Answer:

x = -7, y = -1

Step-by-step explanation:

Solve the following system:

{12 y = x - 5 | (equation 1)

9 y - 2 x = 5 | (equation 2)

Express the system in standard form:

{-x + 12 y = -5 | (equation 1)

-(2 x) + 9 y = 5 | (equation 2)

Swap equation 1 with equation 2:

{-(2 x) + 9 y = 5 | (equation 1)

-x + 12 y = -5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{-(2 x) + 9 y = 5 | (equation 1)

0 x + (15 y)/2 = -15/2 | (equation 2)

Multiply equation 2 by 2/15:

{-(2 x) + 9 y = 5 | (equation 1)

0 x + y = -1 | (equation 2)

Subtract 9 × (equation 2) from equation 1:

{-(2 x) + 0 y = 14 | (equation 1)

0 x + y = -1 | (equation 2)

Divide equation 1 by -2:

{x + 0 y = -7 | (equation 1)

0 x + y = -1 | (equation 2)

The linear equations derived are:

y= 2x-4 ..................................1)

y=5x+3......................................2)

The slope and y-intercept of a linear equation in two variables are two important characteristics of the equation that can be used to graph the equation on a two-dimensional coordinate system.

The slope of a linear equation in the form of y = mx + b is represented by the coefficient of x, which is m. The slope tells us the steepness of the line and the direction it is moving. If m is positive, the line slopes upward to the right, if m is negative, the line slopes downward to the right.

The y-intercept of a linear equation in the form of y = mx + b is represented by the constant term b. The y-intercept is the point where the line crosses the y-axis. It can be found by setting x=0 and solving for y.

On comparing the equations with the general equation of linear equation in two variables we get:

m1=2 and b1=-4

m2=5 and b2=3

Therefore, The linear equations derived are:

Answer:

This is true because the order of operations applies. In this case, we have to divide the 1/5 by 2 first and then get the result.

Dividing 1/5 by 2 is the same as multiplying 1/5 by 1/2, which is equivalent to multiplying the numerator and denominator by 1/2.

(1/5) * (1/2) = (1 * 1)/(5 * 2) = 1/10

So, (1/5)/2 = 1/10

This is also true because dividing a fraction by another fraction is the same as multiplying the first fraction by the reciprocal of the second fraction. The reciprocal of 2 is 1/2, and so dividing 1/5 by 2 is the same as multiplying 1/5 by 1/2.

That's why the answer is 1/10.

Using the foci and co-vertices, the equation of ellipse is  (x^2/9) + (y^2/9) = 1

An ellipse is defined as the set of all points such that the sum of the distances from the foci to the point is constant. The distance between the foci is 2*c, where c is the distance from the center to either focus.

Given that the foci are at (0, ±3) and the co-vertices are at (±3, 0), we know that the center of the ellipse is at (0, 0) and the distance between the foci is 2c

So the equation of the ellipse with foci at (0, ±3) and co-vertices at (±3, 0) can be written as:

(x²/3²) + (y²/b²) = 1

Where a = 3, b = 9

So, the equation of the ellipse is (x^2/9) + (y^2/9) = 1

Working with a sample rather than an entire population is often more practical and cost-effective. It can also be more accurate since it reduces the chances of sampling bias.

Additionally, it can be faster and more efficient since it requires less data and can be done in a shorter period. Furthermore, a sample can provide more insight into the population as a whole since it is representative of the population, and the results of a sample can be generalized to the entire population. Finally, working with a sample is more manageable and easier to analyze than working with an entire population. This is because a sample has fewer data points, which can make it easier to identify patterns and draw conclusions.

Step-by-step explanation:

Given that installing 6 apps increases the Eric : Ian app ratio from 3:4 to 5:4, you want to know how many more apps Ian needs to install to have the same number as Eric.

We note that the number of apps representing Ian's apps remains at 4 in both ratios, but increasing Eric's apps by 6 changes his number of ratio units from 3 to 5, a change of 2 ratio units. That is, each ratio unit represents 3 apps.

Eric now has 1 more ratio unit (5) than Ian (4), so Ian needs to increase his number by 1 ratio unit, or 3 apps.

Ian must install 3 apps to have the same number as Eric.

__

Additional comment

To see how many actual apps we're talking about, multiply the ratios by 3. The initial Eric : Ian app ratio was 9 : 12. After Eric installed 6, it became (9+6) : 12 = 15 : 12. So, Ian needs to install 15-12 = 3 apps to have as many as Eric.

The domain and range of y = 5^x is all real numbers.

The domain of y = 5^x is all real numbers, x. There are no restrictions on the input value for x, so any real number can be used as the exponent.

The range of y = 5^x is all positive real numbers, y. This is because the base of the exponential function, 5, is positive and the exponent, x, can be any real number. As the exponent increases, the value of the function will also increase and the function will approach positive infinity. Similarly, as the exponent decreases, the value of the function will also decrease and approach zero. Therefore, the range of y = 5^x is all positive real numbers, y.

Thus,

area of region A is πa²/8

area of region B is πb²/8

area of region C is πc²/8

The triangle formed is a right angled triangle, with hypotenuse a and legs b and c. By Pythagoras theorem
