Rigid transformation is a transformation that does not change the measure of the side lengths and the angles.

  • Triangles 3, 5 and 7 are translations of triangle 1
  • Triangles 2, 4 and 6 are not translations of triangle 1

From the question (see attachment), we have the following observations

  • Triangles 3, 5 and 7 have the same orientation as triangle 1
  • Triangles 2, 4 and 6 are reflected versions of triangle 1

Translation and reflections are both rigid transformation.

However, when a shape is translated, the <em>resulting shape </em>must have the same orientation as the original shape.

This means that:

  • <em>Triangles 3, 5 and 7 are translations of triangle 1</em>
  • <em>Triangles 2, 4 and 6 are not translations of triangle 1</em>

A lady buys 20 trinkets at a yard sale.
Katen [24]

Answer:

Lady purchased 12 trinkets costing $0.30 each and 8 trinkets costing $0.65 each.

Step-by-step explanation:

A lady buys total number of trinkets = 20

Cost of each trinket is either $0.30 or $0.65.

Let the number of trinkets is x she purchased for $0.30 and y for $0.65

Then x + y = 20 --------(1)

Since she spends total amount = $8.80

Then the equation will be

0.30x + 0.65y = 8.80 ---------(2)

We replace x = (20 - y) from equation (1) to equation (2)

0.30(20 - y) + 0.65y = 8.80

6 - 0.30y + 0.65y = 8.80

0.35y + 6 = 8.80

0.35y = 8.80 - 6

0.35y = 2.80

y = \frac{2.80}{0.35}

y = 8

Now we put y = 8 in equation (1)

x + 8 = 20

x = 20 - 8

x = 12

Therefore, lady purchased 12 trinkets costing $0.30 each and 8 trinkets costing $0.65 each.

Which equation contains the points (-1,-8) and (3,4)
katrin [286]

Answer:

y = 3x –5

Step-by-step explanation:

for slope-intercept form, y = mx + b

find the slope, m

(-8 -4)/(-1-3) = m

-12/-4 =m

3 = m

Substitute for m and use either coordinate for y and x to calculate b

4 = 3(3) + b

4 = 9 + b. Subtract 9 from both sides

4 –9 = b

–5 = b. Rewrite the equation with the calculated values for m and b

y = 3x –5

Please help, will give brainlist
ladessa [460]

Answer:

x^{2}-2+\frac{20}{x+7}

Step-by-step explanation:

x + 7) x³ + 7x²- 2x + 6 ( x²- 2

        <u> x³ + 7x²</u>

                     -2x + 6

                     <u>-2x - 14</u>

                           +20

Therefore, we can write the expression in the remainder quotient form as,

x^{2}-2+\frac{20}{x+7}
