Answer:

(a) ΔWZY ~ ΔWXZ ~ ΔZXY

Step-by-step explanation:

In order for the similarity statement to be correct, the corresponding sides need to be listed in the same order.

A: ΔWZY lists sides in order short leg (WZ), long leg (ZY).

ΔWXZ lists sides in order short leg (WX), long leg (XZ).

ΔZXY lists sides in order short leg (ZX), long leg (XY).

The first similarity statement is correct.

You can compare this to an incorrect one, the last one, for example.

ΔYZW lists sides in order long leg (YZ), short leg (ZW).

ΔXZW lists sides in order long leg (XZ), hypotenuse (ZW). Hypotenuse and short leg are not corresponding sides, so the similarity statement is incorrect.

Transformations can be thought of as functions that take the points from one object (the pre-image) to the corresponding points

sweet-ann [11.9K]

1. Translation of a units to the right and b units up has rule:

(x,y)→(x+a,y+b).

Then the function is

$T(x,y)=(x+a,y+b).$

2. Reflection across the y-axis acts in following way:

(x,y)→(-x,y).

Then the function is

$R_y(x,y)=(-x,y).$

3. Reflection across the x-axis acts in following way:

(x,y)→(x,-y).

Then the function is

$R_x(x,y)=(x,-y).$

4. Rotation of 90 degrees counterclockwise about the origin, point O acts bu the rule:

(x,y)→(-y,x).

Then the function is

$R_{O,90^{\circ}}(x,y)=(-y,x).$

5. Rotation of 180 degrees counterclockwise about the origin, point O acts bu the rule:

(x,y)→(-x,-y).

Then the function is

$R_{O,180^{\circ}}(x,y)=(-x,-y).$

6. Rotation of 270 degrees counterclockwise about the origin, point O acts bu the rule:

(x,y)→(y,-x).

Then the function is

$R_{O,270^{\circ}}(x,y)=(y,-x).$

Find the equation of the line passing through the points A (2,1) B (7,9)

Bezzdna [24]

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{9 - 1}{7 - 2} = \frac{8}{5} = 1\frac{3}{5}$
      y - y₁ = m(x - x₁)
       y - 1 = 1³/₅(x - 2) Point - Slope Form
       y - 1 = 1³/₅(x) - 1³/₅(2)
       y - 1 = 1³/₅x - 3¹/₅
       + 1    + 1
              y = 1³/₅x - 2¹/₅ Slope - Intercept Form
   -1³/₅x - y = 1³/₅x - 1³/₅x - 2¹/₅
      -1³/₅x - y = -2¹/₅
   -1(-1³/₅x - y) = -1(-2¹/₅)
-1(-1³/₅x) + 1(y) = 2¹/₅
   1³/₅x - y = 2¹/₅ Standard Form
       1³/₅(0) - y = 2¹/₅
      0 - y = 2¹/₅
      -y = 2¹/₅
      -1    -1
   y = -2¹/₅ Y - Intercept
   (x, y) = (0, -2¹/₅)

Bank A charges a monthly service fee of $5.00 and a per-check fee of $0.05,

Anna007 [38]

Answer:

2 + .05x = 1.5 +.1x

.5 = .05x

x =10 is number when costs are equal

So the 11th check makes Bank A cheaper

Answer:

Through ASA axiom.

Step-by-step explanation:

It should be by ASA axiom.

The ASA Theorem says: If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.
