Answer:
Explanation:
in each of the following substitute x with the variables in the bracket.
f(a) = 5x - 6
= 5a - 6
f(a+h) = 5 (a + h) - 6
= 5a + 5h - 6
f(a+h) - f(a) = (5a + 5h - 6) - (5a - 6)
= 5a + 5h - 6 - 5a + 6
= 5h
(as the 5a's and 6's cancel each other out.)
f(a+h) - f(a)/h = 5a + 5h - 6 - ((5a - 6)÷h)
take l.c.m
= <u>(5ah + 5h^2 - 6h - 5a + 6)</u>
h
Answer:
9
Step-by-step explanation:
Plug-in -3 into y=x^2 to get 9.
Answer:
d = 7.2
Step-by-step explanation:
To get d by itself, multiply both sides by 1.2.
d = 7.2
Heyo!
(a - 6)2
Multiply each term in the parenthesis by 2
2a - 6 × 2
Multiply the numbers
Your answer is
2a - 12
