Answer:
this is Geometry right?
Step-by-step explanation:
19.
2568.75 - 2500 = 68.75;
( ? / 100 ) * 2500 = 68.75 ;
? * 25 = 68.75;
? = 68.75 ÷ 25
? = 2.75;
r = 2.75 %
Answer:
72-x=28 or 72-28=x
Step-by-step explanation:
The legs are 12 cm each, so the hypotenuse is√(144+144)=12√2☺☺☺☺

A linear function has 1 as the highest power of the variable.
A. f(x) = 2 - 7x
here, the highest power of the variable x is 1.
Hence it is a LINEAR function.
___________
B. f(x) = 2 + x + x^2
here, the highest power of the variable x is 2.
Hence it is NOT a linear function.
_______________

here, the highest power of the variable x is 1/2.
Hence it is NOT a linear function.
