Which problem do u need help with I can help u with all. All of them are scientific notation so it's easy and I will tell u an easy way to solve it
The answer to this question would be C, 9. The reason for is cause you remove the parentheses then add the numbers 1.2 + 7.8=9.
You can't round to the nearest whole number because you got to stay the same
Answer:
HERE IS YOUR ANSWER IN PICTURE.
Answer:
Option (1) ; y = 7x
Step-by-step explanation:
(1) reads y = 7x, a line with slope 7, therefore the rate of change in this is 7
(2) says that y increases 12 units every time that x increases 4 Then the rate of change is: (increase in y / increase in x = 12/4 =3
(3) shows a table from which we can see that an increase of y in 8 corresponds to an increase of x in 2: rate of change = (8 - 0) , (2 - 0) = 4
(4) shos a line with slope (rate of change) given by: (12 - 0) / (2 - 0) = 12/2 = 6
Therefore, the greatest rate of change is shown by the first expression
y = 7 x
