F(4) = 1/3 x 4(4)
=1/3 x 16
= 16/3
Answer:
D
Step-by-step explanation:
You have to have exactly the same thing underneath the radical. So for example in choice A you have sqrt(2) and sqrt(3) underneath the radical. They are not the same. Choice A is not the answer.
Choice B has the same problem sqrt(5) is not the same thing as sqrt(3) and choice B is not the answer.
Choice C has sqrt(5) and sqrt(6) as your choice. They are not the same. C is not correct.
D is the answer. Both choices have sqrt(7) as the radicals. They are both 7. They are the same.
Answer:
Step-by-step explanation:
To make d the subject of formula, we need to rearrange the equation such that we arrive at d= _____.
<em>Remove the fraction by multiplying (d +3) on both sides:</em>
<em>Expand</em><em>:</em>
<em>
</em>
<em>Bring</em><em> </em><em>all</em><em> </em><em>the</em><em> </em><em>d</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em> </em><em>and</em><em> </em><em>move</em><em> </em><em>the</em><em> </em><em>others</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em> </em><em>side</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>equation</em><em>:</em>
<em>Factorise</em><em> </em><em>d</em><em> </em><em>out</em><em>:</em>
<em>
</em>
<em>Divide</em><em> </em><em>by</em><em> </em><em>(</em><em>c</em><em> </em><em>+</em><em>1</em><em>)</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

Answer:
71th term is 141
Step-by-step explanation:
1 + (n - 1)*2 = 141 {Use distributive property}
1 + 2n - 2 = 141
2n - 1 = 141
2n = 141 + 1
2n = 142
n = 142/2
n = 71
Answer:
option 1 and 4
Step-by-step explanation:
The elimination method should be used when there are two variables with the same number in front of them but different signs.
In the first system, the first equation has -8y while the second one has 8y.
Both equations have an 8y with different signs therefore using the elimination method would be most logical.
In the fourth system, the first equation has a -4x while the second one has 4x.
Both equations have 4x with different signs therefore using the elimination method would be most logical
Reasons it can't be the other options :
In the second system, no variable has the same number before it so no variable can be eliminated unless you multiply the equations by a common multiple. The best method for this system would be graphing
In the third system y is defined by an expression therefore using the substitution method is the most logical approach.
