This, you will have to use your calculator for, but I can still explain it.
First off, 9x10^-3 is equivalent to 0.009
Second: 2.4x10^-5 is equivalent to 0.000024
Parenthesis
Exponents
Multiple
Divide
Addition
Subtraction
PEMDAS is the order you go in always, if it's multiple or division, you do whichever one comes first, same with addition and subtracting, so left to right
FIRST: do 0.000024 / 0.0012 = 0.02
0.009 + 0.02 (answer above) = 0.29

What is the domain of the function y = -4x+1 if the range is -11
a_sh-v [17]

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.

On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.

In the case of the given equation:

y=-4x+1

The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:

x=-\frac{1}{4}(y-1)

If the range of the original function is the set given by the number {

Which ordered pair is not a solution of y = 2x + 1?
Dmitrij [34]

Answer:

(-1,1)

Step-by-step explanation:

All you have to do is plug it in the equation:

      (x,y)

For (-1,1)

1=2(-1)+1

Simplify:

1=-1 but you know that 1≠-1 so (-1,1) is not it

For (3,7)

7=2(3)+1

Simplify:

7=7

For (-3,-5)

-5=2(-3)+1

-5=-5

Simplify:

For (0,1)

1=2(0)+1

1=1
