Answer:
Step-by-step explanation:
The equation being shown in the question is the absolute value of x. Absolute values when graphed show up as a V-shaped graph pointing upwards. This is because whatever value is passed as an input will output a positive, regardless of whether the input is positive or negative. Meaning that both 4 and -4 will output 4. That is why the graph is a V-shaped because the outputs repeat for both positive and negative inputs. In this case since the negative is outside the absolute value brackets the positive value given from the absolute value of the input will be turned into a negative. So this will cause the V-shape graph to be reflected across the x-axis. As seen in the attached picture below.
Answer:
The Coefficient for the x term must be twice the number of the square roots first and last terms.
Step-by-step explanation:
Hope my answer has helped you and if not i'm sorry.
We know that, 1 litre = 1000 ml
Then, 2 litres = 2000 ml
Hence, the required ratio of 1000 ml to 2000 ml be
= 1000 : 2000
= 1 : 2
