d + r² = w

The equation of the line in the point-slope form is y - 15 = [tex]-\frac{3}{2}[/tex] (x - 10)

Step-by-step explanation:

The point-slope form of a linear equation is [tex]y-y_{1}=m(x-x_{1})[/tex] , where

∵ Point A = (10 , 15)

∵ The x-coordinate of the second point is 125% of x-coordinate

  of point A

∴ x-coordinate of second point = [tex]\frac{125}{100}[/tex] × 10

∴ x-coordinate of second point = 12.5

∵ The y-coordinate of the second point is 75% of y-coordinate

  of point A

∴ y-coordinate of second point = [tex]\frac{75}{100}[/tex] × 15

∴ y-coordinate of second point = 11.25

∴ The coordinates of the second point are (12.5 , 11.25)

Let us find the slope of the line by using the rule of it above

∵ [tex](x_{1},y_{1})[/tex] = (10 , 15)

∵ [tex](x_{2},y_{2})[/tex] = (12.5 , 11.25)

∴ [tex]m=\frac{11.25-15}{12.5-10}=\frac{-3.75}{2.5}=-\frac{3}{2}[/tex]

Now we can write the equation

∵ The point-slope form is [tex]y-y_{1}=m(x-x_{1})[/tex]

∵ [tex]m=-\frac{3}{2}[/tex]

∵ [tex](x_{1},y_{1})[/tex] = (10 , 15)

- Substitute these values in the form of the equation

∴ y - 15 = [tex]-\frac{3}{2}[/tex] (x - 10)

The equation of the line in the point-slope form is y - 15 = [tex]-\frac{3}{2}[/tex] (x - 10)

Answer: [tex]d)x=4[/tex]

Step-by-step explanation:

[tex]a)x=-1\\b)x=0\\c)x=3\\d)x=4[/tex]

By definition, a relation is a function if and only if each input value has one and only one output value.

It is important to remember that the input values are the values of "x" and the output values are the values of "y".

Observe the graph attached.

You can identify in the graph that the function f(x) and the function g(x) intersect each other at the following point:

[tex](4,3)[/tex]

Where the x-coordinate (input value) is:

[tex]x=4[/tex]

And the y-coordinate (output value) is:

[tex]y=3[/tex]

Therefore, you can conclude that the input value that produces the same output value for the  two functions on the graph, is:

[tex]x=4[/tex]

For this case we must find the solution set of the given inequalities:

[tex]-15x + 4 <109[/tex]

We subtract 4 from both sides of the inequality:

[tex]-15x <109-4\\-15x <105[/tex]

We divide between 15 on both sides of the inequality:

[tex]-x <\frac {105} {15}\\-x <7[/tex]

We multiply by -1 on both sides taking into account that the sense of inequality changes:

[tex]x> -7[/tex]

The solution is given by all values of x greater than -7.

[tex]-6x + 70> -2[/tex]

Subtracting 70 from both sides of the inequality:

[tex]-6x> -2-70\\-6x> -72[/tex]

We divide by 6 on both sides of the inequality:

[tex]-x> - \frac {72} {6}\\-x> -12[/tex]

We multiply by -1 on both sides taking into account that the sense of inequality changes:

[tex]x <12[/tex]

Thus, the solution set is given by:

[tex]x> -7\ U\ x <12[/tex]

Therefore the solution is all real numbers.

Answer:

All real numbers.

Answer:

1.  x > 4

2.  m < 2

3.  x > 2

4.  x < -6

Step-by-step explanation:

These 4 inequalities will be solved the same way we solve equations. We take variables to one side and numbers to another and use algebra to solve. Each of them are solved shown below:

1.

[tex]4+6x<x+6x\\4+6x<7x\\4<7x-6x\\4<x[/tex]

so x is greater than 4, we can write (variable first):

x > 4

2.

[tex]m+16>8m+2\\16-2>8m-m\\14>7m\\\frac{14}{7}>m\\2>m[/tex]

so m is less than 2, we can write:

m < 2

3.

[tex]5x-1>13-2x\\5x+2x>13+1\\7x>14\\x>\frac{14}{7}\\x>2[/tex]

so x is greater than 2, we can write:

x > 2

4.

[tex]-3x-2>-x+10\\-2-10>-x+3x\\-12>2x\\\frac{-12}{2}>x\\-6>x[/tex]

so x is less than -6, we can write:

x < -6

Final answer:

The area of a rectangular field that is 400 meters long and 350 meters wide is calculated by multiplying the length and width in meters to get square meters and then converting to square kilometers. The field's area is 0.14 square kilometers.

Explanation:

To calculate the area of a rectangular field, you multiply the length by the width. The area is usually given in square units.

In this case, the field is 400 meters long and 350 meters wide. To find the area in square meters, we do the following calculation:

Area = Length × Width

Area = 400 m × 350 m

Area = 140,000 m2

To convert square meters to square kilometers, you need to remember that 1 square kilometer equals 1,000,000 square meters. Therefore, you divide the area in square meters by 1,000,000 to get the area in square kilometers:

Area in square kilometers = Area in square meters / 1,000,000

Area in square kilometers = 140,000 m2 / 1,000,000

Area in square kilometers = 0.14 km2

The area of the field is 0.14 square kilometers.

