Answer:
It is a horizontal line parallel to x axis
No, because it is not per second. You would have to simplify to per one second for it to be a unit rate. Hope it helps! :)
Answer:
(-3,4) would be the correct answer
Is that big ideas math? Also it is A.
Answer:
x=(2+ √-32)/2 or x=(2- √-32)/2
Step-by-step explanation:
x^2 - 2x = -9
x^2 - 2x + 9 =0
x = 2± (√(-2)^2 - 4*1*9)/2*1
Use the quadratic formula in the expression using a=1, b= -2, c=9
x = 2±√4-36 /2
x = 2+√4-36 or x = 2 - √4 - 32 /2
x = (2+√-32) /2 or x=( 2 - √-32 )/2
