Answer:
Step-by-step explanation:
Let her brother's age be x
Sarah age = 2x + 4
4000 divide by 160 to get the cost of each book
4000 / 160 = 25
So that's £25 per book, multiply that by two because they gave two away which is £50 so they lost £50
G(x) would involve a translation left 1 and up 1.
g(x) is written in vertex form, which is
g(x) = a(x-h)²+k, where (h, k) is the vertex. Since
g(x) = 4(x-8)²+9, the vertex is at (8, 9). Comparing this to the vertex of f(x), which is at (9, 8), it is left 1 and up 1.
Answer:
7, 11, 13, 17, 19
All of these numbers only have 1 and themselves as factors, and every other number can be written as a product of two or more primes, making the remaining number composite:
