Answer:
Step-by-step explanation:
f^-1(x)=x/2+3
<span>42=-2d+6
Here, to find d, you need to separate it on one side.
First, subtract 6 from both sides.
42-6 = -2d + 6 - 6
36 = -2d
Now divide both sides by -2.
36/-2 = -2/-2d
-18 = d
The answer to this problem is -18, or d = -18.</span>
<h3>You should pick:</h3>
The relationship is linear because each y-value is 5 more than the one before it.
<h3>Here's why I think so:</h3>
If we look at the relationship between the x values and the y values, we can tell that they both increase periodically. The x values increase by 1('s), while the y values increase by 5('s).
Think about it. If y starts off at 5 when x is at 0, and then goes to 10 by x becomes 1, and increases another 5 values when x increases by 1 (again), then we are witnessing a pattern. For every 1 x value, y increases by another 5 values. Such a repetitive relationship will clearly be shown with a line. Thus, the relationship is a linear one.
Since we know that the relationship of the table is linear, and that it is linear due to the fact that the y-value continuously increase by 5's without fail, the only answer that would make sense is the second one.
<em>Therefore, the answer is '</em><u><em>The relationship is </em></u><u><em>linear </em></u><u><em>because each y-value is 5 more than the one before it.</em></u><em>'</em>
(93+75+86+x)/4=81
93+75+86+x=324
The sum of the scores is 324. Now solve for x:
254+x=324
x=70
The answer is 70
Negation...means put " not " in both the hypothesis and conclusion
if a parallelogram DOES NOT have 4 congruent sides, then it is NOT a rhombus.
