Answer:
3,-1,-5 = -3
Step-by-step explanation:
The 3 odd numbers cannot be all negative ,the result would be less than -3
Multiplying by 0.1 is the same as dividing by 10, as 0.1 = 1/10
So, 37.4x 0.1 = 37.4/10 = 3.74
6/9 is the equivalent of 2/3, so what is 2/3 times 12? This will give you the answer. I hope this helps, have a nice day! :)
The solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7
<h3>How to determine the solution set of the equation?</h3>
The equation is given as:
x^2 + 2x - 48 = 0
A quadratic equation is represented as:
ax^2 + bx + c = 0
By comparing both equations, we have
a = 1, b = 2 and c = -48
The solution of the quadratic equation is then calculated using
x = (-b ± √(b^2 - 4ac))/2a
Substitute values for a, b and c in the above equation
x = (-2 ± √(2^2 - 4 * 1 * -48))/2 * 1
This gives
x = (-2 ± √196)/2
Evaluate the square root of 196
x = (-2 ± 14)/2
Divide through by 2
x = -1 ± 7
Hence, the solution set of the equation x^2 + 2x - 48 = 0 is x = -1 ± 7

I'm not sure about the answer myself, but here is how I think you would solve it.
First, you'd graph the circle. I recommend using a graphing calculator to do so.
Since the line is tangent and is meeting at the point (1,2) we can keep this in mind when creating our equation. From there, using what you know try to find a second point on the line.
From here it becomes normal algebra, use slope intercept form to create an equation.
I hope this helps!
