Given :
An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each.
Mrs. Tran spent a total of $93 on bandanas at this store.
To Find :
How many cotton bandanas did Mrs. Tran buy.
Solution :
Let, number of cotton and silk bandanas buys are x and y respectively.
So, 7x + 11y = 93
x = (93 - 11y)/ 7
Putting y = 1 , x = 82/7 ( not possible since x can only be positive integer )
Putting y = 4 , x = 7
Therefore, Mrs . Tran will buy 7 cotton bandanas.
Hence, this is the required solution.
Answer:
we conclude that:
Step-by-step explanation:
Given
f(x) = x+9
g(x) = x² + 7x – 14
To determine
g(f(-5)) = ?
First, we need to find f(-5)
f(x) = x+9
substitute x = -5
f(-5) = (-5)+9
f(-5) = -5+9
f(-5) = 4
so
g(f(-5)) = g(4)
Now, we need to find g(4)
g(x) = x² + 7x – 14
substitute x = 4
g(4) = (4)² + 7(4) - 14
g(4) = 16 + 28 - 14
g(4) = 30
i.e.
g(f(-5)) = g(4) = 30
Therefore, we conclude that:
