Answer:
F(n) = (5n + 3) - (2n - 5)
F(4) = (5*4 + 3) - (2*4 - 5)
= 20 + 3 - 8 + 5
= 20
Hope this helps!
:)
20
Step-by-step explanation:
(5n+3)-(2n-5) =
= (5×4+3) - (2×4-5)
= (20+3) - (8-5)
= 23 - 3

2000
1600 is 100% - 20% = 80% of the original price.
So it is 4/5 of the original price.
So, the marked price is 1600 * 5/4 = 2000
5 , 10 , 15 , 20 , 25 , 30 , 35 , 40 , 45 , 50 , 55 , 60
6, 12, 18 , 24 , 30, 36 , 42 , 48, 54, 60
30 and 60
<em>Answer:</em>
<em>x ≅ 79.1</em>
<em>Step-by-step explanation:</em>
<em>10log(4x) = 25 </em>
<em>2log(4x) = 5 </em>
<em>log((4x)²) = 5 </em>
<em>(4x)² = 10⁵ </em>
<em>16x² = 100,000 </em>
<em>x² = 6,250 </em>
NOPE NOT AT ALL the line never goes through 0 on the x axis
