we are given

(5x^2 -3xy +10y^2) - (12x^2+11xz-7z^2)

we have to subtract

step-1:  Distribute negative sign

=5x^2 -3xy +10y^2-12x^2-11xz+7z^2

step-2:Combine like terms

=5x^2 -12x^2-3xy -11xz+10y^2+7z^2

=-7x^2-3xy -11xz+10y^2+7z^2

we get

=-7x^2-3xy -11xz+10y^2+7z^2............Answer

Answer:

We conclude that at x = 0 and x = -1, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

Therefore, the solution to f(x) = g(x) is:

  • x = -1
  • x - 0

Step-by-step explanation:

Given the table

x                f(x) = 2ˣ - 1                  g(x) = 1/2x

-2                  -3/4                               -1

-1                    -1/2                               -1/2

0                     0                                   0

1                       1                                   1/2

2                     3                                    1

If we carefully observe, we can determine that

at x = 0, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

In other words,

at x = 0

  • f(0) = 0
  • g(0) = 0

Thus,

at x = 0

f(x) = g(x)

Also at x = -1, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

In other words,

at x = -1

  • f(-1) = -1/2
  • g(-1) = -1/2

Thus,

at x = -1

f(x) = g(x)

Summary:

Thus, we conclude that at x = 0 and x = -1, the value of f(x) = 2ˣ - 1 and g(x) = 1/2x is the same.

Therefore, the solution to f(x) = g(x) is:

  • x = -1
  • x - 0

Determine whether the study depicts an observational study or an experiment. Thirty university students are divided into two gro
alex41 [277]

Answer:

The provided study is an experiment.

Step-by-step explanation:

Consider the provided information.

Observational study: In this study observer only observe the subjects, and measure variables of interest without allocating treatments to subjects.

For example: you want to examine the  side effect of smoke on lung.

Experiment study:The researchers are applying treatments to experimental units in the research, then the effect of the treatments on the experimental units is observed.

For example: Flipping a coin

Now consider the provided information:

Thirty university students are divided into two groups. One group receives free tutoring in mathematics comma the other doesn't. After one semester comma scores on final mathematical examinations are compared.

Here, the researcher applying treatment to experimental units.

Thus, the provided study is an experiment.
