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
Answer : 1 9/20
1st Step : Make common denominators
3/4 + 7/10 = 15/20 + 14/20
2nd Step : Add!
15/20 + 14/20 = 29/20
3rd Step : Simplify, make the fraction a mixed number
29/20 = 1 9/20
1 and 9/20 is your answer
Answer:
The Slope of AB: 5/1
The Slope of DC: -1/5
The Slope of BC: 2/3
The Slope of AD: 2/3
The quadrilateral is a trapezoid because BC and AD are parallel to each other while AB and DC are congruent.
