How do you write 9 more than a number?

Answer:

x=4      y=-1

Simplify:

100+43y over 3 = 19

Step-by-step explanation:

-3x-8y=20

-5x+y=19

The solution of the given system of equation is (8, -22).

In the given question we have to find the solution to the system of equations:

y = -4x + 10 and y = -2x - 6

We can solve the system of equation using the substitution method.

In substitution method we have to put the the value of one variable from one equation to the other equation.

We have to equations:

y = -4x + 10...................................(1)

y = -2x - 6.............................(2)

Now putting the value of y from the equation 1 in equation 2

-4x + 10 = -2x - 6

Add 6 on both side we get

-4x + 16 = -2x

Add 4x on both side, we get

2x = 16

Divide by 2 on both side, we get

x = 8

Now the value of x is 8.

Now putting the value of x in equation 1

y = -4(8) + 10

y = -32 + 10

y = -22

Hence, the solution of the given system of equation is (8, -22).

highway: 70 × 2 = 140 miles

side roads: 35 × 1 = 35 miles

total distance: 140 miles + 35 miles = 175 miles

im sorry if the answer is wrong :)

The correct answer is c.) the probability of getting a number less than 3 is equal to 0.33 but does not change the probability of the next trial.

The probability of getting a number less than 3 on a standard die is always equal to 0.33, regardless of the number of times the die is rolled. The probability of an event occurring does not change based on the number of times the event has occurred in the past. Each roll of the die is an independent event, meaning that the outcome of each roll does not affect the probability of the next roll.

The total distance traveled by the cows are 3.58 meters. To calculate that we need to calculate fourth area before.

It sounds like you are trying to solve a problem involving two cows grazing in a field and the area that they graze. Here is a possible solution:

We can use the formula for the area of a quadrilateral to solve for the fourth side:

Area = (1/2) x (12 cm) x (fourth side)

Solving for the fourth side, we get:

Fourth side = (20 cm)/(12 cm) = 1.67 meters

Finally, add up the lengths of the four sides to find the total distance traveled by the cows:

Total distance = (1.67 meters) + (12 cm) + (1.67 meters) + (12 cm) = 3.58 meters

Discontinuity can be determined by looking for sudden changes in values or jumps in the graph of the function. If there is a break or gap in the graph, the function is discontinuous.

Discontinuity occurs when a function fails to be defined at a certain point within its domain, resulting in a sudden change in the graph of the function. Discontinuity can be determined by plotting the graph and looking for sudden changes in values or jumps in the graph. If the graph shows a break or gap, then the function is discontinuous. Discontinuity can also be determined by examining the behavior of the function at a certain point. If the function values diverge as the point is approached from either side, then the function is discontinuous at that point. Additionally, a function can be discontinuous at a point if it does not obey the rule of continuity, which is that the function's value must be equal to the limit of the function as the point is approached from both sides. If the limit does not exist at a point, then the function is discontinuous at that point.

Step-by-step explanation:

The measure of segments mAG, mAC, and mBC are 11.4, 16.1 and 7.1 respectively,

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,
Apply Pythagoras theorem in triangle ABG,

mAG = √[7² + 9²]
mAG = √[49 + 81]
mAG = √[130] = 11.4
Apply Pythagoras theorem in triangle BGC,
mBC = √[10² - 7²]
mBC = √51
mBC = 7.1

Now

mAC = mAB  + mBC
mAC = 9 + 7.1
mAC = 16.1

Thus, the segments mAG, mAC, and mBC have measures of 11.4, 11.1, and 7.1, respectively.

The median of 4 and 7 is 5.5.

The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.

The data set's median is the value in the center. Put all the numbers in ascending or descending order, and then choose the middle number to determine the median. There will only be one middle integer if the number of data points is odd. If the number of data points is even, you must choose the middle two numbers, add them together, and divide by two. Your median will be that value.

The mean of these middle values is (4+7)/2 = 11/2= 5.5

The simple interest is $6,240.00.

The term simple interest refers the interest that is only calculated on the initial sum borrowed or deposited.

Here we need to find  the simple interest on $6000 from 16 may 2010 to 9 October 2010 at 10% per annum.

While we looking into the given question, we know te following values,

Principal amount = $6000

Time period = 16 may 2010 to 9 October 2010

The number of days between 16 may 2010 to 9 October 2010 is

=> 146 days.

Here we have the interest for 1 year,

So, the time period is written as,

And then we have to put time into years for simplicity,

146 days / 365 days/year = 0.4 years.

And the interest rate = 10%

Here we have to convert R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year.

Now, we have to apply the values on the formula, then we get by solving our equation:

A = 6000(1 + (0.1 × 0.4)) = 6240

A = $6,240.00

Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 10% per year for 0.4 years (146 days) is $6,240.00.

Population parameters are used to estimate sample statistics, and this is true.

Population parameters are used to describe the characteristics of a population, such as the mean, median, and standard deviation, and are used to make inferences about a population. Sample statistics, on the other hand, are used to describe the characteristics of a sample of a population. For example, a sample statistic could be the mean of a sample of people's heights.

To estimate sample statistics, population parameters must first be known. For example, the sample mean can be estimated using the population mean. If the population means are unknown, then the sample means can be estimated using the sample mean.

In conclusion, population parameters are used to estimate sample statistics, and this is true. Population parameters provide useful information about a population that can be used to make inferences about a sample. Knowing the population parameters allows researchers to make more accurate estimates of sample statistics, which in turn can be used to make more reliable inferences about a population.

from the drawing BC = EF

we solve with an equation

x - 4 = 19

x = 19 + 4

x = 23

The solution of the given system of equation is (-19, 55).

In the given question we have to find the solution to the system of equations:

y = -3x-2 and 5x + 2y = 15

We can solve the system of equation using the substitution method.

In substitution method we have to put the the value of one variable from one equation to the other equation.

We have to equations:

y = -3x-2...................................(1)

5x + 2y = 15.............................(2)

Now putting the value of y from the equation 1 in equation 2

5x + 2(-3x-2) = 15

Now solving the equation using the distribution method.

5x - 6x - 4 = 15

Simplifying

-x - 4 = 15

Add 4 on both side we get

-x = 19

Now the value of x is -19.

Now putting the value of x in equation 1

y = (-3)*(-19)-2

y = 57-2

y = 55

Hence, the solution of the given system of equation is (-19, 55).
