Answer:
f-1(x) = (x-8)/2
Step-by-step explanation:
f(x) = 2x+ 8
y = 2x + 8
replacing y and x
x = 2y + 8
2y = x- 8
y =( x-8)/2
f-1 (x) =( x-8)/2
Answer:
Yes
Step-by-step explanation:
The two rules for a proportional relationship are
- The line is straight (Check)
- The line goes though the origin (Check)
Because of that it is a proportional relationship.
Hope this helps :)
<span>the numbers of first 8 beads which are white are
1,5,9,13,17,21,25,29
think of it as an arithmetic progression here the first term will be 1 cause white was first bead then after 3 blue beads another white added soits position is fifth now the difference would come out as 5-1=4 so now position of next white bead could be predicted by nth term formula of an AP which a+(n-1)d here a is first term which in this case is one and d is difference which here is 4
So nth bead position is 1+(n-1)4</span>
Step-by-step explanation:
I'm not sure what you need help with, since what you have written down is correct. However, if you are looking for an explanation, here it is:
x + 5 < -2
To solve for x, we have to get x on one side by itself. Whatever you do to one side, you have to do to the other. Let's get rid of 5 to get x by itself.
x + 5 < -2 (Subtract 5 from both sides)
x < -7
Perfect! Basically what this is saying, is that all the values x can equal have to be less than -7. The sign < means less than.
For the signs < (less than) and > (greater than), we use an open circle.
For the signs ≤ (less than or equal to) and ≥ (greater than or equal to), we use a closed circle.
This is why we use an open circle for this example since x is LESS THAN -7.
The arrow is pointing to the left because these numbers are less than -7.
