Answer:

B. Exactly One Solution

Step-by-step explanation:

Given:

7(y+3)=5y+8

Expand the brackets:

\implies 7y + 21 = 5y + 8

Subtract 21 from both sides:

\implies 7y + 21-21 = 5y + 8-21

\implies 7y=5y-13

Subtract 5y from both sides:

\implies 7y-5y=5y-13-5y

\implies 2y=-13

Divide both sides by 2:

\implies \dfrac{2y}{2}=\dfrac{-13}{2}

\implies y=-\dfrac{13}{2}

Therefore, the equation has <u>exactly one solution.</u>

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15.
Naya [18.7K]
It's a geometric sequence.

4,-12,36,... \\ \\&#10;a_1=4 \\&#10;r=\frac{a_2}{a_1}=\frac{-12}{4}=-3 \\ \\&#10;a_n=a_1 \times r^{n-1} \\&#10;a_n=4 \times (-3)^{n-1} \\&#10;a_n=4 \times (-3)^{-1} \times (-3)^n \\&#10;a_n=4 \times (-\frac{1}{3}) \times (-3)^n \\&#10;a_n=-\frac{4}{3}(-3)^n

It's the sum for term 4 through term 15.

 \boxed{ \sum\limits_{n=4}^{15} (\frac{4}{3}(-3)^n)}
