The function is discrete, as the fee is charged based on the hours
Answer:
- 12
Step-by-step explanation:
The sea level serves as a reference point and may be used to describe objacetsvir positions above or below it. Therefore, the sea level is regarded as a zero point or level. Hence, objects below are describes to be at a negative distance while those above are assigned the positive sign. Hence, for a position which is 12 km below sea level, then the object is said to be at a distance of - 12 km (below sea level takes the negative sign.)
You have to first make like terms

**you want the denominator to be 21
C = 10d+ 45 ? Hope this helps? Let me know if it’s right or not.
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
