Answer: The next step will be 2x - 1 = 9
Step-by-step explanation:
4x -1 = 2x + 9
-2x -2x
2x -1 = 9
+1 +1
2x= 10
x= 5
For this case we have the following vertices:
D = (- 1, -1)
E = (1, -1)
F = (- 1, -6)
Then, the vertices after the transformation are:
D '= (- 1, 1)
E '= (1,1)
F '= (- 1,6)
The x coordinate remains the same
The y coordinate change sign.
Therefore, the transformation is:
Reflection on the x axis.
Answer:
Reflection on the x axis.

Answer:
2.25 or 2 1/4 pounds
Step-by-step explanation:
We need to find the weight of the food and water. To do this, find the difference between his backpack before the food and water and after. His backpack without the food is 7 3/4 pounds, and his backpack after is 11 3/4 pounds.
11 3/4 - 7 3/4
4
The food and water together weigh 4 pounds. We know the water weighs 1 3/4 pounds, so we can subtract it from the total to find what the food weighs.
4- 1 3/4
2 1/4
As a decimal: 2.25
The food weighs 2 1/4 or 2.25 pounds
