Answer:

x= -8 , y = 5

x= 25/4 , y = 1/4

Step-by-step explanation:

substitute first eqn into the second eqn:

(7 - 3y)^2 -y^2 = 39

49 - 42y + 9y^2 - y^2 = 39

8y^2 - 42y +10 =0

4y^2 - 21y + 5 = 0

(4y-1) (y-5) = 0

y= 1/4 , 5

when y=1/4

x = 7- 3/4

=25/4

when y= 5

x = 7- 15

= -8

The required solution of the given simultaneous equations are x = -8, 25/4 and y = 5, 1/4.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
x = 7 – 3y - - - - -(1)
x² - y² = 39 - - - - (2)

Put x from equation 1 in equation 2

(7 - 3y)² -y² = 39

49 - 42y + 9y² - y² = 39

8y² - 42y +10 =0

4y² - 21y + 5 = 0

(4y-1) (y-5) = 0

y= 1/4 , 5

Substitute this values in the equation 1,
x = -8 and 25/4

The total cost price, including tax and tip, will be $30.96.

An expression expressed as a percentage of 100 is referred to as a percentage. The percent symbol, "%," is widely used to denote it even if the abbreviations "pct," "pct," and rarely "pc" are also employed. A% has no dimensions and no corresponding unit of measurement.

Given that: Sara bought a $24 meal in a town with a 9% sales tax. she tips 20% on the bill, and then adds the sales tax

To figure out the tip, you need to find 20% of $24

0.2×24=4.8

You should leave $4.8 for the tip if you want to leave him exactly 20%.

To figure the tax, you need to find 9% of $24

0.09×24=2.16

Next, add them up:

24+4.8+2.16=30.96

The total cost price, including tax and tip, will be $30.96.

The domain of a function is the set of all possible input values (x-values) for which the function is defined and produces a valid output (y-value).

In this case, the function has a fraction with a square root in the denominator, so the domain is all real numbers except for those values of x that would make the denominator equal to zero.

The denominator of the fraction is √(x^2 - 4x + 5), which is equal to zero when x^2 - 4x + 5 = 0. This is a quadratic equation that can be solved using the quadratic formula, which gives us two solutions: x = (4 ± √(4^2 - 4(1)(5))) / (2 * 1) = (4 ± √(-16)) / 2 = (4 ± 4i) / 2

Since the square root of a negative number is not a real number, the solutions are not real numbers. This means that the denominator is not equal to zero when x = 4 ± 4i. Therefore, the domain of the function is all real numbers except x = 4, which is the only excluded value. So, the domain of the function is (-∞, 4) U (4, ∞).

Answer:

B.

Step-by-step explanation:

The wildflowers in this population, the white allele is present in about 30% of the individuals, while the red allele is present in about 70% of the individuals.

The frequency of the white allele (CW) in the population can be determined by subtracting the frequency of the red allele (CR) from 1, since the frequencies of all alleles in a population must add up to 1.

So, the frequency of the white allele (CW) can be calculated as follows:

CW = 1 - CR

Given that the frequency of the red allele (CR) is p = 0.7, we can substitute this value into the equation:

CW = 1 - 0.7

  = 0.3

Therefore, the frequency of the white allele (CW) in this population is 0.3.

In genetic terms, alleles are alternative forms of a gene, and the frequencies of different alleles within a population can be used to study genetic variations. In this case, we are considering a population of wildflowers and examining the frequencies of the red allele (CR) and white allele (CW).

The total frequency of alleles in a population is always 1 since each individual carries two alleles (one from each parent). Therefore, the frequency of the white allele can be obtained by subtracting the frequency of the red allele (0.7 or 70%) from 1. This is because the sum of the frequencies of all alleles must equal 1.

By performing the calculation, we find that the frequency of the white allele in this population is 0.3 or 30%.

This means that among the wildflowers in this population, the white allele is present in about 30% of the individuals, while the red allele is present in about 70% of the individuals.

It should take approximately 1.98 hours, or around 1 hour and 59 minutes, to cook a 5.17 pound beef rib roast based on the recommended guideline of 23 minutes per pound at a 325°F oven setting.

