Pls me answer this , i need it answered really quickly , ill give brainiest to the correct person.

A rational number is written in the form p/q, where p and q are not integers and q is not equal to 0.

An irrational number can be written in decimal form and possibly no end. In simple words, an irrational number cannot be expressed as a fraction.

Rational Number is defined as the number which can be written in a ratio of two integers.  In rational numbers, both numerator and denominator are whole numbers, where the denominator is not equal to zero.

An irrational number is a number which cannot be expressed in a ratio of two integers.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
