The required inequality for the height of the building around the park should be y < 0.9x.
Given that,
A city has a building code that limits the height of buildings around the central park. The code says that all buildings must be less than 0.1x in height where x is the distance of the building from the center of the park and y is height in feet. Assume that the par center is located at 0.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
The height of all the buildings must be,
y < x - 0.1x
y < x(0.9)
y < 0.9x
Thus, the required inequality for the height of the building around the park should be y < 0.9x.

The coefficients in the expression are 3 and 7.
An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given expression is,
9 - 4 + 3b + 7a
So, from the given expression we can see that there are 4 terms, 2 constants and 2 coefficients.
The coefficient of b is 3,
and coefficient of a is 7.
So, there are 2 coefficients in the given expression.
Thus, the coefficients in the expression are 3 and 7.
