(if you need the  value of x)

180-48=132

formula for an for the arithmetic sequence.
ah = -1, d = -7

Answers

Answer:

The formula for the arithmetic sequence will be:

[tex]a_n=-7n+6[/tex]

Step-by-step explanation:

Given

a₁ = -1d = -7

We know that we can get the next term of the Arithmetic sequence by taking the current term and adding the common difference.

so

a₂ = a₁ +  d

    = -1 + (-7)          ∵ a₁ = -1

    = -1 - 7

     = -8

similarly,

a₃ = a₂ + d

     = -8 + (-7)

     = -8 - 7

      = -15

and so on

Thus, the Arithmetic sequence becomes

a₁, a₂, a₃, ...

-1, -8, -15, ...

as

a₁ = -1d = -7

Therefore, An arithmetic sequence has a constant difference d and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting a₁ = -1 and d = -7

[tex]a_n=-7\left(n-1\right)-1[/tex]

[tex]a_n=-7n+6[/tex]

Hence, the formula for the arithmetic sequence will be:

[tex]a_n=-7n+6[/tex]

Using angle sum property of triangle ,

∠OBC + ∠OCB + ∠BOC = 90°

Answers

Problem 1

Answers:

Domain: [tex]-3 \le x < 5[/tex]

Range: [tex]-4 < y \le 3[/tex]

--------------------

Explanation:

The domain is the set of allowed x inputs of a function. The smallest x value we can use is x = -3 (note the very left-most point of the graph). The right-most point involves x = 5, but we can't actually use this x value due to the open hole. So that's why we don't have "or equal to" attached to the 5.

The range is the set of possible y outputs. The lowest we can go is y = -4, but we don't include this as part of the range. The largest y can get is y = 3. So the range is [tex]-4 < y \le 3[/tex]

===========================================

Problem 2

Answers:

Domain: [tex]-2 < x < 4[/tex]

Range: [tex]-2 < y < 5[/tex]

--------------------

Explanation:

We use the same idea as in problem 1. Both endpoints are open holes, so we don't include them as part of the domain and range. For instance, we can't include x = 4 but we can get closer and closer to it. The same idea applies to the range as well.

===========================================

Problem 3

Answers:

Domain:  [tex]1 \le x \le 4[/tex]

Range: [tex]-4 \le y \le -1[/tex]

--------------------

Explanation:

The same idea applies as used earlier. This time we include both endpoints, so we have "or equal to" as part of each inequality sign.

What is the length of PR?
A: 13.5 inches
B: 7.5 inches
C: 10.5 inches
D: 9.5 inches

Answers

Answer:

The correct option is;

C: 10.5 inches

Step-by-step explanation:

In triangle ΔPQR the given parameters are;

The length of [tex]\overline {QP}[/tex] = 19.5 in.

The length of [tex]\overline {QR}[/tex] = 7.5 in.

In triangle ΔVWX, the given parameters are;

The length of [tex]\overline {WV}[/tex] = 13 in.

The length of [tex]\overline {WX}[/tex] = 5 in.

The length of [tex]\overline {VX}[/tex] = 7 in.

Given that we have;

[tex]\dfrac{\overline {QP}}{\overline {WV}} = \dfrac{19.5}{13} = 1.5 , \ \dfrac{\overline {QR}}{\overline {WX}} = \dfrac{7.5}{5} = 1.5[/tex]

The ratio of the corresponding sides of triangle ΔPQR and triangle ΔVWX are equal, therefore ΔPQR is similar to ΔVWX, from which we have for the corresponding sides, [tex]\overline {PR}[/tex] and [tex]\overline {VX}[/tex];

[tex]\dfrac{\overline {PR}}{\overline {WV}} = \dfrac{\overline {PR}}{\overline {7}} = 1.5[/tex]

∴ [tex]\overline {PR}[/tex] = 7 × 1.5 = 10.5

The length of [tex]\overline {PR}[/tex] = 10.5 inches

Lola gets two 20-minute breaks at work each day. She works 5 days a week. How much time does she spend on break each week?
Group of answer choices

Answers

Answer:

200 minutes / 3 hours & 20 minutes.

Step-by-step explanation:

This is quite simple.

