The formula for perimeter is
Side a x2 + side b x2
So just multiply 18 by two, and subtract it from 108
From the definition of a function, a function associates every element of the domain to a unique element in the codomain.
In other words, if two elements are equal in the domain, then their images should also be equal.
Since, x represents the number of cars, we consider the universal set as N, the set of all natural numbers.
Let x, y ∈ N and x = y
Then, 0.75x = 0.75y
⇒ f(x) = f(y)
Therefore, images are equal, whenever elements are equal.
Hence, the function f(x) = 0.75x is a function. Also, note that the domain of the function is the set of all natural numbers and the range is the set of real numbers.
Answer:
3 days
Step-by-step explanation:
company A would have the equation 50x+40 =y and company B would be 30x + 100 =y. we're tying to find the days that these cost the same so you would do 50x+40 = 30+100. When you isolate x you get 3
Answer:
let 'a' be the first term, 'd' be the common difference between all the terms of the sequence
Step-by-step explanation:
therefore, a = 3,
and, d = -9 -3
= -12
hence the 14th term would be,
=> a + 13d
=> 3 + 13( -12 )
=> 3 - 156
=> - 153
"She needs 1.5 cups of flour for 1 batch, but she wants to make 2.5 batches."
This means that she needs 7.5 cups of flour for 5 batches.
Hence, she needs 3.75 cups of flour for 2.5 batches.
