Solution:
From the given equations,
A function must pass the vertical line test but, equations with only x as the variable will not pass the vertical line test.
From the explanation above;
The graph above will pass the vertical line test.
Hence, the equation represents a function is
Answer:
This question requires us to change the subject of a formula. This can be achieved by following the order of operations in reverse. First, isolate the terms with our variable of interest, x:
ax - bx = z - y
Then, we take x out as it is being multiplied to both a and b:
x(a - b) = z - y
Dividing (a - b) on both sides, we get:
x = (z - y) / (a - b)
Thus, the answer is x= z-y/a-b
Step-by-step explanation:
Answer:b=5
Step-by-step explanation:
Answer:
If the diameter or radius of one circle is the same as another circle they are congruent.
Answer:
Age of ben = n years
Age of Chloe = 2n years
Age of Dan = (n - 5) years
Now,
Sum of ben, Chloe and Dan's age = t years
or, n +2n + n - 5 = t
or, 4n - 5 =t
This is the required formula
