Step-by-step explanation:
You need to use parentheses around the numerator and denominator.

Answer:
Draw a dashed line to represent the graph of , and shade the portion above the line for positive values of x and y
Step-by-step explanation:
Let
x------> the number of nickels in the box
y------->the number of dimes in the box
we know that
so
Multiply by both sides
-----> inequality that represent the situation
The solution of the inequality is the shaded area above the dashed line for positive values of x and y
The equation of the dashed line is
therefore
the answer is
Draw a dashed line to represent the graph of , and shade the portion above the line for positive values of x and y
see the attached figure to better understand the problem
Answer: you have the right Idea a polygon has 5 sides or more
Step-by-step explanation:
That means f(x)=kx²
so
f(5)=75=5²k
solve for k
75=5²k
75=25k
divide by 25
3=k
f(x)=3x² is da equation
so
f(4)=3(4)²
f(4)=3(16)
f(4)=48
