Answer:
<em>Image: (-7,3)</em>
Step-by-step explanation:
<u>Reflections In The Coordinate Plane
</u>
<em>Reflect over the line y = x:
</em>
When reflecting a point across the line y = x, the x-coordinate, and y-coordinate change places.
Thus, the point (3,-7) maps to the point (-7,3) when reflected over y=x.
Answer:
x=80
Step-by-step explanation:
To find the average, we take the numbers, add them up. Then divide by the number of terms we added.
Let x= the unknown number
The average =90
Average = (138+40+102+x)/4
90 = (138+40+102+x)/4
Multiply by 4 on each side
90*4 =(138+40+102+x)/4 *4
360 = (138+40+102+x)
Combine like terms
360 = 280 +x
Subtract 280 from each side
360-280 = 280+x-280
80 =x
Hello there!
Your answer is D) not justifiable, because there is another variable to consider.
While Susie may gain weight during Christmas, the holiday is not magically making her gain weight. It is more likely all of those candy canes.
I hope I helped!
