<span>7e^(×/3)=14
</span><span>e^(×/3)=14/7
</span>e^(×/3)=2
take ln of both sides;
lne^(×/3)=ln2
****You should be familiar that lne^x=x as ln is the inverse function of e and vice versa****
then;
x/3=ln2
x=3ln2
x approximately is equal to 2.1
X = low-energy lamp
y = high-energy lamp
1) 4x + 5y
2) 120= 4x + 5y
Answer:
x-int: (3, 0)
y-int: (0, 2)
Step-by-step explanation:
The x-int is found when y = 0. Set <em>y</em> to 0 to solve for the x-int.
The y-int is found when x = 0. Set <em>x</em> equal to 0 to solve for the y-int.
The answer is 9.857. This can be rounded.
