Answer:

The required expression is 7n²+89n+60

Step-by-step explanation

To get the expression, we will multiply the two linear expression by opening the bracket to give a quadratic equation.

(n + 12) x (5+7n)

We will use the variable and the constant of n + 12 to multiply that of 5+7n to give;

(n + 12)(5+7n) = 5n + 7n² + 60 + 84n

Rearranging the equation gotten we will have;

7n²+84n+5n+60

= 7n²+89n+60 which is the required quadratic expression.

Which graph represents the solution to the given system? y = -2x + 5 and y = 3x - 2

sasho [114]

To find the X value of the solution, you would set the two equations equal to each other bu substitution:
if y = -2x + 5 and y = 3x - 2,
-2x + 5 must be equal to 3x - 2
solve for x... you should get 7/5

then, plug that into one of the original equations as X and you would get the Y value, 11/5

This point, (7/5,11/5) is where the two lines cross

Show that the equation x^4/2021 − 2021x^2 − x − 3 = 0 has at least two real roots.

andreev551 [17]

The roots of an equation are simply the x-intercepts of the equation.

See below for the proof that $\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}$ has at least two real roots

The equation is given as: $\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}$

There are several ways to show that an equation has real roots, one of these ways is by using graphs.

See attachment for the graph of $\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}$

Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)

From the attached graph, we can see that $\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}$ crosses the x-axis at approximately -2000 and 2000 between the domain -2500 and 2500

This means that $\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}$ has at least two real roots
