Answer:
2x - 6 is 6 less than twice a number or 2(x-3) in factored form.
Hope this helps!
Mark me brainliest if I'm right :)
2A. Answer is 42.7. C squared minus B squared equals A squared. C^2 - B^2 = A^2. 48^2 - 22^2 = 42.66^2.
The equation of a circle with radius r and center at point (a, b) is given by
(x - a)^2 + (y - b)^2 = r^2
1.) For the circle given by x^2 + y^2 = 24
(x - 0)^2 + (y - 0)^2 = (√24)^2
Therefore, center = (0, 0) and radius = √24 = 4.9 units
3.) x^2 + y^2 -10x -2y = -10
x^2 - 10x + (-5)^2 + y^2 - 2y + (-1)^2 = -10 + (-5)^2 + (-1)^2
x^2 - 10x + 25 + y^2 - 2y + 1 = -10 + 25 + 1
(x - 5)^2 + (y - 1)^2 = 16
(x - 5)^2 + (y - 1)^2 = 4^2
Answer: Chad, Stephen, Jose and Mrquis
Step-by-step explanation:
We can change them to Percentage to make their ordering easier.
Mrquis ran 1/2 mile = 1/2 × 100 = 50%
Chad ran 7/8 mile = 7/8 × 100 = 87.5%
Jose ran 3/5 mile = 3/5 × 100 = 60%
Stephen ran 3/4 mile = 3/4 × 100 = 75%
Therefore, the ordering from the greatest to the least will be:
Chad, Stephen, Jose and Mrquis