To calculate the cooking time for a 5.17 pound roast, we can use the recommended guideline of 23 minutes per pound. First, we need to convert the weight from pounds to minutes, and then convert minutes to hours.

Cooking time in minutes = 5.17 pounds * 23 minutes/pound

Cooking time in minutes = 118.91 minutes

To convert minutes to hours, we divide the total minutes by 60:

Cooking time in hours = 118.91 minutes / 60

Cooking time in hours ≈ 1.98 hours

Therefore, it should take approximately 1.98 hours to cook a 5.17 pound beef rib roast based on the recommended guideline of 23 minutes per pound at a 325°F oven setting.

She is incorrect when she said that her rate increased each hour from 8 to 12 to 16 miles per hour. Her jogging rate was actually a steady 5 miles per hour.

You asked if Christy is correct when she said that her rate increased each hour, from 8 to 12 to 16 miles per hour. Let's analyze the data given in the table and see if she's right.

The table shows the distance Christy jogged and the corresponding time:
- 10 miles in 2 hours
- 15 miles in 3 hours
- 20 miles in 4 hours

To find her jogging rate for each time period, we need to divide the distance by the time.

1. For the first 2 hours:
Jogging rate = distance / time = 10 miles / 2 hours = 5 miles per hour

2. For the first 3 hours:
Jogging rate = distance / time = 15 miles / 3 hours = 5 miles per hour

3. For the first 4 hours:
Jogging rate = distance / time = 20 miles / 4 hours = 5 miles per hour

Christy's jogging rate remained constant at 5 miles per hour throughout her run. Therefore, she is incorrect when she said that her rate increased each hour from 8 to 12 to 16 miles per hour. Her jogging rate was actually a steady 5 miles per hour.

Step-by-step explanation:

In the top right table, every x value has only one y value.

The product that will give a negative answer is: −3 × 4 × (−2) × (−7) = -168.

The rule when multiplying two negative numbers is that, the negative signs will cancel each other. That is, minus multiplied by minus will give as plus.

For example, -a × -b = ab

Also, "plus" multiplied by "minus" will also give as "minus. For example:

-a × b = -ab.

Using the above rule, let's find the product of the following:

−3 × 5 × (−6) × 4 = -15 × (-24)

−3 × 5 × (−6) × 4 = 360 [minus × minus = plus]

−7 × (−3) × (−9) × 0 = 0 [anything multiplied by 0 must result to 0]

−4 × (−6) × (−3) × (−5)

= 24 × 15

−4 × (−6) × (−3) × (−5)  = 360

−3 × 4 × (−2) × (−7)

= -12 × 14

−3 × 4 × (−2) × (−7) = -168

Answer:

3 hamburger packs

5 hot dog packs

Step-by-step explanation:

Knowing that:

Gary buy ⇒ 8 packages for a total of $28.52

A package of hot dogs costs $2.29 and a package of hamburgers costs $5.69.

Solving:

Let the Hotdogs = HD

Let the Hamburgers = HB

HD + HB = 8

2.29HB + 5.69HB = 28.52

Hotdogs (HD) = 2.29

Hamburgers (HB) = 5.69

Total ( 8) = 28.52

Since we now know that

Hotdogs (HD) = 2.29

Hamburgers (HB) = 5.69

Thus,

2.29x5 = 11.45

5.69 x 3=17.07

17.07 + 11.45 = 28.52

Thus, gray buy

Confounding variables can affect the relationship between caffeine consumption and heart disease in a correlational study of police officers. Controlling for these variables is necessary to accurately assess the relationship.

The fact that the officers in the study could not be randomly assigned to high and low caffeine groups suggests that the results of the study may be due to confounding variables. A confounding variable is a third variable that is correlated with both the independent variable (in this case, caffeine consumption) and the dependent variable (in this case, heart disease). If a confounding variable is present, it can make it difficult to determine the true relationship between the independent and dependent variables.

For example, if the officers who consume more caffeine also have other unhealthy habits (such as smoking or eating unhealthy diets) that increase their risk of heart disease, it may be difficult to determine the true effect of caffeine on heart disease. In this case, the unhealthy habits would be the confounding variable, and controlling for these variables would be necessary to accurately assess the relationship between caffeine consumption and heart disease.
