Simplify the given expression.
(–3x2 – 9x + 17) – (15x2 + 20x – 4)
question 1 options: –18x2 – 29x + 13 –18x2 – 29x + 21 –18x2 – 11x + 21 –18x2 – 24x + 13

Option 2.

Step-by-step explanation:

If you simplify the equation, you get

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
