The sum of two numbers is 12. The difference of the two numbers is 6. What are the two numbers?

Answer:

[tex]1+\sqrt{1190}[/tex] and [tex]\sqrt{1190}-11[/tex]

Step-by-step explanation:

Let the length in meters be [tex]l[/tex]. Then, the width is [tex]l-12[/tex].

[tex]l(l-12)=1189 \\ \\ l^2-12l=1189 \\ \\ l^2-2l-1189=0 \\ \\ l=\frac{2 +\sqrt{(-2)^2-4(1)(-1189)}}{2(1)} \text{ } (l>0) \\ \\ l=1+\sqrt{1190} \\ \\ \implies l-12=\sqrt{1190}-11[/tex]

The rate of the boat in still water is 45.5 km/hr and  the rate of the current is 100.5 km/hr.

A motorboat travels 74 km in 2 hours going upstream.

Rate = Distance/time

Rate = 74 /2

Rate = 36 km/hr

It travels 110 km going downstream

Rate = Distance/time = 110/2

Rate  = 55 km/hr

Equations:

Upstream: b-c = 36 km/hr

Downstrm: b+c = 55 km/hr

Add and solve for b

2b = 36 km/hr + 55 km/hr

2b = 91 km/hr

Divide both side by 2b

b = 91 km/hr /2

b = 45.5 km/hr (speed of the boat)

Solve for c

b+c = 55

45.5+ c = 55

c = 55 + 45.5

c = 100.5 km/hr (speed of the current)

Therefore  45.5 km/hr  and  100.5 km/hr are the speed.

The solutions of the inequality are given by:

x > -3

Here we have the following inequality:

-(4x - 5) + 16x > -31

To solve this, we need to isolate the variable x in one of the sides of the inequality, so let's do that.

-(4x - 5) + 16x > -31

-4x + 5 + 16x > -31

(-4 + 16)*x + 5 > -31

12x + 5 > -31

12x > -31 - 5

12x> -36

x > -36/12

x > -3

Answer:

The three numbers are -4, 0, and 1.

The sum of three numbers is -3: -4 + 0 + 1 = -3

If the second number is subtracted from the sum of the first and third numbers, the result is -3: (-4 + 1) - 0 = -3

If the third number is subtracted from the sum of the first and second numbers, the result is -5: (-4 + 0) - 1 = -5

Step-by-step explanation:

x --> first number

y --> second number

z --> third number

x + y + z = -3

(x + z) - y = -3

(x + y) - z = -5

x = -3 - y - z

(-3 - y - z + z) - y = -3

-3 - y - y = -3

-2y = 0

y = 0

(-3 - y - z + y) - z = -5

-3 - z - z = -5

-3 - 2z = -5

-2z = -2

z = 1

Answer: x = -2, y = 3

Step-by-step explanation:

Given that,

-9x+2y = 24..................................(i)

x = 10-4y.......................................(ii)

From equation (i)

-9(10-4y) + 2y = 24  [as x = 10-4y]

=> -90 +36y + 2y = 24

=> 38y = 90 + 24

=> 38y = 114

=> y = 114/38

Therefore, y = 3

Again,

x = 10 - 4(3)  [as y = 3]

=> x = 10-12

Therefore, x = -2

Here, x = -2 and y = 3

First, we know that the experimental value is 13.3, and the true value 13.6. After plugging in, we get |13.3 - 13.6| = -0.3 which is just 0.3 as it is the absolute value. Then, we divide it by 13.6 which brings us the equation 0.3/1.36 which rounds to 0.022. Continuing, we multiply it by 100 which gets our answer of 2.2. The nearest percent is 2, so our answer is 2 percent.

The coordinates of the point which we want to find the distance from the line are given as follows:

(x0,y0).

The equation that obtains the shortest distance of the point (x0, y0) to the line ax + by + c = 0 is presented as follows:

[tex]D = \frac{|a(x_0) + b(y_0) + c|}{\sqrt{a^2+b^2}}[/tex]

The line for this problem is given by the rule presented as follows:

y = x - 14.

In standard notation, it is defined by the rule presented as follows:

x - y - 14 = 0.

Hence the coefficients are presented as follows:

a = 1, b = -1, c = -14.

The point has the coordinates given as follows:

(12,6).

Hence:

x0 = 12, y0 = 6.

Thus the distance from the point to the line is obtained as follows:

[tex]D = \frac{|a(x_0) + b(y_0) + c|}{\sqrt{a^2+b^2}}[/tex]

No,  the slope of a horizontal line y=6 is,  zero not negative.

What is a Slope?

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = change in y/change in x = Δy/Δx

Where “m” is the slope of a line.

Generally, the slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says (x1,y1) and (x2,y2) can be easily determined by finding the difference between the coordinates of the points. The slope is usually represented by the letter ‘m’.

Slope Formula

If P(x1,y1) and Q(x2,y2) are the two points on a straight line, then the slope formula is given by:

Slope, m = Change in y-coordinates/Change in x-coordinates = Δy/Δx

m = (y2 – y1)/(x2 – x1)

In the given equation of line y=6 .

The line crosses the y-axis at 6, as the line is always at that value. As it is a horizontal line, the slope is zero.

The equation y = 6 means for each and every value of x, y will be equal to 6.

This is the definition of a horizontal line.

By definition, the slope of a horizontal line is m = 0

When x = 0 then y = 6

Therefore, the y-intercept is: (0, 6).

Hence , the the slope of a horizontal line , m = 0.
