Given the center of a circle as ( 1, -1 ) and a point on the circle at (4 , 2). Write the equation of the circle. *

Andru [333]

Answer:

(x − 1)² + (y + 1)² = 18

Step-by-step explanation:

Equation of a circle is:

(x − h)² + (y − k)² = r²

where (h, k) is the center and r is the radius.

The center is (1, -1), so plugging that in:

(x − 1)² + (y + 1)² = r²

A point on the circle is (4, 2), so plugging that in:

(4 − 1)² + (2 + 1)² = r²

18 = r²

Therefore, the equation is:

(x − 1)² + (y + 1)² = 18

What is the slope of the line that passes through the points (-6, -8)and (-14, 4) ? Write your answer in simplest form.

Bingel [31]

Answer:

Slope = -3/2

Step-by-step explanation:

$Slope = \frac{Change -in -y}{Change- in -x}\\\\\\\\Slope = \frac{-8 - 4}{-6 - (-14)}$

$Slope = \frac{-12}{8}\\\\\\Slope = \frac{-3}{2}\\\\$

Which of the following is the correct graph of the solution to the inequality −18 > −5x + 2 ≥ −48?

monitta

Answer:

Option D. A number line with an open circle on 4 with shading to the right and a closed circle on 10 with shading to the left

Step-by-step explanation:

we have

$-18 > -5x+2 \geq -48$

Divide the compound inequality into two inequalities

$-5x+2 \geq -48$ -----> inequality A

$-5x \geq -48-2$

$-5x \geq -50$

Multiply by -1 both sides

$5x \leq 50$

Divide by 5 both sides

$x \leq 10$

The solution of inequality A is the interval ----> (-∞,10]

All real numbers less than or equal to 10

$-18 > -5x+2$ -----> inequality B

$-18-2 > -5x$

$-20 > -5x$

Multiply by -1 both sides

$20 < 5x$

Divide by 5 both sides

$4 < x$

Rewrite

$x > 4$

The solution of the inequality B is the interval ----> (4,∞)

All real numbers greater than 4

The solution of the compound inequality is

(-∞,10] ∩ (4,∞)= (4,10]

All real numbers greater than 4 and less than or equal to 10

A number line with an open circle on 4 with shading to the right and a closed circle on 10 with shading to the left
