What is the value of 7x (3 + x/4) when x= −8?
A −280
B −170
C −56
D 280
PLEASE HELP ME

Answers

Answer 1
The answer is -56. For future problems, I highly recommend the calculator app “Desmos”, and writing the equation out in the calculator, and then replacing X values with the number (-8).
Answer 2

Answer:

-56

Step-by-step explanation:

Equation = 7x( 3 + x/4)

f(x) = 7x( 3 + x/4)

f(-8) = 7( -8 )( 3+ -8/4 )

f(-8) = -56 ( 3+ ( - 2 ))

f(-8) = -56( 1 )

f(-8) = -56

What is the Domain and range of y = 2 x - 11 + 2

Answers

Step-by-step explanation:

the domain is the set or range of valid values for x.

the range is the set or range of valid values for y (= f(x)).

if you did not miss anything in your problem statement, then I see a function

y = 2x - 11 + 2

no restrictions are defined.

so, domain and range are both the interval

(-infinity, +infinity).

notice the round brackets, as "infinity" is never a value and cannot be included in an interval.

now, if you missed a division sign and the function looks like

y = 2/x - 11 + 2

then we know, x must never be 0, as a division by 0 is undefined.

so, the domain in that case would be

-infinity < x < 0, 0 < x < +infinity

or short

x <> 0

the range would still be every possible value in

(-infinity, +infinity).

Janice Went to five different stores in the mall, she spent an average of $30 at each store. After visiting just the first four stores she had spent $100, how much was she have spent at the last store based on her overall average?

A.$25
B.$30
C.$50
D.$70

Answers

Based on Janice average, she spent $50 at the last store.

Let a, b, c, d, e represent the money spent on the five stores respectively.

Since she spent an average of $30 at each store, hence:

(a + b + c + d + e) / 5 = 30

(a + b + c + d + e) = 150

She spent $100 on the first four stores, hence:

a + b + c + d = 100

(a + b + c + d + e) = 150

100 + e = 150

e = 50

Hence based on Janice average, she spent $50 at the last store.

The cost to mail a letter is a base charge of $0.42 plus $0.17 for each ounce. Write an expression to represent the cost for mailing a letter that is w ounces. Then find the cost for mailing a letter that is four ounces.

0.17 + 0.42w; $1.85
0.42 + 0.17w; $1.10
0.17 + 0.42w; $2.36
0.42 + 0.17w; $2.36

Answers

the total cost of mailing a letter is expressed by : 0.42 + (0.17w)
the cost of mailing a four ounces letter is $1.10
step by step explanation:
first, you have a fixed cost, independent of any other variable, which is: 0.42.
then you have a cost that is independent on the weight. expressed the ounces, which is: 0.17 per ounce. that means if you have 2 ounces then your cost would be duplicated, becoming 0.34 and so on forth, let’s define the weight as w.
the total cost of mailing a letter equals the base charge or the fixed cost. plus the cost of the number of ounces that our letter weighs.
we can express this statement in a mathematics terms:
0.42 + ( 0.17 * w) = COST

now, we want to know how much it would cost us to mail a letter that weighs 4 ounces. that means we know the value of the “w” in our expression, so we can substitute it and solve the expression:
0.42 + (0.17 * 4 ) = COST
0.42 + 0.68 = COST
1.1 = COST

it would cost us $1.10 to send a 4 ounces letter :)

A bank pays simple interest at the rate of 5% per annum on all deposits. Interest is credited to the account quarterly on March 31st, June 30th , September 30th and December 31st, based on the minimum quarterly balance for that period. If a person opens an account with a deposit of $ 40,000 on January 1st. They then make a withdrawal of $ 3,000 on 10th June. If there were no further transactions (deposits or withdrawals), how much interest will be credited to the account on December 31st. ​

Answers

Balance Jan 1 = $40000
Interest Mar 31 = 40000 x 5% = $2000
Balance Mar 31 = 40000 + 2000 = $42000
Withdraw Jun 10 = $3000
New balance = $39000
Interest Jun 30 = 39000 x 5% = $1950
Balance Jun 30 = 39000 + 1950 = $40950
Interest Sep 30 = 40950 x 5% = $2047.50
Balance Sep 30 = 40950 + 2047.50 = $42997.50
Interest Dec 31 = 42997.50 x 5% = $2149.88 rounding up to nearest cent

La barbería El Caleño, tiene en promedio 120 clientes a la semana a
un costo actual de $6000 por corte de cabello. Se sabe que por cada incremento
de $700 en el precio, la peluquería pierde 10 clientes. ¿Cuál es el precio máximo
que puede cobrarse de modo que los ingresos semanales no sean menores que los
actuales?

Answers

Queremos maximizar el precio de tal forma que los ingresos no disminuyan.

Ese maximo precio es: $14,040.6

Sabemos que actualmente el precio es:

p = $6,000

El número de clientes es:

C = 120

Actualmente los ingresos son el producto de esos dos números, es decir:

ingresos = $6,000*120 = $720,000

Ahora sabemos que por cada incremento de $700 en el precio, el número de clientes decrece en 10.

Entonces podemos escribir el número de clientes como una ecuación lineal.

C(p) = a*p + b

tal que tenemos dos puntos en esa linea:

($6,000, 120)

($6,700, 110)

La pendiente es:

[tex]a = \frac{110 - 120}{\$6,700 - \$6,000} = \frac{-10}{\$ 700}[/tex]

Entonces tenemos:

C(p) = (-10/$700)*p + b

Sabemos que:

C($6,000) = 120 = (-10/$700)*$6,000 + b

                     120 = -85.71 + b

                     120 + 85.71 = b =

Entonces la ecuación lineal es:

C(p) = (-10/$700)*p + 205.71

Los ingresos serán dados por:

ingresos = C(p)*p = (-10/$700)*p^2 + 205.71*p

Y queremos maximizar p de tal forma que esto sea igual a lo que obtuvimos antes:

(-10/$700)*p^2 + 205.71*p = $720,000

Entonces debemos resolver la ecuación cuadratica:

(-10/$700)*p^2 + 205.71*p - $720,000 = 0.

Las soluciones son dadas por la formula de Bhaskara.

[tex]p = \frac{-205.71 \pm \sqrt{(205.71)^2 - 4*(-10/\$ 700)*\$ 720,000} }{2*(-10/\$ 700)} \\\\p = \frac{-205.71 \pm 195.45}{(-20/\$ 700)}[/tex]

La solución de maximo valor es:

p = (-205.71 - 195.45)/(-20/$700) = $14,040.6
