Answer:
<em>n = 6 </em>
Step-by-step explanation:
2.3 × = (1 × 10³)(2.3 × )
(1 × 10³)(2.3 × ) = (1)(2.3) × (10³)( ) = 2.3 ×
2.3 × = 2.3 × ⇒ 3 + n = 9 ⇒ <em>n = 6</em>
Y - y₁ = m(x - x₁)
y - 5 = -8(x - 2)
y - 5 = -8(x) + 8(2)
y - 5 = -8x + 16
<u> + 5 + 5</u>
y = -8x + 21
The cost for 9 lbs would be 63 dollars
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>q is independent variable, we need to solve it for s:</u>
- 6q = 3s - 9
- 3s = 6q + 9
- s = 2q + 3
<u>Correct choice is </u>
