Remember that a function composed with its inverse results in the placeholder
aka
(f o f⁻¹)(x)=x
so
(f o f⁻¹)(4)=4
Answer:
9p
Explanation:
4p + 5p are like terms since they have the same variable p
All you have to do is add the numbers
(4+5)p = 9p
Answer:
35
Step-by-step explanation:
j(j + 3) = 1330
Trial and error method:
j and j + 3 are pretty close to each other. Start by taking the square root of 1330.
sqrt(1330) = 36.5. One number is less than 36.5 and the other number if 3 more than that.
Since the product of j and j + 3 is 1330 which ends in 0, it is a multiply of 10 and 5.
Try 35 and 38. 35 * 38 = 1330
Answer: 35
Equation method:
j(j + 3) = 1330
j^2 + 3j - 1330 = 0
(j + 38)(j - 35) = 0
j = -38 or j = 35
