Does anyone know what irrational numbers are and if so can you explain it to me???
Romashka [77]

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. <u>Instead, the numbers in the decimal would go on forever, without repeating.  Ex) .7583947262.........    It doesn't repeat and goes on forever</u>

Does anyone know what f(x)=-5x-1 when f(-7) i need help with this please.
vodomira [7]

Answer:

f(-7) = 34

Step-by-step explanation:

If f(x) = -5x - 1, then . . .

f(x) = -5x - 1

f(-7) = -5(-7) - 1

       = 35 - 1

       = 34

. . . because in f(-7), the (-7) is the x-value you're supposed to use to find the value of the function.
