Given:
y = x - 6 (1)
for the line
x² + y² = r² (2)
for the circle
When the line intercepts the circle, the x and y values will be equal.
Equate the values of y by substituting (1) into (2).
x² + (x - 6)² = r²
x² + x² - 12x + 36 = r²
2x² - 12x + 36 = r²
Answer: r² = 2x² - 12x + 36
Answer:
3x (x² + x + 1)
You could write any trinomial like this
Answer:
2
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
Simplifying the radicals
= 
= 
× = 4
= 
= 
× = 2
Thus
+ 2 - 2
= 4 + 2 - 4 ← collect like terms
= 2
0.9 seconds is the correct answer
Answer:
-5
Step-by-step explanation:
2 - 1 = 1
5 - 10 = -5
-5 divided by 1 = -5
