The ordered pair that is a solution of the system of inequalities:

4x + 2y > 8

x - y ≥ 2

is (7, 2)

Here we have the following system of inequalities:

4x + 2y > 8

x - y ≥ 2

The points (x, y) are solutions only if make both inequalities true. For example let's use the first pair (2, 4)

Replacing that in the inequalities we get:

4*2 + 2*4 > 8

2 - 4 ≥ 2

Simplify the left side:

16 > 8

-2  ≥ 2

The second inequality is false, so (2, 4) is not a solution.

The correct option is the second one, (7, 2), evaluating the inequalities we get:

4*7 + 2*2 = (32) > 8

7 - 2 = 5 ≥ 2

You can see that both are true.

The system of inequalities is

x + y ≥ 14

5x + 2.5y ≤ 60

Given, that Yaritza and her children went into a restaurant that sells hamburgers for $5 each and tacos for $2.50 each.

Yaritza has $60 to spend and must buy at least 14 hamburgers and tacos altogether.

As, x represents the number of hamburgers purchased and y represents the number of tacos purchased

Now, according to the question

x + y ≥ 14

as, she must buy at least 14 hamburgers and tacos altogether.

Now, 5x + 2.5y ≤ 60

as, she has $60 to spend.

So, we have two inequalities

x + y ≥ 14

5x + 2.5y ≤ 60

Hence, the system of inequalities for the given problem is

x + y ≥ 14

Answer:

12100

Step-by-step explanation:

If the number B of federally insured banks could be approximated by B ( t ) = − 329.4 t + 13747 from 1985 to 2007 where t = 0 correspond to year 1985

In order to determine the amount of federally insured banks that were there in 1990, we will first calculate the year range from initial time 1985 till 1990

The amount of time during this period is 5years. Substituting t = 5 into the modeled equation will give;

B ( t ) = − 329.4 t + 13747

B(5) = -329.4(5) + 13747

B(5) = -1647+13747

B(5) = 12100

This shows that there will be 12100 federally insured banks are there in the year 1990.

A power outside the bracket should multiply with the inner powers not add, so the first part should be

(3 x^2 y^5)^4

= 3^4 x^(2*4) y^(5*4)

Then you have

The powers that equal can be taken away to give

The probability of selecting 2 red marbles in a row is 1/12.

A bag contains 6 blue marbles, 5 red marbles, 3 green marbles, and 2 yellow marbles. Two marbles are removed from the bag one at a time without being replaced. We need to find the probability of selecting 2 red marbles in a row. Let the probability be represented by the variable "P".

The probability that the first selected marble will be red is given below :

P1 = 5/(6 + 5 + 3 + 2) = 5/16

The probability that the second selected marble will be red is given below :

P2 = 4/(6 + 4 + 3 + 2) = 4/15

The probability that both of the selected marbles will be red is given below :

P = P1*P2 = (5/16)*(4/15) = 1/12.

The answer, Arianna's battery, as a percentage, 3.75t hours after Arianna left her house.

What is percentage?

A percentage that represents a tenth of a quantity. One percent, denoted by the symbol 1%, is equal to one-hundredth of something; hence, 100 percent denotes the full thing, and 200 percent designates twice the amount specified. A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The % sign is used to denote it.

The initial charge of Arianna's phone = 45%

now the charge remaining in Arianna's battery = 15%

If after 4 hours of leaving her house, the battery had 15% remaining battery life, then the battery is discharging at the rate of ( 15% / 4 hours)

=3.75% per hour.

Thus, the charge remaining in Arianna's battery after she left her house will be, B = 3.75t

The hydrogen atoms are on the reactant side in the reaction is 2 atoms.

Reaction is defined as when atoms' chemical bonds are created or ruptured. The substances that start a chemical reaction are known as reactants, and the compounds that are produced as a result of the reaction are known as products. Now that the chemicals had been combined, bonds would be rearranged, resulting in the production of a new product.

We are aware that one of the requirements for formulating a balanced chemical reaction equation is that the quantity of each element's atoms on the reactant side must match the quantity of that element's atoms on the products side. By performing an atom count, we may determine the number of hydrogen atoms present on the reactants side of the reaction when we examine the reaction as it is proved to be balanced.

Thus, the hydrogen atoms are on the reactant side in the reaction is 2 atoms.

When  [tex]x^3[/tex]+4x-24 is divided by x-2 then the remainder is -8.

What is remainder theorem?

 Remainder Theorem is a method for dividing polynomials according to Euclidean geometry. This theorem states that when a polynomial P(x) is divided by a factor (x - a), which isn't really an element of the polynomial, a smaller polynomial is produced along with a remainder. The remainder theorem asserts that when a polynomial p(x) is divided by (x - a), the remainder equals f. (a). Using Euclid's Division Lemma, this may be demonstrated. To put it another way, p(x) = q(x) (x - a) + r if q(x) is the quotient and 'r' is the remainder.

Here the given [tex]x^3[/tex]+4x-24 and x-2

When a function f(x) is divided by x+a, then the remainder is given by f(−a):

So, in this case remainder will be f(2) .

=> f(x)= [tex]x^3[/tex]+4x-24

put x=2 then

=> f(2)= [tex]2^3[/tex]+4(2)-24

=> f(2) =8+8-24

=> f(2) = 16-24 =-8

Hence the remainder is -8.

Linear equations are mathematical equations of the type y = mx + b, with   and x and y being variables. These equations represent a straight line on a graph and are referred to be "linear" since the maximum power of the variable is 1. For example, the equation y = 2x + 3 is a linear equation since the maximum power of the variable x is 1. Linear equations are useful for representing a broad range of real-world events, such as the link between the distance an object travels and the time it takes to traverse that distance. They are a common tool in many disciplines, including physics, engineering, and economics. They are also quite simple to answer.

The give away cost is calculated using the formula

give away cost = number of basket × price

give away cost = 10 × 60 = $600.

the direct product cost can be calculated using the formula

direct product cost = Number of basket x Price x (1-margin%)

direct product cost = 10 × 60 × (1-50%)
