Answer:
If ƒ(x ) = 3x + 1, then ƒ(a + h ) - ƒ(a ) = 3h
Step-by-step explanation:
Given ƒ(x ) = 3x + 1, then to calculate ƒ(a + h ) - ƒ(a ), you need to replace "x" for (a + h) and a, respectively.
So...
f(a +h) = 3(a + h) + 1
and
f(a) = 3a + 1
Then
ƒ(a + h ) - ƒ(a ) = 3 (a + h) + 1 - [3a +1] = 3a + 3h + 1 - 3a - 1 = 3h.
So, ƒ(a + h ) - ƒ(a ) = 3h
3x² -x+4=0
We can use quadratic formula
a=3, b= -1, c=4
Percent decrease: (original number - new number) / original number....x 100
percent decrease : (6.50 - 4.25) / 6.50....x 100
2.25 / 6.50 = 0.346....x 100 = 34.6% <==
Answer:
x =66
Step-by-step explanation:
The sum of the opposite interior angles is equal to the exterior angle
32+x = 98
Subtract 32 from each side
32+x-32 = 98-32
x =66
