(x+6)(x+9) = 0
x+6 = 0 or x+9 = 0
x = -6 x = -9
Answer is A. -6 and -9
H= -55t + 3000. Hope this helps!
Radii? Please explain what that means
Answer:
c,d
Step-by-step explanation:
factorise it
x + 4 = 0 ⇒ x1 = −4
x − 2 = 0 ⇒ x2 = 2
Answer:
(0,1)
Step-by-step explanation:
There are infinite number of (x,y) pairs in a line, so it should be easy to use any value for one of the coordinates (x or y) and find what the other coordinate should be. We can use a simple value that would make our solving easy, for example x = 0. We use this value to replace x in the equation of the line, and solve for y:

Therefore the pair (0,1) is a solution for the given equation.
