Answer:
Try asking your teacher if you don't understand it that well.
Step-by-step explanation:
Answer:
x< -4
Step-by-step explanation:
It represents the value of (x-4) when x=3
so the answer is A
Answer:
(x + 6)² + (y + 8)² = 100
Step-by-step explanation:
<u>Equation of circle:</u>
(x – h)² + (y – k)² = r²
Step 1: Find the radius
Draw a circle and mark the centre at (-6,-8).
Mark a point at (0,0)
Take a compass and draw a circle.
Draw a vertical line from centre of the circle to the end and find the radius.
The radius is from -8 till 2 which means 10.
<u>Step 2: Find the equation of the circle</u>
(x – h)² + (y – k)² = r²
(x -(-6))² + (y – (-8))² = 10²
(x + 6)² + (y + 8)² = 100
Therefore, the last option is correct.
