Answer:
y = 45
Step-by-step explanation:
y = 9x
input = 5
y = 9(5)
9(5) = 45
y = 45
Answer:
Critical or Key numbers
the intervals which satisfy the inequality
b) fraction on the right-hand side.
Critical
that the denominator can not be equal to zero
Step-by-step explanation:
When solving a polynomial inequality by hand, the solutions of the associated equation are called the Critical or Key numbers. These numbers divide up the number line into regions that contain or do not contain the intervals which satisfy the inequality.
b. When solving a rational inequality by hand, the solutions of the associated equation as well as values that make the fraction on the right-hand side of the rational expression zero are called the Critical numbers. The restriction of a rational expression is that the denominator can not be equal to zero included (Undefined)included in the solution set.
Reduced by 20% means it is on sale for 80% of the original price ( 100% - 20% = 80%)
Multiply the original price by 80%
36 x 0.8 = 28.80
The sale price is £28.80
