solve the system of inequalities

Answer:

15/8 minutes

Step-by-step explanation:

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

where k is a constant.

You are given a t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.  Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]

minutes.

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

We have given,

The time t  for am ice cube to melt. is inversely proportional to the

temperature T of the water in the ice cube is placed.

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

Where k is a constant.

You have given a  t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.

Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80} =\frac{15}{8}[/tex]

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

Hello, I am BrotherEye

Answer:

Regression models are predictive tools. If you want to use them to predict the behavior of an individual, you must set "behavior" as your dependent variable, and you must have indicators and measures for such. You must also identify your explanatory or independent variable likewise you must have indicators and measures for such.

If you have built your model on the basis of collected data, you will be able to predict the value of behavior given a value of the explanatory variable.

Answer:

[tex]a= 2[/tex]

[tex]b = 3[/tex]

Step-by-step explanation:

Given

[tex]p(x,y) = (6,0)[/tex]

[tex]q(x,y) = (3,2)[/tex]

[tex]ax + by = 12[/tex]

Required

Find a and b

In [tex]p(x,y) = (6,0)[/tex], [tex]x = 6[/tex] and [tex]y = 0.[/tex]

This gives:

[tex]a*6 + b*0 = 12[/tex]

[tex]6a = 12[/tex]

Divide by 6

[tex]a= 2[/tex]

In [tex]q(x,y) = (3,2)[/tex]. [tex]x = 3[/tex] and [tex]y = 2.[/tex]

This gives:

[tex]a*3 + b*2 = 12[/tex]

[tex]3a + 2b = 12[/tex]

Substitute 2 for a

[tex]3*2 + 2b = 12[/tex]

[tex]6 + 2b = 12[/tex]

Collect Like Terms

[tex]2b = 12 - 6[/tex]

[tex]2b = 6[/tex]

Divide by 2

40 = (3x-2)(x)

40= 3x^2 - 2x

3x^2 -2x - 40 =0

3x^2 - 12x + 10x - 40 = 0

3x(x - 4) + 10(x -4) = 0

Answer: 0.907

Step-by-step explanation:

The average rate of change in a function from x= a to x = b is given by :-

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Given: [tex]S(x)=573-133(0.987)^x[/tex]

Then, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year will be :

[tex]\dfrac{S(60)-S(40)}{60-40}=\dfrac{573-133(0.987)^{60}-573-133(0.987)^{40}}{20}\\\\=\dfrac{512.34-494.20}{20}\\\\=\dfrac{18.14}{20}\\\\=0.907[/tex]

Hence,  the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per yearr= 0.907

Step-by-step explanation:

                                                                                                           -b

The axis of symmetry can be calculated using this formula:  x = ------

                                                                                                           2a

                                         -(-12)

which in this case is  x = ---------- = 1.  The axis of symmetry is the vertical

                                         2(6)             line x = +1

Thus, x = 1 is the x-coordinate of the vertex.  Normally we'd find the y-coordinate by evaluating the function at x = 1.  Unfortunately your

6x²-12x-25=-7 does not have the form of a quadratic function; such a function does not have the " = " sign in it.

Example:  Suppose we have  6x²-12x-25 = f(x) and we evaluate this function at x = 1:  f(1) = 6(1)^2 - 12(1) - 25 = -31, which (in this example)

leads to the vertex (1, -31).

Answer:

  40 ft by 85 ft

Step-by-step explanation:

The total length of the three "vertical" partitions is ...

  3x = vertical partitions

The total length of the horizontal sides is ...

  2(x +(x +5)) = 4x +10

Then the perimeter is ...

  P = vertical partitions + horizontal sides

  290 = 3x +4x +10

  280 = 7x

  x = 40

  2x+5 = 85

The overall dimensions are 40 ft by 85 ft.
