Answer:
The conclusion is invalid.
The required diagram is shown below:
Step-by-step explanation:
Consider the provided statement.
People who use aluminum siding are satisfied Therefore, if you don't use our aluminum siding, you won't be satisfied.
From the above statement we can concluded that those use aluminum siding are definitely satisfied but it may be possible that some people don't use aluminum siding but they still satisfied.
Therefore, the conclusion is invalid.
The required diagram is shown below:
30 & 150. 150 is five times 30, and 150+30=180
(2-7i)(9+5i)
18+10i-81i-35i^2
The answer is 35i^2 - 71i +18
Answer:
(1, - 6 )
Step-by-step explanation:
Given the 2 equations
y = x - 7 → (1)
y = - 4x - 2 → (2)
Substitute y = x - 7 into (2)
x - 7 = - 4x - 2 ( add 4x to both sides )
5x - 7 = - 2 ( add 7 to both sides )
5x = 5 ( divide both sides by 5 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 into (1)
y = 1 - 7 = - 6
Solution is (1, - 6 )
