Answer:

(2x-7)(2x+7)

Step-by-step explanation:

Use the identity rule:

(a^2-b^2) = (a-b)(a+b)

To factor the given expression:

4x^2-49y^2

we can write this as:

(2x)^2-(7y)^2

Apply the identity rule we have;

(2x-7)(2x+7)

Therefore, the completely factor of the given expression is, (2x-7)(2x+7)

Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
Alla [95]

Considering the given equation of the circle, the true statements are given as follows:

  • The radius of the circle is of 3 units.
  • The center of the circle lies on the x-axis.
  • The circle has the same radius as the circle with equation x² + y² = 9.

<h3>What is the equation of a circle?</h3>

The equation of a circle of center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

The equation given is:

x2 + y² - 2x - 8 = 0.

Completing the squares, the equation is given as follows:

(x - 1)² + y² = 8 + 1

(x - 1)² + y² = 9.

Researching the problem on the internet, the true statements are:

  • The radius of the circle is of 3 units.
  • The center of the circle lies on the x-axis(y_0 = 0).
  • The circle has the same radius as the circle with equation x² + y² = 9.

I’ve been stumped on this question for a while (picture included)
julsineya [31]

Answer:

Since the question is indicating to use a graphing calculator, we can assume that we would be required to graph both of the equations.

Red = \sqrt{x+2}

Blue = 3x^2-4x-1

By graphing those equations, we can determine the solution(s)

The points where the graphs intersect would be your coordinates to derive your solution

Red = (1.864, 1.966)

Blue = (-0.427, 1.254)

The solutions would be the x-value of the ordered pair, in this case,

x = 1.864 AND x = -0.427
