Step-by-step explanation: First, let's graph this down.
With all the points touching except (-2, -6) and (8, 18), it's safe to say that these are the coordinates that have to be removed. Also, just for an extra help, the linear line is 2x + 1 = y
Answer:A. -1.11x^2+ 3.74+ 10.64
Step-by-step explanation:
a. p. e. x. (just took the test)
Answer:
C
Step-by-step explanation:
∆=b^2-4a*c=1-4*3*(-10)=121>0 có 2x
x1=-b+sprt∆/2a=1+sprt121/2*3=2
x2=-b-sprt∆/2a=1-sprt121/2*3=-5/3
<span>y = mx + b ; where m=slope of the line.
You want the slope to go downhill from left to right, that would mean that m = (-)...
so the answer is D</span>
