Solve for x:
x^2 + 4 x + 25 = 0 I ssume that's the notation.
Subtract 25 from both sides:
x^2 + 4 x = -25
Add 4 to both sides:
x^2 + 4 x + 4 = -21
Write the left hand side as a square:
(x + 2)^2 = -21
Take the square root of both sides:
x + 2 = i sqrt(21) or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
x = i sqrt(21) - 2 or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
Answer: x = i sqrt(21) - 2 or x = -i sqrt(21) - 2
The cost of the bottle alone costs $1.15, and the cork costs $0.05, you add them together and you get $1.20. That is how the bottle costs $1.20.
Answer:
The slope of the graph is: m = -6
The y-intercept of the graph is: b = 2
And the graph of the equation is shown below.
Step-by-step explanation:
We know that the slope-intercept form is
Where m is the slope and b is the y-intercept
Given the equation
comparing with the slope-intercept form
slope = m = -6
y-intercept = b = 2
Thus,
The slope of the graph is: m = -6
The y-intercept of the graph is: b = 2
And the graph of the equation is shown below.

Step-by-step explanation:
0.90 is closer to 1 and 0.12 is closer to 0; 0 is less than 1, so 0.90 is greater than 0.12 :)
