Paralell has same slope
y=mx+b
m=slope
y=5x-1
when is the slope 5?
take the derivitive of 2e^x
f'(2e^x)=2f'(e^x)=2e^x
that is the slope
5=2e^x
divide both sides by 2
2.5=e^x
take the ln of both sides
ln2.5=x
when x=ln2.5 they are paralell
Answer: d≤69
Step-by-step explanation:
You would plug in all the values for d into the inequality
40(81) + 240 ≤ 3000
40(81) + 240 = 3000
3240+240=3000
3480=3000 false
40(75) + 240 ≤ 3000
40(75) + 240 = 3000
3000+240=3000
3240=3000 false
40(69) + 240 ≤ 3000
40(69) + 240 = 3000
2760+240=3000
3000=3000 true

Answer:
0.216 = 0.6³
Step-by-step explanation:
using the rule of logarithms
• 
x = n ⇔ x = 
0.216 = 3 ⇒ 0.216 = 
Answer:
244x²
Step-by-step explanation:
4x(64x - 9x + 6x)
256x² - 36x² + 24x²
280x² - 36x²
244x²
25 pens is better because if you see the cost of one it will be cheaper
