Please answer the following question.
For dinner, Javier will choose one of the four fish options and one of the three side dishes.

Evaluate the expression is -10.

You must replace each variable with a number and carry out the arithmetic procedures to evaluate an algebraic expression. As 6 + 6 = 12, the variable x in the preceding example is equal to 6. We can replace our variables with their values if we know what they are, then evaluate the expression after doing so.

The division can be done as follows when assessing the phrase 8 4:

−8 ÷ −4 = 2

The expression is thus reduced to:

2 - 12

12 is subtracted from 2 to yield:

-10

Thus, -10 is the correct response.

Answer:

La fórmula para calcular el balance (en dólares) de una inversión con una

A = P(1 + r/n)^(nt)

Donde:

A es el balance total después de t años

P es el depósito inicial

r es la tasa de interés anual expresada como decimal (5% = 0.05)

n es la frecuencia de capitalización por año (en este caso, 4 para compuestos trimestrales)

t es el tiempo en años

Sustituyendo los valores dados, la función que representa el balance después de t años es:

A(t) = 5000(1 + 0,05/4

b. Para encontrar el balance actual, podemos simplemente evaluar la función A en t = 0, lo que nos da:

A(0) = 5000(1 + 0,05/4

Por lo tanto, el balance actual de la cuenta es de $5000.

c. Supongamos que el costo de la matrícula y los gastos de su primer año en la universidad suman $20,000. Para determinar si la inversión cubrirá el costo, podemos evaluar la función A en t = 12 (es decir, después de 12 años desde el depósito inicial) y compararla con el costo de la matrícula y los gastos.

A(12) = 5000(1 + 0.05/4)^(4(12)) = $10,768.49

Como el balance de la cuenta después de 12 años es menor que el costo de la matrícula y los gastos, se necesitará más dinero para cubrir el costo del primer año de universidad. La cantidad adicional requerida será:

$20,000 - $10,768.49 = $9,231.51

Por lo tanto, se necesitarán $9,231.51 adicionales para cubrir el costo del primer año de universidad.

Option C. No, because the 100 adults were selected without replacement, the selections are dependent.

The binomial probability formula assumes that the trials are independent, meaning that the probability of success or failure for each trial remains the same regardless of the outcomes of previous trials. However, in this case, the 100 adults were selected without replacement, so the probability of being left-handed for each selection depends on the outcomes of previous selections. Therefore, the binomial probability formula cannot be used to find the probability in this situation.

Answer: Decay

Step-by-step explanation:

Answer:

This pair of equations is solvable by substitution, as I can easily substitute for y because it is already isolated in both equations. After substituting for y, I will solve the equations to get the value of x and then substitute that x-value into the simpler of the two equations, y = x - 1. Once I have both the x-value and y-value, they will be put into a point (x,y).

y = 3x + 3

y = x - 1

x - 1 = 3x + 3

    x = 3x + 4

  -2x = 4

    x = -2

     y = x - 1

     y = ( -2 ) - 1

     y = -3

The final answer to the pair of inequalities is ( -2,-3 )

Step-by-step explanation:

y = 3x + 3

y = x - 1

"substitution" means we are defining one variable by an expression of the other variable and use this identity in one of the original equations.

in our case here the main work was already done (even twice) : y is defined as expressions in x.

we even have the luxury to pick which one and then to use it in the other.

it does not matter which one you pick, it will lead to the same result.

so, let's use the identity of equation 1 in equation 2 : we replace every occurrence of y by the defined identity

y = x - 1

turns into

3x + 3 = x - 1

now we subtract x from both sides

3x + 3 - x = x - 1 - x

2x + 3 = -1

now we subtract 3 from both sides

2x + 3 - 3 = -1 - 3

2x = -4

and finally we divide both sides by 2

2x/2 = -4/2

x = -2

this result we use now in one of the original equations to get y :

e.g.

y = x - 1

y = -2 - 1 = -3

so, the solution is (-2, -3)

The length along a line or line segment between two points on the line or line segment.

Distance=√(x₂-x₁)²+(y₂-y₁)²

The distance from your home to the school is 2 miles south, which means the y-coordinate of the school is -2.

The mall is located 5 miles west of the school, which means the x-coordinate of the mall is -5.

So, we have two points on the coordinate plane: your home at (0, 0) and the mall at (-5, -2).

The distance between them can be found using the distance formula:

Distance=√(x₂-x₁)²+(y₂-y₁)²

Like terms, functions may be combined by addition, subtraction, multiplication or division.

Example 1. Given f ( x ) = 2x + 1 and g ( x ) = x2

+ 2x – 1 find ( f + g ) ( x ) and

( f + g ) ( 2 )

Solution

Step 1. Find ( f + g ) ( x )

Since ( f + g ) ( x ) = f ( x ) + g ( x ) then;

( f + g ) ( x ) = ( 2x + 1 ) + (x2

+ 2x – 1 )

= 2x + 1 + x2

+ 2x – 1

= x

2

+ 4x

Step 2. Find ( f + g ) ( 2 )

To find the solution for ( f + g ) ( 2 ), evaluate the solution above for 2.

Since ( f + g ) ( x ) = x2

+ 4x then;

( f + g ) ( 2 ) = 22

+ 4(2)

= 4 + 8

= 12

Example 2. Given f ( x ) = 2x – 5 and g ( x ) = 1 – x find ( f – g ) ( x ) and ( f – g ) ( 2 ).

Solution

Step 1. Find ( f – g ) ( x ).

( f – g ) ( x ) = f ( x ) – g ( x )

= ( 2x – 5 ) – ( 1 – x )

= 2x – 5 – 1 + x

= 3x – 6

Step 2. Find ( f – g ) ( 2 ).

( f – g ) ( x ) = 3x – 6

( f – g ) ( 2 ) = 3 (2) – 6

= 6 – 6

= 0

Step-by-step explanation:

(f • g)(x) = f(g(x))

         = f(x-1)

         = 2(x-1)^2

Therefore, (f • g)(3) = 2(2)^2 = 8

Answer:

(f • g)(x) = 2(x-1)^2 and (f • g)(3) = 8.

Step-by-step explanation:

We have, to substitute g(x) into f(x) wherever we see x in f(x),to find (f • g)(x).

Which will give,

(f • g)(x) = f(g(x))

             = f(x-1)

             = 2(x-1)^2

We have to put x = 3 to evaluate this expression,

(f • g)(3) = 2(3-1)^2

             = 2(2)^2

             = 8

Therefore,

(f • g)(x) = 2(x-1)^2 and (f • g)(3) = 8.
