12-y=2x-5 in slope-intercept form

Gemiola [76]

Answer: y = -2x + 7

Step-by-step explanation:

Slope intercept form is the same as solving for y in the equation .

So solve for y and it will be in slope intercept form.

12 - y = 2x + 5 Subtract 12 from both sides

-12 -12

-y = 2x -7 Now divide both sides by -1

y = -2x + 7

Show that an exponential model fits the data. Then write a recrusive rule that models the data.

Brilliant_brown [7]

Answer:

Exponential function:

f(x) = abˣ

Use the given data to determine the function.

f(0) = ab⁰ = a*1 = a ⇒ a = 0.75

b = 2 as each of the f(n) is twice the previous one in series.

The model is:

f(n) = 0.75*2ⁿ

Recursive rule to reflect this is:

f(0) = 0.75
f(n) = 2*f(n-1)

Which system of equations can you use to find the roots of the equation 2x3 + 4x2 – x + 5 = –3x2 + 4x + 9?

Degger [83]

Answer:

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Step-by-step explanation:

The given equation is in the form $2x^3+4x^2-x+5=-3x^2+4x+9$

We have to evaluate the correct system of equations which can be used to find the roots of the equation.

We can find the root of the equation by plotting the graph of the equations. In order to graph, we can assume the left and right hand side of the given equation as two separate equations.

Therefore, we have

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Now, we plot the graph of these two equations in the same coordinate plane. The intersection point (s) would be the roots of the given equation.

Hence, the system of equation that we can use to find the root of the given equation is

$y=2x^3+4x^2-x+5$

$y=-3x^2+4x+9$

Last option is correct.
