<h3>Answer: Choice A (upper left corner)</h3>

This shows a mirroring effect over the vertical y axis.

Choice D is a reflection but over the horizontal x axis.

Answer:

£2.38

Step-by-step explanation:

Write and solve an equation of ratios:

£1.40 2.5 kg

----------- = ------------

c 4.25 kg

Cross multiplying, we get:

(£1.40)(4.25 kg) = (2.5 kg*c), or

(£1.40)(4.25 kg)

c = -------------------------- = £2.38

Work out length of BC

Neporo4naja [7]

Answer:

assume $13 = z \\ 8 =x \\ bc = y$

by phytagorean theorem

${y}^{2} + {x}^{2} = z^{2}$

$bc = y = \sqrt{ {z}^{2} - {x}^{2} } = \sqrt{169 - 64} = \sqrt{105}$

6x + 4 - x = 2(x+1)

First combine like terms on the left side:

6x-x - 5x

So you have 5x+4 on the left side.

Then use the distributive property on the right side:

2(x+1) becomes 2x +2

Now you have 5x +4 = 2x +2

Subtract 4 from each side:

5x = 2x -2

Subtract 2x from each side:

3x = -2

Divide both sides by 3:

x = -2/3
