Answer:

125

Step-by-step explanation:

131.25   105

of      100

Cross multiply process

131.25x100=108x?

131.25x100=13125

13125=108?

13125/108=?

Answer:

y = x + 5          

Step-by-step explanation:

1) First, find the slope of the line [tex]x-y = 4[/tex]. We can do this by setting it up in slope-intercept form, represented by the equation [tex]y = mx + b[/tex]. Whatever [tex]m[/tex] or the coefficient of the x-term is will be the slope. Isolate y in the equation:

[tex]x-y = 4\\-y = -x+4\\y = x -4[/tex]

So, the slope of the given equation is 1. Parallel lines share the same slope, thus the slope of the new line will be 1 as well.

2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line in point-slope form. Substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] in the formula.

Since [tex]m[/tex] is the slope, substitute 1 for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through, substitute the x and y values of (-6, -1) into those places as well. Then, isolate y in the resulting equation to put the equation in slope-intercept form and find the answer:  

[tex]y-(-1) = 1 (x-(-6))\\y + 1 = 1 (x + 6)\\y + 1 = x + 6\\y = x + 5[/tex]

Answer:

  (x +3)(x +1)(x -2)

Step-by-step explanation:

A graphing calculator is a good tool for finding factors fast. Each zero (p) gives rise to a factor (x -p).

The graph shows zeros at -3, -1, and 2, so your factorization is ...

  (x +3)(x +1)(x -2)

Answer:

1) The car can travel 623.3 km with 85 liters of petrol.

2) The car owner has to pay $303.8.

Step-by-step explanation:

1) The distance traveled with 85 L of petrol can be found as follows:

[tex] d = \frac{330 km}{45 L}*85 L = 623.3 km [/tex]

Hence, the car can travel around 623 km with 85 liters of petrol.

2) If the liter of petrol costs $2.25, then the amount of petrol that the car owner has to pay to travel a distance of 990 km is:

[tex]x = \frac{\$ 2.25}{1 L}*\frac{45 L}{330 km}*990 km = \$ 303.8[/tex]

Therefore, the car owner has to pay $303.8.

I hope it helps you!

Answer: Reduction, 1/5

Because the image is smaller than the pre-image, it would be a reduction. Then you would count the length of one side of the Images. The length of the pre-image is 20 and the new image is 4. Then you would make a ratio of the new image to the pre-image which is 4/20, which simplifies to 1/5.

Hope this helps!

The scale factor of the dilation will be 1/4.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Now,

Since, The blue figure is a dilation image of the black figure.

And, The origin is the center of dilation.

Here, The length of black figure = 16 units

And, The length of blue figure = 4 units

So, The scale factor of the dilation = 4/16

                                                      = 1/4

Answer:

x<20

Step-by-step explanation:

Building linear functions for each situation, the inequality is:

[tex]18x + 100 < 15x + 160[/tex]

------------------

Choice A:

Thus, the cost of inviting x guests is given by:

[tex]C_a(x) = 18x + 100[/tex]

Choice B:

Thus, the cost of inviting x guests is given by:

[tex]C_b(x) = 15x + 160[/tex]

A cost less than B, thus, the inequality is:

[tex]C_a(x) < C_b(x)[/tex]

[tex]18x + 100 < 15x + 160[/tex]
