Answer:

Domain: [-4, ∞)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, our line's x-values span from -4 to infinity. Since -4 is closed dot, it is inclusive in the domain:

Interval Notation: [-4, ∞)

Interval Notation: y ≥ -4

Answer: x=11 or x=-11

Step-by-step explanation:

Answer:x=11 or x=-11

Step-by-step explanation:  First, Use the FOIL method.

(x+5)(x+4)=9x+141

First: [tex]x^{2}[/tex]

Outer: 4x

Inner:  5x

Last:  5x4=20

Combine Like terms and write in standard form: [tex]x^{2}[/tex]+9x+20

Set up new equation:[tex]x^{2}[/tex]+9x+20=9x+141

Subtract 9x from both sides: [tex]x^{2}[/tex]+20=141

Subtact 20 from both sides: [tex]x^{2}[/tex]=121

Sqr root 121: [tex]\sqrt{121}[/tex] =11

Remeber a sqr root of a positive number can be positive and negative so x= 11 or -11

Answer:

Step-by-step explanation:

Angle on a straight line = 180°

Given Angles :

60°g and 80°g

Let the unknown angle be x

[tex]x + 60 + 80 = 180 \\ x + 140 = 180 \\ x = 180 - 140 \\ x= 40[/tex]

Answer:

50

Step-by-step explanation:

60% of 50 is 30

Answer:

Step-by-step explanation:

Recognize that this is a 30-60-90 triangle.  

Write and solve an equation of ratios:

 x         1

------ = ------- (which is the tangent of 30°)

√2       √3  

Then √3*x = √2, and so:

       √2

x = ----------

        √3

Rationalize this as follows:  

      √2*√3        √6

x = ------------- = ------

            3-            3

Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112

Step-by-step explanation:

alternate exterior angles have the same measure

Answer:

Step-by-step explanation:

You make 4 into 4/1 and then raise it to 8/2. then you divide across, if im right.

Answer:

4 is the same things as 4/1. and we know that dividing by a fraction is the same thing as multiplying by its reciprocal. so 5/2 times 1/4. just multiply straight across and you get 5/8

Answer:

$6.83

Step-by-step explanation:

A brownie costs $3.45, an ice cream costs $2.43, and a cookie costs $0.95. So $3.45 + $2.43 + $0.95 = $6.83.  If you need to know the change if they paid with $10.00 also  . . . That would be $10.00 - $6.83 = $3.17 change.

Answer:

  7 1/8 yd

Step-by-step explanation:

The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.

  P = 3·(2 3/8 yd) = 6 9/8 yd  . . . . .  9/8 = 1 1/8

  P = 7 1/8 yd

The perimeter is 7 1/8 yards.

Answer:

[tex]perimeter \: of \: the \: triangle \\ = 2 \frac{3}{8} +2\frac{3}{8} + 2 \frac{3}{8} \\ = 3 \times 2 \frac{3}{8}\\= 3 \times \frac{19}{8} \\ = \frac{57}{8} \: yd \\ = 7 \frac{1}{8} \: yd[/tex]

Answer:

0.172 ; 0.0884 ; 0.9115

Step-by-step explanation:

Proportion or those who feel secure, p = 0.45

Sample size, n = 8

Using the binomial distribution formula :

P(x =x) = nCx * p^x * (1 - p)^(n - x)

A.) p(x = 5)

P(x =5) = 8C5 * 0.45^5 * 0.55^3

P(x = 5) = 56 * 0.0184528125 * 0.166375

P(x = 5) = 0.1719248540625

P(x = 5) = 0.172

B.) P(x > 5)

P(x > 5) = P(x = 6) + P(x = 7) + P(x = 8)

P(x > 5) = 0.0703 + 0.0164 + 0.0017

P(x > 5) = 0.0884

C.) P( ≤ 5) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3) + P(x = 4) + P(x = 5)

Using the binomial probability calculator to obtain a direct solution :

P( ≤ 5) = 0.9115

Answer:

A. 3 hours and 51 mins long

Step-by-step explanation:

22-13= 9 min difference

11-3=4 but since there is a 9 min difference it would be 9 mins away from 4 hours so that why is it 3 hours and 51 minutes long

hope this wasnt confusing

36 students in math class

Answer:

36 students in the math class

Step-by-step explanation:

Find the difference between numbers:

Divide the second number by the first number:

36/108 = 1/33

Divide the third number by the second number:

12/36 = 1/3

The difference is 1/3

Multiply the last known number by 1/3 for the next number:

12 x 1/3 = 4

The next term is 4

Answer:

only -2 is in the domain

Step-by-step explanation:

For negative values under the sqrt, there is no real answer, hence

-2x ≥ 0

only for x=-2 this is the case.

The domain represents all the valid input values for x.

Answer: $14160

Step-by-step explanation:

Simple interest would be calculated as:

= PRT/100

where,

P = Principal = $12000

R = Rate = 6%

T = Time = 3 years

Simple interest = ($12000 × 6 × 3)/100

= $216000/100

= $2160

The amount that Tobias owe in all would be:

= $12000 + $2160

= $14160

Step-by-step explanation:

Answer:

$113.90

Step-by-step explanation:

Find the cost of the meal with sales tax:

90 x 0.075 = 6.525

Add that to the original cost of the meal:

90 +  6.525 = 96.525

Find the cost of the tip:

96.525 x 0.18 = 17.3745

Add the tip to the meal price:

96.525 + 17.3745 = 113.8995

There are total 300 pieces of candy.

Adrian gets 1/4 of total

Multiply the total number by 1/4, to find the number Adrian gets:

Darien gets 10% of total.

10% is equal to 10/100 = 1/10. Multiply 300 by 1/10 to get the number Darien gets:
