Answer:

y-determinant = 2

Step-by-step explanation:

Given the following system of equation:

Let's represent it using a matrix:

[tex]\left[\begin{array}{ccc}1&2\\1&-3\end{array}\right] = \left[\begin{array}{ccc}5\\7\end{array}\right][/tex]

The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:

[tex]\left[\begin{array}{ccc}1&5\\1&7\end{array}\right] [/tex]

y-determinant = (1)(7) - (5)(1) = 2.

Therefore, the y-determinant = 2

Pulling out like terms :

2.1     Pull out like factors :

  4x + 2y  =   2 • (2x + y)

Final result :

 4 • (2x + y)

Step-by-step explanation:

The expression 2(4x+2y) is equivalent to 8x + 4y.

The expression 2(4x + 2y) can be simplified using the distributive property, also known as the distributive law or the distributive property of multiplication over addition.

This property allows you to distribute the factor outside the parentheses to each term inside the parentheses. Here are some equivalent expressions:

Distributing the 2:

2(4x + 2y) = 2 * 4x + 2 * 2y = 8x + 4y

Using the distributive property in reverse:

2(4x + 2y) = 4x(2) + 2y(2) = 8x + 4y

Factoring out a common factor:

2(4x + 2y) = 2 * (2 * 2x + 2 * y) = 2 * 2(2x + y) = 4(2x + y)

Answer:

The correct answer is 49.

Step-by-step explanation:

We are given the following expression and we are supposed to evaluate it:

– (31 + 2) + 72 – (–5) 2

Solving the terms inside the brackets first, following the order of operations to solve a mathematical expression to get:

= - (33) + 72 - (-5) 2

Then we will do the multiplications to get:

Answer:

They will meet at 3836 meters

Step-by-step explanation:

Maya is at 7832 meters

Juan is at -160 meters  ( below sea level)

If they are meeting at the midpoint, we add them together and divide by 2

Midpoint = (7832 + -160)/2

               = (7672)/2

               =3836 m

Answer:

The midpoint elevation will be 3,836 meters.

Step-by-step explanation:

Maya's elevation of 7832 can be represented by the positive integer +7832 since she is above sea level.  Sea level would represent 0 on our number line.  However, Juan is below sea level, so we can represent his distance at -160.  When we add these two integers together +7832 + (-160) = 7672 meters above sea level.  Since Maya and Juan are going to meet at the midpoint, we would divide our overall distance (7672) by two to get 3836 meters.

The caloric content of the pan pizza is 1110 calories and the caloric content of the beef burrito is 1230 calories.

Let's assign variables to the caloric content of the items. Let x represent the caloric content of the pan pizza and y represent the caloric content of the beef burrito. We can form two equations based on the given information:

x + 2y = 3570

2x + y = 3450

To solve this system of equations, we can use either substitution or elimination method. Let's use substitution method:

y = 3450 - 2x

x + 2(3450 - 2x) = 3570

x + 6900 - 4x = 3570

-3x = -3330

x = 1110

2(1110) + y = 3450

2220 + y = 3450

y = 1230

Therefore, the caloric content of the pan pizza is 1110 calories and the caloric content of the beef burrito is 1230 calories.

Answer:

The total pennies in Russell's collection dated after 2000 is 800

Step-by-step explanation:

Given

Total Pennies: 1,200

Pennies before 1980: 25%

Pennies between 1980 and 2000: 35%

Required

Number of pennies in Russell’s collection are dated after 2000

Let P1 represent pennies dated before 1980

Let P2 represent pennies dated between 1980 and 2000

Let P3 represent pennies dated after 2000

To calculate the number of pennies dated after 2,000. you have to understand that his total collection of pennies is 100%

This means that

P1 + P2 + P3 = 100%

Where P1 = 25% and P2 = 35%.

So, we're solving for P3

By substituting, P1 = 25% and P2 = 35%, we have

25% + 35% + P3 = 100%

60% + P3 = 100%

Make P3 the subject of formula

P3 = 100% - 60%

P3 = 40%

The quantity of pennies dated after 2,000 is then calculated by P3 * Total.

i.e. 40% * 2000

= 0.4 * 2000

= 800

Hence, the total pennies in Russell's collection dated after 2000 is 800

Answer: u = -4w + 9

Step-by-step explanation:

u - 5 = -4(w - 1)

u - 5 = -4w + 4

  +5           +5  

u         = -4w + 9

The proper formula to solve the equation u - 5 = -4(w - 1) for w is w = (u + 9) / 4, after rearranging and simplifying the terms of the equation.

