We must require that [tex]x \ne -12[/tex] and [tex]x \ne 3[/tex] to avoid having 0 in the denominator. This is why choice D is the answer.

The amount of carpet needed to make the hole is 44 ft²

Area is the amount of space that a two dimensional object or figure occupies.

The area of the big rectangle = length * width = 12 * 4 = 48 ft²

Area of hole = length * width = 2 * 2 = 4 ft²

Amount of carpet required = 48 ft² - 4 ft² = 44 ft²

The amount of carpet needed to make the hole is 44 ft²

Answer:

8 bulbs

Step-by-step explanation:

In the model, each + represents a dollar

4 +s for the shipping cost, 20 +s for the total cost.

Therefore we have 2x (since each bulb is $2) + 4 = 20

2x = 16

x = 8

Step-by-step explanation:

x is the number of bulbs.

We have $2x + $4 = $20.

=> $2x = $16, x = 8.

Hence Sheila can order 8 flower bulbs.

Answer:

41°

Step-by-step explanation:

Using cosine rule : since the 3 sides are given

p = 6 ; q = 4 ; r = 5

q² = p² + r² - 2prCosQ

2prCosQ = p² + r² - q²

COS Q = (p² + r² - q²) / 2pr

Cos Q = (6² + 5² - 4²) / 2*6*5

Cos Q = 45 / 60

Cos Q = 0.75

Q = Cos^-1 (0.75)

Q = 41.409622

Q = 41° ( nearest degree)

Answer:

Step-by-step explanation:

Answer:

We know that the function IxI is such that:

IxI = x if x ≥ 0

IxI = -x if x < 0.

In this case, we have:

A = I3x - 6I + 2

If we do the same as above, we can write:

A = (3x - 6) + 2       if (3x - 6) ≥ 0

Let's look at the condition in the right, let's isolate the variable:

(3x - 6) ≥ 0

3x ≥ 6

x ≥ 6/3 = 2

Then the condition:

(3x - 6) ≥ 0

is equivalent to:

x ≥  2

Then we can write:

A = (3x - 6) + 2      if  x ≥ 2

If we simplify it further, we get:

A = 3x - 6 + 2        if  x ≥ 2

A = 3x - 4               if  x ≥ 2

This is what we wanted to prove.    

Answer:

x = -1/2

Step-by-step explanation:

2x + 4y = 13

3x + y = 2    (you can multiply this equation by -4 in order to eliminate the y-term)

-4(3x + y = 2)  =  -12x - 4y = -8

                        +  2x + 4y = 13

-10x = 5

x = -5/10 or -1/2

x(-1/2) + 4y = 13

-1 + 4y = 13

4y = 14

y = 14/4 or 7/2 or 3 1/2

Answer:

The formula for the nth term of the sequence is:

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Step-by-step explanation:

Given the sequence

6, -6, 6, -6

A geometric sequence has a constant ratio r and is defined by

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Computing the ratios of all the terms of the adjacent terms

[tex]\frac{-6}{6}=-1,\:\quad \frac{6}{-6}=-1,\:\quad \frac{-6}{6}=-1[/tex]

The ratio of all the adjacent terms is the same and equal

so

r = -1

so substituting r = -1 and [tex]a_1=6[/tex] in the geometric sequence

[tex]a_n=a_1\cdot r^{n-1}[/tex]

[tex]a_n=6\left(-1\right)^{n-1}[/tex]

Thus, the formula for the nth term of the sequence is:

[tex]a_n=a_1\cdot r^{n-1}[/tex]

Answer:

Assuming you mean width not breadth (What is that)

The width would be: 35m

Step-by-step explanation:

Now its pretty staight forward

We know that the length is 42m

And the permineter is 154m

We know that the perimeter is the 2 widths and 2 lengths all added up to each other (basically very side added up)

An eaution could be used like, 2w+2l=154

We know length is 42 so

2w+2*42=154

Now just solve for W

2*42=84

2w+84=154

154-84= 70

70=2w

70/2=35

w=35

Answer:

y = 5.5x + 79.5

Step-by-step explanation:

Given that:

Weight gained after 11 months = 140 kg

Rate of weight gain = 5.5kg per month

Weight in kg after x months = y

Representing the equation in the form:

y = mx + c

m = rate of water gain = slope = 5. 5

.the intercept c, can be obtained thus ;

x = 11 ; y = 140

140 = 5.5(11) + c

140 = 60.5 + c

140 - 60.5 = c

79.5 = c

Hence,

y = 5.5x + 79.5

To answer this, we need to understand something

Firstly is that we have dotted lines of the inequality line does not have an equal

to

And also, the solution is directly related to the inequality sign. If it states greater than, solution will be greater than (above the line). If it states less than, solution will be less than (below the line)

So let us take the inequalities one after the other from left to right

1. solid line and below the line

2. dotted lines and above the line

3. solid line and above the line
