Answer:
y = 2x+4
Step-by-step explanation:
From the graph, we can tell that slope is 2 because if we go up 2 units up from (0,4) which is point Q and then go right 1 unit, the slope is 2. The y intercept is (0,4)
y = mx + b
m --> slope
b --> y-intercept
y = 2x+4
let "one number" = x, and "another" = y
x = 4y + 4
(x + y) - 4 = 28
Plug in 4y + 4 for x
4y + 4 + y - 4 = 28
Simplify. Combine like terms
5y = 28
Isolate the y. Divide 5 from both sides
y = 28/5
y = 5.6
Plug in 28/5 for y.
x = 4y + 4
x = 4(28/5) + 4
Simplify
x = 22.4 + 4
x = 26.4
x = 26.4, y = 5.6
hope this helps

<span>Answer: 11,390 tickets in its 10th year</span>
We are given with the equation <span>f(x) = ax3 + bx2 + cx + d
Substituting, (3,11)
</span><span>11= 27a + 9b + 3c + d
</span><span>@(5, 9)
</span><span>9 = 125 a + 25 b + 5c + d
@</span><span>(4, 10)
</span><span>10 = 64 a + 16 b + 4c + d
@inflection point, second derivative is equal to zero
</span><span>f'(x) = 3ax2 + 2bx + c
</span>f''(x) = 6ax + 2b = 0
when x is 4, 24 a + 2b = 0 or 12a + b = 0.
There are 4 equations, 4 unknowns: answer is