To find the area of the rectangular field in square kilometers, the measurements of 400 meters and 350 meters must first be converted to kilometers, resulting in an area of 0.14 square kilometers.

To calculate the area of a rectangular field in square kilometers, we can use the formula for the area of a rectangle which is length × width. First, we need to convert the measurements into the same unit, so we will convert meters to kilometers. We know that 1 kilometer is equivalent to 1000 meters. Therefore, a field that is 400 meters long is 0.4 kilometers long (400 ÷ 1000 = 0.4 km), and a field that is 350 meters wide is 0.35 kilometers wide (350 ÷ 1000 = 0.35 km).

Now, with both measurements in kilometers, we can find the area:

Answer:

D

Step-by-step explanation:

To determine which ordered pair is a solution.

Substitute the x and y values into the inequalities.

Note that both must be true for the pair to be a solution of the system.

(4, 8)

8 > 2(4) → 8 > 8 ← False

8 > 7 ← True

(0, 0)

0 > 2(0) → 0 > 0 ← False

0 > 7 ← False

(3, 7)

7 > 2(3) → 7 > 6 ← True

7 > 7 ← False

(1, 9)

9 > 2(1) → 9 > 2 ← True

9 > 7 ← True

Thus (1, 9) is a solution to the system of equations. → D

The ordered pair (1,9) is the solution to the system of inequalities.

To determine which ordered pair is a solution to the system of inequalities, we need to check if each pair satisfies both inequalities. Let's check:

A. (4,8): For y > 2x, 8 > 2(4) = 8 > 8, which is false. For y > 7, 8 > 7, which is true. Therefore, (4,8) is NOT a solution to the system.

B. (0,0): For y > 2x, 0 > 2(0) = 0 > 0, which is false. For y > 7, 0 > 7, which is false. Therefore, (0,0) is NOT a solution to the system.

C. (3,7): For y > 2x, 7 > 2(3) = 7 > 6, which is true. For y > 7, 7 > 7, which is false. Therefore, (3,7) is NOT a solution to the system.

D. (1,9): For y > 2x, 9 > 2(1) = 9 > 2, which is true. For y > 7, 9 > 7, which is true. Therefore, (1,9) is a solution to the system.

Thus, the ordered pair (1,9) is the solution to the system of inequalities.

As we know that-

If a line segment AB is with endpoints ([tex]x_{1}, y_{1}[/tex]) and  ([tex]x_{2}, y_{2}[/tex] then the mid points C are-  

C = ([tex]\frac{x_{1} + x_{2}  }{2}[/tex] , [tex]\frac{y_{1} + y_{2}  }{2}[/tex] )

Here,

A ( [tex]x_{1} = 9, y_{1} = 8[/tex] and B ( [tex]x_{2} = 3, y_{2} =5[/tex]

Answer: base = 20 inches , height = 8 inches

Step-by-step explanation:

The formula fro calculating the area of  a triangle , given the base and the height is given as ;

A = [tex]\frac{1}{2}[/tex]bh

The ratio of its base to the height is given as 5: 2 , this means that

2b = 5h , that is

b = [tex]\frac{5h}{2}[/tex]

Substitute this into the formula for finding area , that is

80 = [tex]\frac{1}{2}[/tex] X [tex]\frac{5h}{2}[/tex] X h

80 = [tex]\frac{5h^{2}}{4}[/tex]

Therefore :

[tex]5h^{2}[/tex] = 80 x 4

[tex]5h^{2}[/tex] = 320

[tex]h^{2}[/tex] = 320 / 5

[tex]5h^{2}[/tex] = 64

h = 8 inches

Substitute h = 8 into b = [tex]\frac{5h}{2}[/tex] , then

b = 20 inches

Therefore , the base of the triangle is 20 inches and the height is 8 inches

linear equation in Standard form that can be used to determine how many of each prize Caleb can buy is [tex]1.25x+ 2.50y = 25[/tex]

Step-by-step explanation:

Given:

Total cost spent on prizes for games = $25

Cost of one lip balm = $1.25

Cost of one mini notebook  = $2.50

A) linear equation in STANDARD FORM that can be used to determine how many of each prize she can buy.

Let the number of lip balms be x and the number of mini note books be y. Then

[tex]1.25x+ 2.50y = 25[/tex]

B. Graph the equation using x- and y- intercepts.

Now by trial and error method

[tex]1.25(0)+ 2.50(10) = 25[/tex]

[tex]1.25(2)+ 2.50(9) = 25[/tex]

[tex]1.25(4)+ 2.50(8) = 25[/tex]

[tex]1.25(6)+ 2.50(7) = 25[/tex]

[tex]1.25(8)+ 2.50(6) = 25[/tex]

[tex]1.25(10)+ 2.50(5) = 25[/tex]

[tex]1.25(12)+ 2.50(4) = 25[/tex]

[tex]1.25(14)+ 2.50(3) = 25[/tex]

[tex]1.25(16)+ 2.50(2) = 25[/tex]

[tex]1.25(18)+ 2.50(1) = 25[/tex]

[tex]1.25(20)+ 2.50(0) = 25[/tex]

Thus Caleb can buy 0,2,4,6,8,9,10,12,14,1,6,18,20 lip balms and

0,1,2,3,4,5,6,7,8,9,10 mini note books respectively
