55?
500 - 280 = 220
220/4 = 55
500 - (4x55{his age}) = 280
Answer:
It has bumps, cracks and obstacles, but in the end, it gets you somewhere.
Step-by-step explanation:
Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.

Step (1) is incorrect. To divide by a number means to multiply by the reciprocal. In step (1) they did not convert the polynomial into its reciprocal.
