Answer:
a: 3
b: 12
c: 15
Step-by-step explanation:
12 + 15 = 27
There are 27 total. 
Since there are 27 in all, it's best if each small rectangle value is 3.

Answer:
   y = 3x -8
Step-by-step explanation:
We assume you want the tangent to the parabola y = x² -3x +1 at the given point. The slope is found using the derivative of the function at that point.
   y' = 2x -3
At x=3, the slope is ...
   y' = 2(3) -3 = 3
The equation of the line through point (3, 1) with a slope of 3 is ...
   y -1 = 3(x -3) . . . .  use the point-slope form of the equation for a line
   y = 3x -9 +1 . . . . . eliminate parentheses, add 1
   y = 3x -8

Answer:
The rule used to reflect Δ ABC to its image is Reflect over y = x ⇒ B
Step-by-step explanation:
- If the point (x, y) reflected across the x-axis
, then its image is (x, -y)
- If the point (x, y) reflected across the y-axis
, then its image is (-x, y)
- If the point (x, y) reflected across the line y = x
, then its image is (y, x)
- If the point (x, y) reflected across the line y = -x
, then its image is (-y, -x)
From the given figure
∵ The coordinates of point A are (-4.5, 6)
∵ The coordinates of point A' are (6, -4.5)
→ The coordinates are switched ⇒ 3rd rule
∴ Point A is reflected over the line y = x
∴ Δ ABC is reflected over the line y = x
∴ The rule used to reflect Δ ABC to its image is Reflect over y = x
<em>Note: Point B' on the graph should be C' and point C' should be B' (correct it)</em>