The question involves solving a linear equation with variables u and w. Initially, we have the equation u - 5 = -4(w - 1). To solve for w, we need to isolate w on one side of the equation. A statement in the information provided seems to mistakenly give the result of w, which probably arises from a typo or error, stating w = -40 - 5. However, this is incorrect given the initial equation.

Let's start by expanding the right side of the initial equation:

And then rearranging to solve for w:

From this process, we see that the correct formula to isolate and solve for w is w = (u + 9) / 4.

Answer:

18.1 million

Step-by-step explanation:

12.1 - 4.9 = 7.2 million increase in 6 years

7.2 / 6 = increase of 1.2 million a year

1.2 x 5 years = 6 million

12.1 million + 6 million = sales of 18.1 million in 2001

Based on linear growth from 1990 to 1996, ABC Electronics can expect total sales of approximately $18.1 million in 2001.

To predict sales for ABC Electronics in 2001 based on a linear growth pattern from 1990 to 1996, we first calculate the annual increase in sales over that period. In 1990, sales were $4.9 million and in 1996, sales were $12.1 million. This is an increase of $12.1 million - $4.9 million = $7.2 million over 6 years, which gives us an annual increase of $7.2 million / 6 years = $1.2 million per year.

Since we're assuming linear growth, we can extend this annual increase to predict sales for subsequent years. From 1996 to 2001 is 5 years, so we calculate the expected sales for 2001 by adding 5 times the annual increase to the 1996 sales figures: $12.1 million + (5 × $1.2 million) = $12.1 million + $6.0 million = $18.1 million.

Therefore, we can expect ABC Electronics to have total sales of approximately $18.1 million in the year 2001 if the linear growth trend continues.

Answer:

[tex]y = 140000(1.04)^{x}[/tex]; 262 000

Step-by-step explanation:

The general formula for an exponential function is

[tex]y = a(b)^{x}[/tex]

a = 140 000; b = 1.04; x = 16

[tex]y = 140000(1.04)^{x}[/tex]

y = 140 000(1.04)¹⁶

y = 140 000 × 1.873

y = 262 000

The graph below shows the population growth over time.

Final answer:

An exponential function to model the population growth is P(t) = P_0 * e^{rt}, where the initial population P_0 is 140,000, the rate of growth r is 0.04, and the time t is 16 years. The population after 16 years is calculated by P(16) = 140,000 * e^{0.64}.

Explanation:

To model the population growth, we can use the formula for exponential growth which is P(t) = P_0 e^{rt}, where:

P(t) is the future population after time t,

P_0 is the initial population size,

e is the base of natural logarithms (approximately equal to 2.71828),

r is the rate of growth (expressed as a decimal), and

t is the time in years.

In the given situation, the initial population P_0 is 140,000, the growth rate r is 4% per year which is 0.04 when expressed as a decimal, and the time period t is 16 years. Plugging these values into the formula:

P(16) = 140,000 * e^{0.04 * 16}

To calculate the future population after 16 years, solve the equation:

P(16) = 140,000 * e^{0.64}

Using a calculator to compute e^{0.64}, and then multiplying by 140,000, we obtain the future population.

Answer:

Final answer:

Jim can rent the car for a maximum of 4 whole days with his budget of $115, as the inequality 21d + 0.10(250) <= 115 reveals that he doesn't have enough funds to cover the fifth day.

Explanation:

To determine the maximum number of days Jim can rent a car, we can set up an inequality. The cost per day to rent the car is $21.00, and he will be charged $0.10 for every mile he drives. Jim will travel 250 miles in total. Jim has a budget of $115.00 to spend.

Let d represent the number of days Jim can rent the car for. The inequality would be:

21d + 0.10(250) ≤ 115

To solve for d, you would perform the following steps:

Solving the inequality:

21d ≤ 90

d ≤ 90 / 21

d ≤ 4.2857

Since Jim can only rent the car for a whole number of days, the maximum number of days he can rent the car is 4 days.

Therefore, Jim's belief that he can rent the car for a maximum of 5 whole days is incorrect because he does not have sufficient funds for the fifth day.
