Answer:
D. -8
Step-by-step explanation:
0-4=-4
0-4=-4
-4 + -4 = -8
It’s 5 4321 idk either I just dumb
For this case, the first thing we are going to do is rewrite the expression.
We have then:
(18) / root (8)
(18) / root (2 * 4)
(18) / 2 * root (2)
(9) / root (2)
Thus, the values of a and b are:
a = 9
b = 2
Answer:
a = 9
b = 2
I would think that all but one point would be on the line. One way to approach this problem is to find the equation of the line based upon any two points chosen at random, and then determine whether or not the other points satisfy this equation. Next time, would you please enclose the coordinates of each point inside parentheses: (2.5,14), (2.25,12), and so on, to avoid confusion.
14-12
slope of line thru 1st 2 points is m = ---------------- = 2/0.25 = 8
2.50-2.25
What is the eqn of the line: y = mx + b becomes
14 = (8)(2.5) + b; find b:
14-20 = b = -6. Then, y = 8x - 6.
Now determine whether (12,1.25) lies on this line.
Is 1.25 = 8(12) - 6? Is 1.25 = 90? No. So, unless I've made arithmetic mistakes, (1.25, 5) does not lie on the line thru (2.5,14) and (2.25,12).
Why not work this problem out yourself using my approach as a guide?
