Answer: -2.145
Step-by-step explanation:
(3.2+4x)+(18.25+6x)=
Simplifying
(3.2 + 4x) + (18.25 + 6x) = 0
Remove parenthesis around (3.2 + 4x)
3.2 + 4x + (18.25 + 6x) = 0
Remove parenthesis around (18.25 + 6x)
3.2 + 4x + 18.25 + 6x = 0
Reorder the terms:
3.2 + 18.25 + 4x + 6x = 0
Combine like terms: 3.2 + 18.25 = 21.45
21.45 + 4x + 6x = 0
Combine like terms: 4x + 6x = 10x
21.45 + 10x = 0
Solving
21.45 + 10x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-21.45' to each side of the equation.
21.45 + -21.45 + 10x = 0 + -21.45
Combine like terms: 21.45 + -21.45 = 0
0 + 10x = 0 + -21.45
10x = 0 + -21.45
Combine like terms: 0 + -21.45 = -21.45
10x = -21.45
Divide each side by '10'.
x = -2.145
Simplifying
x = -2.145

Answer: (x+7)^2 + (y+2)^2 = 4</h3>
===========================================================
Explanation:
The center is at (h,k) = (-7,-2)
h = -7
k = -2
The radius is r = 2 units
Plug these three pieces of info into the template below and simplify
(x-h)^2 + (y-k)^2 = r^2
(x-(-7))^2 + (y-(-2))^2 = (2)^2
(x+7)^2 + (y+2)^2 = 4
You can use a tool like Desmos or GeoGebra to confirm the answer.
Answer:
it is different because ax^2+bx+c with a ≠1 means that a is not equal to 1
and x^2+bx+c is different because x^2 is equal to 1x^2 but we dont usually write the 1 because it doesnt make any difference
