Chenoa starts with $250 in her saving account and each month she adds $15 in her saving account.
Therefore, we obtain a sequence as:
250, (250+15), (250+15+15),...
250, 265, 280,....
So, we get the first term (
) as 250.
Now , we can clearly observe that the first term is 250 and second term is obtained by adding 15 to the first term that is 265 and so on.
Similarly in an arithmetic progression, last term is 
and its previous term is 
.
Similarly, will be obtained by adding 15 to its previous term .
So, 
and =250.
Therefore, Option C is correct.
THE answer is D :))))))))))
Step-by-step explanation:
Consider x⅓ =a
then the following expression can be written as
a²+a-2
a²+2a-a-2
a(a+2)-1(a+2)
(a+2)(a-1)
a= -2 or, a= 1
Putting the value of a
x⅓ = -2 and, x⅓ =1
Hey there! I'm happy to help!
We have two values for y. Since y=y, this means that −2x + 4 and − 1/3x − 1 are equal as well, so we can put them in an equation and solve for x.
−2x + 4 = − 1/3x − 1
We subtract 4 from both sides.
-2x=-1/3x-5
We add 1/3 x to both sides.
-5/3x=-5
We divide both sides by -1 2/3.
x=3
Now, we plug this into one of the original equations to find y.
y=-2(3)+4
y=-6+4
y=-2
Therefore, the solution is (3,-2) or x=3 and y=-2.
I hope that this helps! Have a wonderful day! :D
