Alright, so we start off my subtracting 4a from both sides, separating the x and getting 10-4a=2x. Next, we divide both sides by 2, getting that 5-2a=X
Answer:
(- 4, 3 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x ) , then
(3, 4 ) → (- 4, 3 )
The roots are-4 and 7y=x² - 3x - 28<span>The roots are
-9 and 2</span>x² = 18 - 7xThe roots are-4,and 2y = x² + 2x -8The roots are-8 and 10x² - 2x - 6 = 74<span>The roots are
-15 and-1</span>x² + 15 = - 16xThe roots are-5 and 9y=x² - 4x - 45<span>The roots are
4 and 14</span>x² - x + 56 = 17x<span>The roots are
2 and 27</span>x² - 29x = - 54
To find n-therm of a geometric sequence, we are going to use the formula

where:

is the term we are looking for

is the first term

is the ratio

is the position of the number in the sequence
From the question we now that

,

, and

. Lets replace those values into our formula to get:



We can conclude that in our geometric sequence

; therefore, the answer is
A.
It looks right to me. Maybe try to switch the S and R but keep the ray symbol over the letters.
