Answer:
Step-by-step explanation:
Given x = 2 and y = -3. Therefore, substitute x = 2 and y = -3 in the expression.
Multiplying the negative with negative equal positive. All negative numbers in the absolute will become positive.
Therefore the answer is 29.
Irrational numbers are numbers that do not repeat or terminate. π is a common example. 3+0.4=3.4, this number terminates. 0.444...+0.4=0.8444..., this number repeats.
Answer:
9 mph
Step-by-step explanation:
Let Kathryn can go x mph and Stephanie can go (x + 5) mph.
Therefore, Kathryn can go 25.2 miles in hours.
And Stephanie can go 25.2 miles in hours.
Given that
⇒
⇒ 126 = x² + 5x
⇒ x² + 5x - 126 = 0
⇒ (x + 14)(x - 9) = 0
⇒ x = -14 or x = 9
But x can not be negative, so x = 9 mph
Therefore, Kathryn can ride her bike at 9 mph. (Answer)
