Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So first you have to plug in what you know...
[tex]3x+y>3\\3(\frac{3}{4})+(0)>3\\\frac{9}{4}+0>3\\\frac{9}{4} >3[/tex]
If it's hard to look at it that way you should make it look like this...
[tex]2\frac{1}{4} >3[/tex]
Now when you look at it you can tell that it's false, so [tex](\frac{3}{4},0 )[/tex] is not a solution f this inequality.

Answer:
translate <-6, 0>, reflect over x
Step-by-step explanation:
Point D is at the top in the pre-image and at the bottom in the image, so a vertical reflection is indicated. Only the 1st and 3rd choices show a reflection over the x-axis.
The image is to the left of the pre-image by 6 units, so the translation is in the negative direction. Only the 3rd choice has that.

Answer:
positive infinitynegative infinityStep-by-step explanation:
The function has a positive leading coefficient (1/3) and is of odd degree (3). These conditions mean the sign of the end behavior of the function will match the sign of x.

Step-by-step explanation:
Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5
Una tienda compra pendrive de diferentes
colores al por mayor, para navidad hizo un
pedido extraordinario de 84 memorias rojas, 196 azules y 252 verdes. Para guardar la
mercancía de forma organizada, exigió que
le enviarán las memorias en cajas iguales,
sin mezclar los colores y conteniendo el mayor número posible de memorias.
Answer:
En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.
Step-by-step explanation:
La cantidad de cajas es igual a la cantidad de memorias dividida por la capacidad de una caja. Al indicarse que las memorias serán guardadas en cajas de igual capacidad, sin mezclar los colores y con el mayor número posible de artículos, podemos utilizar el concepto de máximo común divisor, cuyo procedimiento mostramos a continuación:
(i) Realizamos la descomposición factorial de cada número:
Memorias rojas:
[tex]84 = 2\times 2 \times 3\times 7[/tex]
Memorias azules:
[tex]196 = 2\times 2\times 7\times 7[/tex]
Memorias verdes:
[tex]252 = 2\times 2\times 3 \times 3 \times 7[/tex]
(ii) Hallamos los números primos en común que tiene cada colección de memorias:
[tex]S=\{2,2,7\}[/tex]
(iii) Calculamos el máximo común divisor al multiplicar los elementos del conjunto S:
[tex]M.C.D. = 2\times 2\times 7[/tex]
[tex]M.C.D. = 28[/tex]
Esto quiere decir que cada caja debe llevar 28 memorias del mismo color. Finalmente, calculamos la cantidad requerida de cajas para cada memoria.
Memorias rojas:
[tex]n_{R} = \frac{84}{28}[/tex]
[tex]n_{R}= 3[/tex]
Memorias azules:
[tex]n_{A} = \frac{196}{28}[/tex]
[tex]n_{A} = 7[/tex]
Memorias verdes:
[tex]n_{V} = \frac{252}{28}[/tex]
[tex]n_{V} = 9[/tex]
En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.
A cab charges $1.45 for the flat fee and $0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can travel if she has $35 to spend.
answers are:
A. $1.45 + $0.55x ≥ $35; x ≥ 61 miles
B. $1.45 + $0.55x ≤ $35; x ≤ 61 miles
C. $0.55 + $1.45x ≥ $35; x ≥ 23 miles
D. $0.55 + $1.45x ≤ $35; x ≤ 23 miles
9514 1404 393
Answer:
B. $1.45 + $0.55x ≤ $35; x ≤ 61 miles
Step-by-step explanation:
The mileage charge for x miles will be $0.55x, so the total charge will be $1.45+$0.55x. This must be less than or equal to $35 for Ariel to be able to pay for her travel. The appropriate inequality is ...
$1.45 +$0.55x ≤ $35 . . . . . matches choice B
__
Comment on selecting an answer
From a "reasonableness" point of view, any answer choice with "≥ $35" can be eliminated immediately. Further, any answer choice with $1.45x can be eliminated, since the mileage charge is not $1.45, it is $0.55. The leaves only the choice shown above.
what is x ?
what is y ?
Answer:
y = 100° , x = 80°
Step-by-step explanation:
Two angles on a straight line equal 180°. Therefore, 80° + y = 180°. This means y = 100°.
80° and x are alternate exterior angles. Using that property, we know those angles are congruent. This means x is also 80°.
Jessie paid $43.75 for 5 movie tickets. Each ticket cost the same amount. What was the cost of each movie ticket in dollars and cents?
Answer:
$8.75
Step-by-step explanation:
Divide $43.75 by 5 to get the cost of ONE movie ticket like so:
$43.75 / 5 movie tickets = $8.75 per ticket.
Therefore, ONE ticket costs $8.75.

Step-by-step explanation:
Answer:
my guess is irrational
Step-by-step explanation:
A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).

(-90) + (-20) + 100 =
A-210
B) 10
C) -10
D) 210
Answer:
C.
Step-by-step explanation:
(-90) + (-20) + 100 = -10
Hope I Helped! :)
Answer:
The solution is C. -10
Step-by-step explanation:
Before entering the solution, remember the formula first!
Addition
• (-) + (-) = (-)
• (+) + (+) = (+)
Subtraction
• (+) - (+) = can (-) and (+)
• (+) - (-) = (+)
Multiplication
• (-) x (-) = (+)
• (+) x (-) = (-)
Division
• (-) : (-) = (+)
• (+) : (-) = (-)
Solution:
(-90) + (-20) + 100
= -90 - 20 + 100
= -110 + 100
= -10 (the minus number is greater than the positive, then the result is minus)
