The value of the expression at y = 2.5 is 6.25.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
y²
Substitute y = 2.5
= y²
= 2.5²
= 2.5 x 2.5
= 6.25
Thus,
The value is 6.25.

Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.
For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.
Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?
Select one:
A. f(x)=(34)^(x)+9
B. f(x)=0.45(1.9)^(x)
C. f(x)=(65)^(x)−6

Clare paid 50% more for her notebook than Priya paid for hers. Priya paid x for her notebook and Clare paid y dollars for hers. Select an equation that represents the relationship between y and x.
The equation y = 1.5x represents the relationship between y and x.
What is an equation?When two mathematical expressions are equivalent to one another in a system of variables, the system is called an equation.
Given that,
Amount paid by Priya for her notebook = x,
Amount paid by Clare for her notebook = y.
Since, Clare paid 50% more for her notebook than Priya.
The equation for the relationship between y and x can be written as,
y = 1.5 x
The required equation is y = 1.5x.
