Re-expressing data means making the facts more appropriate for evaluation by our methods.
We can not use a linear version until the connection among the 2 variables is linear. Often re-expression (transformation) can save the day, straightening bent relationships in order that we are able to suit and use a easy linear version.
• Two easy approaches to re-specific facts are with logarithms and reciprocals.
• Re-expressions may be visible in regular life— all and sundry does it.
We can re-specific gas performance as gallons in step with hundred miles (a reciprocal) and get rid of the bend in the authentic scatterplot.
Therefore, re-expressing data means making the facts more appropriate for evaluation by our methods.

The solution would be like
this for this specific problem:
a + 20 = 5/7 (3a - 20) <span>
a + 20 = (15a - 100)/7 </span><span>
Multiply both side by 7, </span><span>
7a + 140 = 15a - 100 </span><span>
8a = 240<span>
</span></span>a = 30
3a = 90
a + 20 = 50
3a - 20 = 70
<span>5/7 x 70 = 50</span>

It is the answer to the question
Answer:
A'(-4, 3)
Step-by-step explanation:
The given point is A(-2,4).
If this point is translated by the rule:
, then we can obtain the image of A(-2,4) by plugging x=-2 an y=4 into the rule.
The correct choice is A'(-4, 3)
Answer:
13.7 cm
Step-by-step explanation:
- there are 360° in a circle and in this image, we can see 90°+90°+66.4°=260.4
- since we know that 360°-260.4°=99.6°
- The angle measure of arc AD is 99.6°
Now that we covered that, we can use the arc length formula in order to find the length of arc AD.
- arc length = 2πr(Θ/360°)
- 2π(7.9)(99.6°/360°) = 13.7329
- rounded to the nearest tenth = 13.7
