Answer:
15.5
Step-by-step explanation:
Answer:
i guess it's the second one, 16x2+9y2, since they are both raised to 2 and they are binomial
Answer:
3x+ 5 = 6
. Correct.
Step-by-step explanation:
Let x = the number.
The number tripled: 3x
Tripled and increased by : 3x + 5
Equals 6: 3x+ 5 = 6
Correct.
(-4)^2
A negative base raised to an even power gives us a positive so
4^2
4x4=16
Remark
The quick answer is C does not represent a function. It has two y values for x = 2. These two points are (2,1) and (2,3). That eliminates C. No x can have 2 y values and be called a function. A function can have many x vales for a single y and still be a function.
A has all different x values, so it could be classed as a function. There are no values where x has more than 1 y value.
B also has all different x values. It too is a function.
Answer
A and B are both functions. C is not.
