what is the answer?

Answer:

Option 3: (5, 1)

Step-by-step explanation:

There are several ways of solving for systems of linear equations, either through graphing, substitution, or elimination.  

The graphing method is the easiest, as you only need to plot points on the graph using the y-intercepts and the slopes.  

I will be demonstrating the graphing method.  

Given the systems of linear equations:  

Equation 1:  y = x - 4

where the slope, m = 1, and y-intercept (0, -4).

Equation2: y = -x + 6

where the slope, m = -1, and y-intercept (0, 6).

The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b).

For Equation 1, plot the y-intercept, (0, -4) on the graph. Then use the slope, m = 1 (rise 1 unit, run 1 unit) to plot other points on the graph. Repeat this process until you have enough points to connect a line with.  

Repeat these same procedures for graphing Equation 2, start by plotting its y-intercept at (0, 6), and its slope, m = -1 (down 1 unit, run 1 unit).

The intersection of both lines occurs at point, (5, 1), which is solution to the given systems of linear equations.  Therefore, the correct answer is the third option, (5, 1).

Attached is the screenshot of the graphed systems of linear equations, where it shows the point of intersection at (5, 1).

2x + 5x = 43 - 15

7x = 28

x = 28/7

x = 4

Answer:

x = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation

2x +15 = 43 - 5x

2x +15 = 43 + - 5x

2x +15 = - 5x + 43

Step 2: Add 5x to both sides

2x + 15 + 5x= - 5x + 43 + 5x

7x +15 = 43

Step 3: Subtract 15 from both sides.

7x +15 -15 = 43 - 15

7x = 28

Step 4: Divide both sides by 7.

7x/7 = 28/7

Answer: x = 81, y = 17

Step-by-step explanation:

x + y = 98

x/y = 4/13/y

x/y = 4y + 13/ y

x = 98 - y

(98 - y) / y = (4y+ 13) / y

Therefore

98 - y = 4y + 13

Collect like terms

-4y - y = 13 - 98

-5y = -85

Divide both sides by-5

y = 17

x = 98 - y

x = 98 - 17

x = 81

The two numbers​ x and y are 81 and 17 respectively.

Quotients are the number that is obtained by dividing one number by another number.

Dividend ÷ Divisor = Quotients

Given that the sum of two numbers is 98.

Let x and y be the two numbers

x + y = 98

Thus, the larger number is divided by the smaller quotient is 4 with a remainder of 13.

x/y = 4/13/y

x/y = 4y + 13/ y

x = 98 - y

(98 - y) / y = (4y+ 13) / y

Therefore,

98 - y = 4y + 13

Collect like terms;

-4y - y = 13 - 98

-5y = -85

Divide both sides by-5;

y = 17

x = 98 - y

x = 98 - 17

x = 81

Therefore, the two numbers​ x and y are 81 and 17 respectively.

4x-3y=18

3y=4x-18

  y=4/3x-6

By y=mx+c , Slope of line 4x-3y=18 is 4/3

Since the required line is perpendicular to the line 4x-3y=18 ,

slope of required line * Slope of line 4x-3y=18 = -1

slope of required line = -1/(4/3) = -3/4

Since the required line passes through (8,-8)

By point-slope form,

y-(-8)= -3/4(x-8)

      y= -3/4x-2

Here is the answer and explanation all together

The largest area of an isosceles triangle that is inscribed in a circle of radius 3 units is 3.897 sq. units approx.

To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.

Putting those values of x in the second rate of function, if results in negative output, then at that point, there is maxima. If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.

For this case, we can construct a general circle and a variable isosceles triangle in it.

Let the radius of the circle be 'r' units.

For isosceles triangle inscribed in that circle, its vertex(intersection of two congruent sides) be fixed, and other two vertex are allowed to move equally on both the sides of that first vertex.

Those rest two vertices make a chord in that circle. Let the perpendicular distance from the center be 'd' units of that chord.

Then, by Pythagoras theorem for triangle OBD, we get:

[tex]|OB|^2 = |OD|^2 + |BD|^2\\|BD| = \sqrt{|OB|^2 - |OD|^2}\\|BD| = \sqrt{r^2 - d^2} \: \rm units[/tex]

Thus, as perpendicular from center to a chord bisects it, we get:

[tex]|BC| = |BD| + |DC| = |BD| + |BD| = 2\sqrt{r^2 - d^2}[/tex]

The distance from the first vertex (A) to the mid of the line segment BC is: r - d units.

Thus, area of the considered isosceles triangle is:

[tex]A = f(r,d) = \dfrac{1}{2} \times (r - d) \times 2\sqrt{r^2 - d^2} = (r-d)^{1.5}(r+d)^{0.5}[/tex]

At r = 3 units, we get:

[tex]f(3,d) = g(d) = (3-d)^{1.5}(3+d)^{0.5}[/tex]

Finding the value of 'd' for which the function g(d) becomes maximum will give us the maximum area.

Finding first and second derivative of g(d) with respect to 'd', we get:

[tex]g(d) = (3-d)^{1.5}(3+d)^{0.5}\\g'(d) = -1.5(3-d)^{0.5}(3+d)^{0.5} + 0.5(3+d)^{-0.5}(3-d)^{1.5}\\g''(d) = -1.5[-0.5(3-d)^{-0.5}(3+d)^{0.5}] + 0.5[-0.5(3+d)^{-1.5}(3-d)^{1.5}]\\[/tex]

Putting first rate = 0 to find the critical points, we get:

[tex]g'(d) =- 1.5(3-d)^{0.5}(3+d)^{0.5} + 0.5(3+d)^{-0.5}(3-d)^{1.5} = 0\\3(3-d)^{0.5}(3+d)^{0.5} = (3+d)^{-0.5}(3-d)^{1.5}\\3(3+d) = (3-d)\\9 + 3d = 3 - d\\d = 1.5[/tex]

At d = 1.5,  the second rate of g(d) evaluates to:

[tex]g''(1.5) = -1.5[-0.5(3-1.5)^{-0.5}(3+1.5)^{0.5}] + 0.5[-0.5(3+1.5)^{-1.5}(3-1.5)^{1.5}]\\g''(5) = 0.75(1.5)^{1.5}(4.5)^{0.5} -0.25(4.5)^{-1.5}(1.5)^{1.5}\\g''(5) =[/tex]

The area of the isosceles triangle is maximum, and is evaluated as:

[tex]A_{max} = f(3,1.5) = g(1.5) = (3-1.5)^{1.5}(3+1.5)^{0.5} \approx 3.897 \: \rm unit^2[/tex]

Thus, the largest area of an isosceles triangle that is inscribed in a circle of radius 3 units is 3.897 sq. units approx.
