Linear equations are equations that have constant slopes

The linear equation that represents the table is (a) y = 7x +4

How to determine the linear equation

Start by calculating the slope (m) using:

So, we have:

Simplify

The equation is then calculated as:

So, we have:

Open the brackets

Hence, the linear equation that represents the table is (a) y = 7x +4

Answer:

w = 1

Step-by-step explanation:

y = [tex]x^{4}[/tex] + 4w²x³ - 11wx² - 30wx

if x = 3 , then y = 0

[tex]3^{4}[/tex] + 4w²( 3 )³ - 11w( 3 )² - 30w( 3 ) = 0

108 w² - 99 w - 90w + 81 = 0 ........ (1)

(1) ÷ 9

12w² - 21w + 9 = 0 ⇒ [tex]w_{1}[/tex] = 1 and [tex]w_{2}[/tex] = [tex]\frac{3}{4}[/tex]

"1" the value for w that match the graph.

w = 1

Answer:

Option (A)

Step-by-step explanation:

Correct proof to prove the vertical angles are congruent :

1). Linear pairs of angles are supplementary.

   m∠2 + m∠3 = m∠3 + m∠4

2). By subtracting m∠3 from both the sides of the above equation.

3). By definition of congruent angles, ∠2 ≅ ∠4. This will show that ∠2 and ∠4 are vertical angles.

Therefore, Option (A) is incorrect in which Angelina showed that linear pairs of angles are complementary.

Answer:

x = 1 over 4 ( which is also 0.25 and x=2^-2)

Step-by-step explanation:

4^-3x = 4^x-1

-3x = x - 1

-3x - x = -1

-4x = -1

divide both sides

x = 1 over 4

Step-by-step explanation:

The tip is 20% of what he paid for lunch. Hence

tip = 20% of 50.50 = (20/100)*50.50 = 101/100 = $10.10

Total spent

50.50 + 10.10 = $60.60

So hence, Tim spent $60.60 for his lunch.

Answer: 6042.23

Step-by-step explanation:

P0=d(1−(1+rk)−Nk)(rk).

We have P0=$1,200,000,r=0.0195,k=12,N=20, so substituting in the numbers into the formula gives

$1,200,000=d(1−(1+0.019512)−20⋅12)(0.019512),

that is,

$1,200,000=198.602327d⟹d=

The total interest payable is $4,68,000.

Given,

An executive wishes to take out a $1,200,000 mortgage.

The yearly interest rate on the loan is 1.95% and the loan is for 20 years.

Payments will be made monthly.

Calculate the total interest payable.

Round your answer to the nearest thousand dollars.

It is given by:

SI = (P x R x T) / 100

P = principal amount

R = rate

T = time

We have,

P = $1,200,000

R = 1.95%

T = 20 years

SI = (P x R x T) / 100

SI = (1200000 x 1.95 x 20) / 100

SI = (1,200,000 x 195 x 20) / 100 x 100

SI = 120 x 195 x 20

SI = $4,68,000

Thus the total interest payable is $4,68,000.

Answer:

8r + 9p

Step-by-step explanation:

Combine like terms. Like terms are terms with the same variables as well as the same amount of said variable.

In this case, combine 12p with -3p

8r + 12p - 3p

8r + (12p - 3p)

8r + 9p

8r + 9p is your answer.

~

While adding such algebraic expressions, we combine the like terms which contains the same variables infact same degree of variables.

Given expression:

Here 12p and 3p are like terms because they are having same variable that is p. So, we can compute any operation like hear it's subtraction.

➝ 8r + (12p - 3p)

➝ 8r + 9p

Now no more like terms are there, So the final answer is 8r + 9p. And we are done!

Answer:0.09

Step-by-step explanation:

Answer:

Before solving these, we must know;

· A 90° angle forms a right angle.

· A 180° angle forms a straight angle.

· Any angle greater than a 90° angle is considered an obtuse angle (x > 90 = obtuse).

· Any angle less than a 90° angle is considered an acute angle (x < 90 = acute).

