Ashley graphed the relationship in the tableWhat is the slope of the graph, and what does it represent?

Answer:

linne b

Step-by-step explanation:

you can see that on the x axis at point 3 you can go 4 up until the line B is met

Answer:

9 and 3.35 respectively

Step-by-step explanation:

Mean=Sum of data÷No. of data

=(3+5+6+9+11+12+17)÷7

=63÷7

=9

Standard Deviation=√{(sum of squares of data÷no. of data)-(sum of data÷no. of data)

=√(705÷7)-(63÷7)

=√100.71÷9

=√11.19

=3.35

Answer:

9 M

Step-by-step explanation:

a^2+b^2=c^2

12^2+b^2=15^2

144+b^2=225

-144         -144

b^2=81

b=sqrt of 81

b=9

Answer:

A'(1, 1); B'(3, 2); C'(1, 2)

Step-by-step explanation:

The original points are A(1,1 ), B(2, 3) and C(2, 1).

Reflecting the triangle across the x-axis will negate every y-coordinate; this maps

(1, 1)→(1, -1); (2, 3)→(2, -3); (2, 1)→(2, -1)

Rotating the figure 90° clockwise about the origin switches the x- and y-coordinates and negates the x-coordinate; this maps

(1, -1)→(-1 -1); (2, -3)→(-3, -2); (2, -1)→(-1, -2)

Reflecting across the line y=x will negate both the x- and y-coordinates; this maps

(-1, -1)→(1, 1); (-3, -2)→(3, 2); (-1, -2)→(1, 2)

Final answer:

To find the coordinates of ∆ABC after reflection across the x-axis, rotation by 90°, and reflection across y = x, we would apply these transformations to each point. Initially reflected across x-axis results in (x, -y), the 90° rotation gives (-y, x), and final reflection over y = x gives (x, -y). To find A′B′C′ we would need original coordinates, but general rule follows this pattern.

Explanation:

In this mathematics problem, we will find the coordinates for vertex A′, B′, and C′ of ∆A′B′C′. Given a triangle ∆ABC reflected across the x-axis, then rotated 90° clockwise about the origin, and finally reflected across the line y = x, we need the original coordinates of A, B, and C to find A′B′C′. However, if we take a generic point (x, y), we can assume the following:

1. The reflection about the x-axis would turn it into (x, -y).
2. The 90° clockwise rotation about the origin would give the new coordinates (-y, x).
3. Finally, the reflection over the line y = x would change (-y, x) to (x, -y).

Assuming these transformations, we can find the final coordinates for A′, B′, and C′.
