Answer:
Class A :
Class B :
Step-by-step explanation:
Class A :
Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.
Similarly let the amount of Water in the solution be x
As we are given that for Class A , The ratio of salt content to water content is 3 to 5
Hence
Multiplying both sides by x we get
Class B :
Let the amount of Salt in the solution be represented by y as, it is supposed to be the independent variable.
Similarly let the amount of Water in the solution be x
As we are given that for Class A , The ratio of salt content to water content is 2 to 4
Hence
multiplying both sides by x we get
Answer:
y = -|x +2| +4
Step-by-step explanation:
The parent function y=|x| is shifted to the left 2 units, so x is replaced by x+2. It is reflected across the x-axis, so is multiplied by -1: -|x+2|. It is shifted up 4 units, so has 4 added to it:
y = -|x+2| + 4
Answer: Complementary angles are pair angles with the sum of 90 degrees
Step-by-step explanation: When talking about complimentary angles, always remember that the angles appear in pairs. One angle is the complement of the other angle.