Now just eyeing these, I can tell that;

1. Is acute, because it looks like it is smaller than a 90° angle(right angle).

2. Is straight, because it looks fairly like a straight line(which measures 180°).

3. Is obtuse, because it looks greater than a 90° angle(right angle).

4. Is right, because it looks exactly like a 90° angle(right angle).

    Huckabee                        0.19                                     118

    Guiliani                              0.12                                    75

    Undecided votes                   0.28                                 174

Step-by-step explanation:

From the question we are told that

   The  number of voters is  n  =  621

   The  voter  election aspirants  and their relative frequency are

Romney , 0.21

Huckabee , 0.19

Guiliani  ,  0.12

John McCain ,0.10

 Ron Paul , 0.04

Fred Thompson 0.04,

Duncan Hunter 0.01

Tom Tancredo 0.01

Undecided votes 0.28

This undecided vote is used to represent votes that did not count and it is obtained by subtracting the other relative frequencies  from  1 (i.e 100%)

Generally the frequency is mathematically represented as

 Romney ,  621 *  0.21  =  130      

Huckabee ,  621 *  0.19    =  118

Guiliani  ,   621 * 0.12 =  75

John McCain      621 * 0.10 = 62

 Ron Paul , 621 * 0.04  =  25

Fred Thompson 621 * 0.04 =  25

Duncan Hunter 621 *  0.01  = 6

Tom Tancredo 621 * 0.01 =  6

Undecided votes 621 * 0.28 =  174

So the table is  

    Voters                 Relative Frequency                Frequency

   Romney                            0.21                                     130      

    Huckabee                        0.19                                     118

       Ron Paul                         0.04                                    25

 Fred Thompson                    0.04                                     25

  Duncan Hunter                      0.01                                      6

Resolviendo el sistema de ecuaciones veremos que:

Aqui tenemos el sistema de ecuaciones:

Niña + niño = 51kg

Niño + perro = 46 kg

Niña + perro = 41kg

Para resolver esto, lo primero que debemos hacer es aislar una variable en una de las ecuaciones, por ejemplo, podriamos aislar "perro" en la tercera:

perro = 41kg - niña

Ahora reemplazamos eso en la segunda para obtener:

niño + (41kg - niña) = 46kg

niño - niña = 46kg - 41kg = 5kg

niño = niña + 5kg

Ahora logramos obtener la variable "niño" en terminos de la variable "niña". Podemos reemplazar esto en la primera ecuacion del sistema.

niña + niño = 51kg

niña + (niña + 5kg) = 51kg

2*niña = 51kg - 5kg = 46kg

niña = 46kg/2 = 23kg.

Ahora que sabemos esto, usamos las otras ecuaciones para encontrar el peso del niño y el perro:

niño = niña + 5kg = 23kg + 5kg = 28kg

perro = 41kg - niña = 41kg - 23kg = 18kg.

Step-by-step explanation:

Get the slope of the line between the two points. As usual, [tex]m= \frac{\Delta y}{\Delta x}= \frac{8-(-18)}{4-(-2)}=\frac{8+18}{4+2}=\frac{26}{6}=\frac{13}3[/tex]

Answer:

Part A: its linear

Part B: it is a function

Step-by-step explanation:

The function shown on the graph has the same rate of change, but a higher starting point

Fine the diagram needed attached.

The rate of change of the line is the slope of the line. The standard equation of a line is expressed as y = mx + b;

Given the equation y = 5x + 5, the rate of change of the expression is 5.

For the given graph, the slope of the graph is expressed as:

(2, 4) and  (0, -6)

m = -6-4/0-2

m =-10/-2

m = 5

Given function:

s(d) = 20d

where:

To determine the composite function that represents how many palm trees Carlos can expect to grow over a certain number of days, simply substitute s = 20d into t(s) = 3s + 20:

⇒ t(d) = 3(20d) + 20

⇒ t(d) = 60d + 20

where t(d) is the number of palm trees grown, and d is the number of days.

Well supplementary means that both the angles add up to 180

We know that the measure of angle 3 is 13 degrees.
The measure of angle 4 is unknown
And the total of angles 3 and 4 are 180.

x= 167

Measure of angle 4 is 167
