How many banners can he make from 4 1/2 yards of fabric?
skelet666 [1.2K]

Answer:

x = 9.818

x≈10

The number of banners that can be made are 10

Step-by-step explanation:

We can use the knowledge of proportion to solve this.

First we need to convert yard to feet.

  1  yard      = 3 foot

4 1/2 yard    = y

cross-multiply

y =  4 1/2  ×  3

    =9/2  ×   3

y = \frac{27}{2} feet

This implies 4 1/2 yards =  \frac{27}{2} feet

Let x be the numbers of banners needed to make from 4 1/2 yards of fabric.

1 3/8 feet  = 1 banner

\frac{27}{2}  feets    =    x

cross multiply

1 3/8 × x =  \frac{27}{2}

\frac{11x}{8}  =  \frac{27}{2}

cross-multiply

22x = 216

Divide both-side of the equation by 22

22x/22 = 216/22

x = 9.818

x≈10

The number of banners that can be made are 10

Suppose P(C/D)=0.34, P(D)=0.11 , and P(D/C)=0.09. What is P(C) rounded to two decimal places?
Olegator [25]

So C/D=.34 And D=.11, now just plug D into the first equation.

C/.11=.34 Divide by .11

C=3.09090909

Now this rounded two decimal places is 3.09!

Hope this helps
