Answer: x = 3; y = -2

Step-by-step explanation:

Simultaneous Equations:
3^(2x) x 3^(3y) = 3^0
2x + 3y = 0

2^(2x) x 2^(-0.5y) = 2^7
2x - 0.5y = 7

2x = -3y

-3y - 0.5 y = 7

y = -2

The gymnast trains 5 hours per day making a total of 120 hours in a 4 week period

An equation is a expression that shows the relationship between numbers and variables.

Let x represent the number of hours practiced per day. A gymnast practices 6 days each week, hence:

Number of hours practiced per week = 6x

If she practices a total of 120 hours in a 4- week period. Therefore:

6x hours per week * 4 weeks = 120 hour

24x = 120

x = 5

The gymnast trains 5 hours per day.

These ratios are different because they express the number of laps for two different numbers of hours.

To better understand how these ratios compare, let's simplify the second ratio:

192 laps/ 8 hours = 24, which means the ratio would be 24 laps per hour

This means that the ratios express the same number of laps per hour.

Basically, the two ratios tell us the number of laps but using different hours. In this way, the first ratio expresses the number of laps in only one hour, while the second ratio amplifies this ratio to eight hours.

The reasonable estimate of the probability that it is sunny tomorrow is 25%.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Probability of an event is calculated by dividing the number of desirable outcomes by the total number of events possible.

From the graph, we have,

Number of days weather is sunny = 3

Total number of days = Days weather is sunny + Days weather is cloudy + Days weather is rainy + Days weather is snowy

Total number of days = 3 + 5 + 2 + 2 = 12

Probability that weather is sunny = 3 / 12 = 1/4 = 0.25 = 25%

Hence there is a 25% probability that weather is sunny.

To determine if three points are in a straight line in 3D, you can calculate the vector between the first two points and then check if the third point is in the same direction as the vector.

Straight line is a line that extends infinitely in two opposite directions and has no curves or bends. It is the shortest distance between two points and is the basic form of geometry. A straight line is composed of two end points and all the points in between that make up the line. Straight lines are used to create shapes and constructions in mathematics, science and engineering.

If the dot product of the vector and the point is 0, then the three points are in a straight line. Alternatively, you can calculate the area of the triangle formed by the three points and if it is 0, then the points are in a straight line. Another option is to calculate the determinant of the matrix formed by the three points and if it is 0, then the points are in a straight line. Finally, you can calculate the angle between the two vectors formed by the three points and if it is 0, then the points are in a straight line.

The following are the 5 steps in solving a rational inequality: simplifying the inequality, factoring the numerator and denominator of the inequality, set the numerator and denominator equal to zero.

Solving a rational inequality involves isolating the variable and determining the range of values that make the inequality true.

Simplify the inequality by clearing any fractions: This can be done by multiplying both sides of the inequality by the least common multiple (LCM) of the denominators of the fractions.

Factor the numerator and denominator of the inequality: This can be done to cancel out any common factors between the numerator and denominator.

Set the numerator and denominator equal to zero and solve for the zeros: This can be done to find the values of the variable that make the numerator and denominator equal to zero.

Test the zeros and any critical values: This can be done by substituting the zeros and critical values back into the inequality and determining if they make the inequality true or false.

Plot the solution on the number line: This can be done by plotting the zeros and critical values on a number line and shading the region that makes the inequality true.

The divisibility rule is a concise and practical approach to check, often by looking at the integer's digits, whether a given integer is divisible by a given set divisor without actually executing division. Without actually doing the division procedure, you may quickly discover if a given number can be divided by a defined divisor using the divisibility test. When dividing two numbers exactly, the quotient must be an integer and the remainder must be zero.

Answer: x = 2, y = -3

Step-by-step explanation: From the question,

-3x -3y = 3 ---------- this becomes the first equation

Make y the subject

-3y = 3 + 3x

y = (3 + 3x)/ -3  ----------this becomes our second equation

Substitute the value of y into the first equation

-3x -3(3 + 3x) = 3

-3x -9 + 9x = 3

Collect like terms

-3x + 9x = 3 + 9

6x = 12

Divide both sides by 6

6x/ 6 = 12/ 6

x = 2

Substitute x = 2 into the second equation to find y

y = (3 + 3(2) )/ -3

y = ( 3 + 6) / -3

y = 9/ -3

180 m , ≈ 6.9 seconds

Step-by-step explanation:

let vertical distance be represented by d and time t

given d is directly proportional to t² , then the equation relating them is

d = kt² ← k is the constant of proportion

to find k use the condition , the ball falls 80 m in 4 seconds , then

80 = k × 4² = 16k  ( divide both sides by 16 )

5 = k

d = 5t² ← equation of proportion

(a)

when t = 6

d = 5 × 6² = 5 × 36 = 180 m

(b)

when d = 240

240 = 5t² ( divide both sides by 5 )

48 = t² ( take square root of both sides )

Step-by-step explanation:

The image point of P(x,y) = ( 6 , 5 ) after applying a horizontal reflection is P'(x,y) = (1, 5).

In geometry, a rigid transformation is a transformation applied onto a geometric object such that Euclidean distance in every point of it is conserved. Translations are examples of rigid transformations and are defined by this formula:

P'(x,y) = P(x,y) + T(x,y)                    (1)

Where:

P(x,y) - Original point

T(x,y) - Translation vector

P'(x,y) - Image point

If we know that P(x,y) = (6, 5) and T(x,y) = (5, 0), then the image point is:

P'(x,y) = (6, 5) + (5, 0)

P'(x,y) = (1, -6)

According to the table for a $150,000 mortgage, Lastri's credit score needs to improve by 62 points for her to take a mortgage for $150,000.

The credit score refers to an individual's or entity's creditworthiness rating.

The credit score predicts a person's credit behavior and ability to repay credit.

Financial institutions and lenders use the credit score to determine the amount of credit to offer a borrower, the attached credit risks, and the accompanying interest rate, including monthly payments.

Annual mortgage payments Lastri can afford = $13,900

Monthly payment = $1,158 ($13,900 ÷ 12)

Current credit score = 498

Minimum credit score for a monthly payment of $1,158 = 560

Additional credit score improvement = 62 (560 -498)
