Answer:
x=0
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
2x+5=−2x+5
Step 2: Add 2x to both sides.
2x+5+2x=−2x+5+2x
Step 3: Subtract 5 from both sides.
4x+5−5=5−5
4x=0
Step 4: Divide both sides by 4.
4x/4=0/4
X=0

Answer:
40,550
Step-by-step explanation:
40, 550 is the mod point
The answer is: the Y axis. :I
You reflect it, then you shift the shape 1 unit to the right. For example, Point U is at coordinates, -2, 2. Reflected across the Y axis, it's 2, 2. Then to get to the point that U' is at, you shift your reflected U to the right one unit. That gets you to coordinates 3, 2. Same thing goes for the other Points. Cx Hope this helped!!
Answer:
2097150
Step-by-step explanation:
<u>GIVEN :-</u>
- First term of G.P. = 6
- Forth term of G.P. = 384
<u>TO FIND :-</u>
- Sum of first 10 terms of the G.P.
<u>CONCEPT TO BE USED IN THIS QUESTION :-</u>
<em>Geometric Progression :-</em>
- It's a sequence in which the successive terms have same ratio.
- General form of a G.P. ⇒ a , ar , ar² , ar³ , ....... [where a = first term ; r = common ratio between successive terms]
- Sum of 'n' terms of a G.P. ⇒
.
<em>[NOTE :- </em>
can also be the<em> formula for "Sum of n terms of G.P." because if you put 'r' there (assuming r > 0) you'll get negative value in both the numerator & denominator from which the negative sign will get cancelled from the numerator & denominator. </em><em>YOU'LL BE GETTING THE SAME VALUE FROM BOTH THE FORMULAES.</em><em>]</em>
<u>SOLUTION :-</u>
Let the first term of the G.P. given in the question be 'a' and the common ratio between successive terms be 'r'.
⇒ a = 6
It's given that <u>forth term</u> is 384. So from "General form of G.P." , it can be stated that :-


Divide both the sides by 6.


![=> r = \sqrt[3]{64} = 4](https://tex.z-dn.net/?f=%3D%3E%20r%20%3D%20%5Csqrt%5B3%5D%7B64%7D%20%3D%204)
Sum of first 10 terms
