What is the center of the circle with the equation x2 + y2 – 10x – 11 = 0 ?

1 answer:

4 0

Rearrange to standard form:-

x^2 - 10x + y^2 = 11
(x - 5)^2 - 25 + y^2 = 11
(x - 5)^2 + y^2 = 36

Center of circle = (5, 0) and radius = sqrt36 = 6

What must be true when solving a quadratic equation when using factoring?

Zigmanuir [339]

Answer:

Step-by-step explanation:

The function must be factorable.

For example, x^2 + x - 6= 0 factors to (x + 3)(x - 2) = 0 so the roots are -3 and 2.

x^2 + x - 7 = 0 will not factor so you need another method to solve this.

Evaluate the expression –0.4(3x – 2) + StartFraction 2 x plus 4 Over 3 EndFraction for x = 4

mixas84 [53]

Answer:

$-0.4(3x-2)+\frac{2x+4}{3}=0\ \textrm{for}\ x=4$

Step-by-step explanation:

Given:

The expression to evaluate is given as:

$-0.4(3x-2)+\frac{2x+4}{3}$

The value of 'x' is 4.

Plug in 4 for 'x' in the above expression and simplify. This gives,

$=-0.4(3(4)-2)+\frac{2(4)+4}{3}\\=-0.4(12-2)+\frac{8+4}{3}\\=-0.4(10)+\frac{12}{3}\\=-4+4\\=0$

Therefore, the value of the given expression for 'x' equal to 4 is 0.
