You just multiply 50 times 10 which is 500. Or just add 50 and do that ten times.

PilotLPTM [1.2K]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Let's see if the sequence is Arithmetic or Geometric :}$

$\textsf{If the ratio between successive terms is }$ $\textsf{equal then, the terms are in GP}$

$\sf{ \dfrac{12}{-4} = -3}$

$\sf{ \dfrac{-36}{12} = -3}$

$\textsf{Since the common ratio is same, }$ $\textsf{we can infer that it's a geometric progression}$ $\textsf{with common ratio of -3}$

If x + 3y = 7 and x - 3y =7 , then find y<br><br> Please help me

telo118 [61]

Answer:

$x + 3y = 7 , x - 3y = 7 : y = , x = 7$

Step-by-step explanation:

$\left[\begin{array}{ccc}x + 3y = 7\\x - 3y = 7\end{array}\right]$

Isolate $x$ for $x + 3y = 7 : x = 7 - 3y$ :

Substitute $x = 7 - 3y$ :

$\begin{bmatrix}7-3y-3y=7\end{bmatrix}$

Isolate $y$ for $7 - 3y - 3y = 7 : y = 0$ :

For $x$ $=7-3y$

Substitute $y = 0$

$x=7-3 * 0$

$7 - 3 * 0 = 7$

$x = 7$

The solution to the system of equations are:

$y=0,\:x=7$

Hope I helped. If so, may I get brainliest and a thanks?

Thank you. Have a good day! =)
