Hi there! The domain of a function refers to the values that can be validly input for x. In laymen's terms, domain is the x-values that exist on a graph of the equation.
If we were to plug in y=-2x+5 into a calculator that shows an infinite graph, we would see that the line of the equation would extend both ways infinitely! This means that all real numbers can be inputs for x, because for every x value that exists there is a corresponding y value.
This means that D. All real numbers, is your answer.
Hope it helps! :)
Answer:
p = 2
Step-by-step explanation:
17 - 2p = 2p + 5 + 2p
- 2p - 2p - 2p = 5 - 17
- 6p = - 12
p = -12 / -6
p = 2
8 = 2 x 2 x 2
11 = 11
12 = 2 x 2 x 3
LCM = 2 x 2 x 2 x 3 x 11 = 264
Answer:
210.25 or 210.3495409 depending on how your teacher does it
Step-by-step explanation:
Looking for circumference of the circle when it asks for perimeter
Formula for Circumference C = π x r <em>3 (cubed)</em>
The diameter is 10 so you take half of ten or 10 ÷ 2 = 5
5 x 5 x 5 = 125 (r squared equation)
125 x π = 392.6990817
Some classes ans stuff use 3.14 for pi so i'll show it that way too
125 x 3.14 = 392.5
(equation with π)
392.6990817 ÷ 2 = 196.3495409
196.3495409 + 14 = 210.3495409
(equation with 3.14)
392.5 ÷ 2 = 196.25
14 + 196.25 = 210.25
- x - 3( x - 2 ) = 3 ( 2 - x )
Multiply 3 with x - 2 on LHS and 3 with 2 - x on RHS
Now take -3x to LHS and change its symbol to +. And take 6 to RHS and change it to negative.
-3x and 3x will cancel out and also 6 and -6 will also get cancelled out.
