Solve the systems of equations y=2x and y=-x - 6

Mathematics
1 answer:
slava [35]3 years ago
7 0

Answer:

y = -4

x = -2

Step-by-step explanation:

Hi there...

y = 2x

y = -x - 6

Since why is equal to 2x, we can plug it in for y in the second equation. Here's what I mean...

2x = -x - 6

add x on both sides...

3x = -6

divide by 3 on both sides...

x = -2

Now, plug in x for y. Here's what I mean...

y = 2x

y = 2 (-2)

y = -4

Hope this helps :)

Which graph shows the same end behavior as the graph of f(x) = 2x6 - 2x2 - 5?
aleksandrvk [35]

Step-by-step explanation:

End behavior of a polynomial function is the behavior of the graph of f(x) as x tends towards infinity in the positive or negative sense.

  Given function:

            f(x)  = 2x⁶   -    2x²   -  5

To find the end behavior of a function:

  • Find the degree of the function. it is the highest power of the variable.

  Here the highest power is 6

  • Find the value of the leading coefficient. It is the number before the variable with the highest power.

   Here it is  +2

We observe that the degree of the function is even

         Also the leading coefficient is positive.

For even degree and positive leading coefficient, the end behavior of a graph is:

x → ∞ , f(x) = +∞

x → -∞ , f(x) = +∞

The graph is similar to the attached image

Explain, with a test, why the two triangles in each figure are similar. Find the
frutty [35]

Answer:

x = 3, y = 6

Step-by-step explanation:

In the figure attached,

If ΔADE and ΔABC are similar triangles, their corresponding sides will be in the same ratio.

By this property,

\frac{AB}{AD}=\frac{AC}{AE}=\frac{BC}{DE}

\frac{AB}{AD}=\frac{AC}{AE}

\frac{AD+BD}{AD}=\frac{AE+EC}{AE}

\frac{3}{2}=\frac{x+1.5}{x}

3x = 2x + 3

3x - 2x = 3

x = 3

Similarly, \frac{AB}{AD}=\frac{BC}{DE}

\frac{3}{2}=\frac{y}{4}

y = \frac{3\times 4}{2}

y = 6

A group of scientists wants to investigate if they can predict the life expectancy
Brrunno [24]

Step-by-step explanation:

There is no question asked here, bit of course it is possible to predict the life expectancies of a lot of things. This takes patience, resistance, and persistence, because working on something that takes time without persistence would result in a painful waste of time.

To predict the life expectancy of an effect is to predict how long it is going to take before it goes extinct, or seize from existence.
