Answer:

  1. reflection across the origin
  2. rotation 180° about the origin
  3. reflection across the x-axis, and translation right 6 units

Step-by-step explanation:

The figure and its image are symmetrical about the origin, so the following three transformations are equivalent:

  1. reflection across the origin

  2. rotation 180° about the origin

  3. reflection across both x- and y-axes, in either order

__

The figure itself has left-right symmetry, so only one reflection is necessary to map the figure to its image: reflection across a horizontal line. Following that reflection, the image can be put into place by an appropriate translation. One such pair of transformations is ...

  4. reflection across the x-axis and translation 6 units right, in either order

What is the slope of the line containing (-3, 5) and (6, -1)?
mario62 [17]

Answer:

-2/3

Step-by-step explanation:

The slope of a line can be represented as \frac{y_{2} -y_{1} }{x_{2}- x_{1} } where (x1, y1) and (x2, y2) are points on the line. We can substitute the points given, (-3, 5) and (6, -1), to calculate the slope:

\frac{-1-5}{6-(-3)} =\frac{-6}{6+3} =\frac{-6}{9} =-\frac{2}{3}

PLEASEE HELP I'LL GIVE BRAINLIEST.
just olya [345]

Answer:

No, Elias doesn't have enough quantity of each ingredient to make 45 mince pies.

Step-by-step explanation:

For making 18 Mince Pies Elias needs

200g Butter

225g flour

150g sugar

250g Mincemeat

1 egg

Inorder to make 45 mince pie's he's gonna need 45/18=2.5 times the ingredients he needs to make 18 Mince Pies.

As he doesn't have enough Mincemeat (has only 600g but needs 250*2.5=625g of mincemeat)

As he is short of 25g of Mincemeat, he is unable to make 45 Mincepies.