First, since we know that Lola takes two 20 minute breaks at work each day, let's multiply 20 and 2.

20 × 2 = 40

This means she is on break for a total of 40 minutes each day.

Finally, let's take that 40 and multiply it by 5.

40 × 5 = 200

This means she spend 200 minutes (3 hours & 20 mins) on break each week.

200 minutes or 3 hrs and 20 mins

Select each pair of expressions that are equivalent. 3x + 14 – x + 112 and 4x + 134 2 + 6x and 2(3x + 1) 3(x + 1) – (1 – x) and 2x + 3 3x and 4(x + 1) – x – 4 5.5 + 2.2x + 3.8x – 4.1 and 1.4 + 6x

Answers

Answer:

Options (2), (4) and (5)

Step-by-step explanation:

Option 1

(3x + 14 - x + 112) and (4x + 134)

Since, (3x + 14 - x + 112) = (3x - x) + (12 + 112)

                                      = 2x + 124

Therefore, (3x + 14 - x + 112) ≠ (4x + 134) [Not equivalent]

Option 2

(2 + 6x) and 2(3x + 1)

2(3x + 1) = (6x + 2)

Therefore, (2 + 6x) = (6x + 2) [Equivalent]

Option 3

3(x + 1) - (1 - x) and (2x + 3)

Since, 3(x + 1) - (1 - x) = 3x + 3 + x - 1

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

                                  = 4x + 2

Therefore, (2x + 3) ≠ (4x + 2) [Not equivalent]

Option 4

3x and 4(x + 1) - x - 4

Since, [4(x + 1) - x - 4] = 4x + 4 - x - 4

                                   = (4x - x) + (4 - 4)

                                   = 3x

Therefore, 3x = [4(x + 1) - x - 4] [Equivalent]

Option 5

(5.5 + 2.2x + 3.8x - 4.1) and (1.4 + 6x)

Since, (5.5 + 2.2x + 3.8x - 4.1) = (2.2x + 3.8x) + (5.5 - 4.1)

                                                 = (6x + 1.4)

Therefore, (1.4 + 6x) = (6x + 1.4) [Equivalent]

$18 if it has 9 attendees. If there are 26 attendees, how much will the corporate team-building event cost? Solve using unit rates.

Answers

Answer:$52

Step-by-step explanation: I would first set up an equation. 9a=18 (a means attendees). Then, I would divide both sides by 9 to isolate the a. I would get a=2. So now I know that 1 attendee costs 2 dollars. If I want to find the cost for 26 attendees, all I would have to do is multiply both sides of the equation a=2 by 26. I would get 26a=52. So, 26 attendees cost $52. I hope this helps you out!

Answers

Answer: 18b + 2

Step-by-step explanation:

Length: 2b + 4

Width: 7b + 2

I assumed the garden is a rectangle shape since the length and width are different.

Perimeter = 2( L + w)

Then we just plug the values in.

2 (2b + 4 + 7b + 2)

2 (9b + 6) = 18b + 12

So, the equation for the perimeter of Jimmy's garden will be 18b + 2.

Answer:

Step-by-step explanation:

Given

6( [tex]\frac{3x}{2}[/tex] - 4 ) = 30 ( divide both sides by 6 )

[tex]\frac{3x}{2}[/tex] - 4 = 5 ( add 4 to both sides )

[tex]\frac{3x}{2}[/tex] = 9 ( multiply both sides by 2 to clear the fraction )

3x = 18 ( divide both sides by 3 )

x = 6

Answer:

x = 6

Step-by-step explanation:

[tex]6( \frac{3x}{2} - 4) = 30[/tex]

Dividing both the sides by 6 ,

[tex] = > \frac{6( \frac{3x}{2} - 4) }{6} = \frac{30}{6} [/tex]

[tex] = > \frac{3x}{2} - 4 = 5[/tex]

Adding 4 on both the sides ,

[tex] = > \frac{3x}{2} - 4 + 4 = 5 + 4[/tex]

[tex] = > \frac{3x}{2} = 9[/tex]

Multiplying both the sides by 2 ,

[tex] = > \frac{3x}{2} \times 2 = 9 \times 2[/tex]

[tex] = > 3x = 18[/tex]

Dividing both the sides by 3,
