Answer:
4x-4
Step-by-step explanation:
x-10+3x+6=4x-4
Hope helps :3
Converting centimeters to the units of inches, we have to multiply a value with 2.54. From this, we can say that the relationship is linear. A linear relationship can be represented by an equation such as:
y = kx
For this case, k is 2.54. When the measurement in centimeters increase, its form in inches units as well increase.
If you would like to solve the above problem, you can do this using the following steps:
1.2 miles * 7 days = 1.2 * 7 = 8.4 miles ... Multiply 1.2 by 7.
2.4 miles * 7 days = 2.4 * 7 = 16.8 miles ... Multiply 2.4 by 7.
8.4 miles + 16.8 miles = 25.2 miles ... Add the two products.
The correct result would be A.
Answer: The proofs are given below.
Step-by-step explanation: We are given to prove that the following statements are tautologies using truth table :
(a) ¬r ∨ (¬r → p) b. ¬(p → q) → ¬q
We know that a statement is a TAUTOLOGY is its value is always TRUE.
(a) The truth table is as follows :
r p ¬r ¬r→p ¬r ∨ (¬r → p)
T T F T T
T F F T T
F T T T T
F F T F T
So, the statement (a) is a tautology.
(b) The truth table is as follows :
p q ¬q p→q ¬(p→q) ¬(p→q)→q
T T F T F T
T F T F T T
F T F T F T
F F T T F T
So, the statement (B) is a tautology.
Hence proved.
