Answer:
Equation: y = 65x
Randomly pick a x and y value and plug into above equation, if they don't equal then the x and y you've picked cannot be on this table.
Step-by-step explanation:
Pick any two points to find slope, let's got with (3, 195) and (4, 260):
slope m = (y₂- y₁) / (x₂ - x₁)
= (260 - 195) / (4 - 3)
= 65 / 1
m = 65
Find y-intercept by using m from above and another point from your table, let's go with (5, 325):
y = mx + b
325 = 65(5) + b
325 = 325 + b
b = 0
Use m and b to form equation of line:
y = mx + b
y = 65x + 0
y = 65x
Check:
point (3, 195): 195 = 65(3) ====> 195 = 195
point (4, 260): 260 = 65(4) ====> 260 = 260
point (5, 325): 325 = 65(5) ====> 325 = 325
point (6, 390): 390 = 65(6) ====> 390 = 390
Example of a point that doesn't belong on table:
point (8, 500): 500 = 65(8) ====> 500 ≠ 520
Answer:
Step-by-step explanation:
X = text message you send or receive
39.99 + 0.15x <span>≤ 45
0.15x </span><span>≤ 5.01
x </span><span>≤ 33
the maximum </span>text message you send or receive is 33
39.99 + 0.15(33) = 44.94
Answer:
Step-by-step explanation:
You haven't attached any graphs but as there area 3 distinct roots the graph will have 2 loops.
Also the end behaviour will be rising from the left negative values of f(x) and at the right it will rise to positive f(x).
