Answer:
C. m ≥ 9
Step-by-step explanation:
7m -2 ≥ 61
7m ≥ 61+2
7m ≥ 63
m ≥ 63/7
m ≥ 9
Answer:
x = 7
y = 2
Step-by-step explanation:
x + y = 9 but y = x - 5
x + (x - 5) = 9
2x - 5 + 5 = 9 + 5
2x/2 = 14/2
x = 7
y = x - 5
y = (7) - 5
y = 2
I highly recommend using the unit circle; the answer is 1/2.
The last one D because it is rational
I think you meant to write
(2 × 10⁶) × 0.00009
First, convert 0.00009 to scientific notation:
0.00009 = 9 × 10 ⁻⁵
Then
(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)
… = (2 × 9) × (10⁶ × 10 ⁻⁵)
… = 18 × 10¹
… = 1.8 × 10²
