Answer:
f(9/2) = 17/2
Step-by-step explanation:
f(x) = 3x-5
let x=9/2
f(9/2) = 3*9/2 -5
f(9/2) = 27/2 - 5
get a common denominator
f(9/2) = 27/2 - 10/2
f(9/2) = 17/2
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.
C, positive linear association. It is positive because it moves upward on the graph (left to right) and it is linear because it is a nearly straight line.
15-3(4-2x)-7(x-8) = 15 - 12 + 6x -7x +56 = -x +59
15-3(4-2x)-7(x-8) = - x + 59
