Answer:
(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}
Graph C represents the table of values
Step-by-step explanation:
To complete the table, substitute each value of x into the equation, 
, to find each corresponding y-value.
Thus:
✔️When x = 20:
✔️When x = 40:
✔️When x = 60:
✔️When x = 80:
✔️When x = 100:
✔️<em>The graph of that represents this table of values is graph C. See attachment.</em>
0.4% of 100 is .4 whoops i thought it was 0.4 as a decimal :P
A+b 5
------- = ---
2a-b 4
b 5
-------- = ---- => 9b = 5a+45 => b = (5a+45)/9
a+9 9
a+b 5
------- = --- => 4a+4b = 10a-5b
2a-b 4
9b = 6a
9(5a+45) =6a divide both sides by 3
3(5a+45) = 2a
15a +135 = 2a
13a = -135
a = -135/13 = -10,38
a= -10,38
9b=6a
3b=2a
3b = 2(-10,38)
3b = -20,76
b = -20,76/3
b = -6,92
hope this helped
Answer:B
Step-by-step explanation:
slope=(y-y0)/(x-x0)
Slope=(5-1)/(5-1)
Slope=4/4
Slope=1
Equation y=mx+c
m=slope
Y=
