Step-by-step explanation:
(a)
let y = f(x), that is
5x + 3 = y
Rearrange making x the subject
Subtract 3 from both sides
5x = y - 3 ( divide both sides by 5 )
x = (y - 3) / 5, hence
(x) = (x - 3) / 5
(b)
(8) = (8 - 3) / 5 = 5/ 5 = 1

Step-by-step explanation:
To find the terms of the sequence substitute n = 1, 2, 3, 4, 10 into the rule.
n = 1 → 2(1)² = 2(1) = 2
n = 2 → 2(2)² = 2(4) = 8
n = 3 → 2(3)² = 2(9) = 18
n = 4 → 2(4)² = 2(16) = 32
n = 10 → 2(10)² = 2(100) = 200
The first 4 terms are 1, 8, 18, 32 and the 10 th term is 200
Answer:
The answer is c = 25.13 a =50.27
The answer to this question is extremely simple. Think of it this way. When you have 2 apples and you eat one how many do you have left? Well we can use the Pythagorean theorem, a^2 + b^2 = c^2, so 2^2 -1^2 = ?. Well how do you find exponents?
Good. What is the Pythagorean theorem? The Pythagorean theorem consists of a formula a^2+b^2=c^2 which is used to figure out the value of (mostly) the hypotenuse in a right triangle. The a and b are the 2 "non-hypotenuse" sides of the triangle (Opposite and Adjacent). Very simple. So you would have one apple remaining.
