Answer:
11. True
12. True
13. False
14. False
15. True
16. False
17. x = 2.5
Step-by-step explanation:
With problems 11 to 16, You have to replace the h in the equations with 3 and see if the equation is true or not.
11. You can simplify the equation by solving the number in the parentheses first. So the problem would be 3(3 - 4) since you replace the h with a 3. (3 - 4) equals -1. So now the problem simplified is 3(-1) which is 3 x -1 which equals -3. Meaning that 3(h - 4) = -3 is true since h is 3.
With 17 and 18, you have to replace what number you think is x. A easy way of doing this is working in reverse.
17. So 4x has to equal 8 when 2 is taken away. To find this out, we add 2 to 8 which would equal 10. Then we divide 4 from 10 which equals 2.5. In order make sure that this is correct, we will put the equation back into normal formula. So 4x - 2 = 8 becomes (4 x 2.5) - 2 = 8. (4 x 2.5) equals 10, so 10 - 2 = 8.

Answer:
Raoul is correct
Step-by-step explanation:
Given
See attachment for missing details
Required
Determine if Raoul is correct or not
The initial value of both functions is when
<u>For function A (the graph)</u>
when
So, the initial value of the function A is 0
<u>For function B (the table)</u>
when
So, the initial value of the function B is 3
We can then conclude that Raoul is correct because 3 is greater than 0
