a 65 foot ladder is leaning against a well. Its lower end is 25 feet away from the wall. How much farther away will it be if upper end is moved down 8 feet?

Answer:

(x,y)=(-5,5)

Step-by-step explanation:

[tex]10x + 8y = -10\\\underline{7x + 10y = 15}\\-44y=-220\\y=\cfrac{220}{44} \\y=5[/tex]

[tex]10x+8y=-10\\10x+8\times 5=-10\\10x+40=-10\\102=-10-40\\10x=-50\\x=-50/10\\x=-5[/tex]

Answer:

Answer:1200

Step-by-step explanation:

Consider the cost price to be x.

1st equation x - (15/100)x = x + (20/100)    ...15% discount and gain of 20%

2nd equationx - (25/100)x = x + 120           ....25% discount and a gain of 120Rs

Solving above equations by subtracting we get

(10/100)x = (20/100)x - 120

Solving LHS and RHS..(10/100)x =120

x=1200

2x = 2 x 25?

50 + ? = 150

50 + 100 = 150

x = 50?

2x + 50 = 150

2 x 50 + 50 = 150

100 + 50 = 150

The measure of x is 50.

Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines. Because they are opposite each other, they are also known as vertically opposite angles.

Using Vertical Angle property as

(50+ 2x) = 150

So, subtract 50 from side we get

50 + 2x - 50= 150 - 50

2x = 100

Now, divide both side by 2 we get

2x/2 = 100 / 2

x = 50

The total employee benefits of Trevor with no job expenses and gross pay of $28600 is 17.1%. Option d is the correct option.

Total employment compensation is equal to the sum of gross pay and employment benefit subtracted with any job expenses.

Trevor’s total employment compensation is $33,500. Trevor has no job expenses and his gross pay is $28,600.

Let the total employee benefits is x. Therefore, using the above definition of total employment compensation,

[tex]33500=28600+x-0\\[/tex]

Solve it for x as,

[tex]x=33500-28600\\x=4900[/tex]

In the percentage form,

[tex]x=\dfrac{4900}{28600}\times100\\x=17.1\%[/tex]

Hence, the total employee benefits of Trevor with no job expenses and gross pay of $28600 is 17.1%. Option d is the correct option.

Answer:

Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]

Equation of the line: [tex]y=mx+b[/tex]

Add in the slope in place of ([tex]m[/tex])

[tex]y=-1x+b[/tex]

Add in the x value of the given point in place of ([tex]x[/tex])

[tex]y=(-1)\frac{1}{2}+b[/tex]

Add in the y value of the given point in place of ([tex]y[/tex])

[tex]0=(-1)\frac{1}{2} + b[/tex]

—

Solve:

[tex]0=(-1)\frac{1}{2} +b[/tex]

Multiply -1 and [tex]\frac{1}{2}[/tex]

[tex]-1 *\frac{1}{2}=-\frac{1}{2}[/tex]

So,

[tex]0=-\frac{1}{2} +b[/tex]

Now, add [tex]-\frac{1}{2}[/tex] to 0

      [tex]0=-\frac{1}{2} +b[/tex]

     [tex]+\frac{1}{2}[/tex]   [tex]+\frac{1}{2}[/tex]

#540

Step-by-step explanation:

Alan saved $180 in each month

and we have 12 months in a year so we say

$180=12

x=36

here we cross multiply then we have 180 * 36 which is equal to $6480 after that we divide it by 12 and that's $540

Note: I got 36 months because 12 months in a year so multiply by three years that's 36 months

Given the second difference, the table is quadratic.

A linear function is a function that has a single variable raised to the power of 1. An example is x + 2. A quadratic function is a function that usually has a single variable and it is raised to the power of 2. An example is 2x² + 10x + 25.

First differences:

21 - 11 = 10

35 - 21 = 14

53 - 35 = 18

75 - 53 = 22

Due to the fact that the first difference is not the same, the function is not a linear function.

Second difference:

14 - 10 = 4

18 - 14 = 4

22 - 18 = 4

Due to the fact that the second difference is fairly constant, the function is a quadratic function.

Answer:

5 cm by 4 cm

Step-by-step explanation

A = L x W    20 = L x W

P = 2L + 2W    (18 = 2L + 2W)/2

9 = L + W      W = 9 - L

20 = L (9 - L)    20 = 9L - L^2

L^2 - 9L + 20 = 0    (L - 4)(L - 5) = 0

L = 4  L = 5

The longer one is the length, so L = 5, and W = 4.
