Answer:
1: X= 8, 2: 2/5 or 0.4
Step-by-step explanation:
1: 2(2x + 1) + x = x + 2x + 18
5x + 2 = 3x + 18
2x = 16
x = 8
2: 2x + x + 2x = 10 + x
5x = 10 + x
4x = 10
x = 4/10
x = 2/5
x = 0.4
1. (x - h)² + (y - k)² = r²
(x - (-10)) + (y - 6)² = 4²
(x + 10)² + (y - 6)² = 16
The equation of the circle is (x + 10)² + (y - 6)² = 16.
2. The answer is A.
3. The equation of the parabola is y = ⁻⁵/₃₆x² - 1²/₃x - 2.
4. I don't know the answer to the problem.
Answer:
A to B = 2000 m/s
C to D = 30,000m/s
Step-by-step explanation:
A to B is 10secs and the distance is 200m so you multiply them and you get 2000m/s
C to D is 60secs and the distance is 500m so you multiply and you get 30,000m/s
Answer:
The answer is A) -9.272
Step-by-step explanation:
-5.872 + (-5.1)/1.5
= -5.872 - 3.4
= -9.272
