First aircraft seats : x
second aircraft seats : y
third aircraft seats : z
<span>The first aircraft has 73 more seats than the second aircraft: x = y + 73
</span>
<span>The third aircraft has 57 fewer seats than the second aircraft: z = y - 57
</span>
<span>Their total number of seats is 427: x + y + z = 427
solve these three equations, you will get:
x = 210 seats
y = 137 seats
z = 80 seats
-------------------------
you can check your answer by:
x - y = 210 - 137 = 73 correct
and
z + 57 = 80 + 57 = 137 = y correct

Answer:
y(-4) = 5
y'(-4) = -7
Step-by-step explanation:
Hi!
Since the tangent line T and the curve y must coincide at x=-4
y(-4) = T(-4) = 5
On the other hand, the derivative of the curve evaluated at -4 y'(x=-4) must be the slope of the tangent line. Which inspecting the tangent line T(x) is -7
That is:
y'(-4) = -7
To the nearest thousand it would be 68000

the second i think i dont know for sure
