Answer:

A) Dilated 150% then reflected across the x-axis

Step-by-step explanation:

By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.

We can then also see shape A has been reflected across the x-axis to give shape B.

B is two fifths of c 4a = 3c work out the ratio a:b:c give your answer in its simplest form where a, b and c are integers
Alex17521 [72]

Answer:

a : b : c = 12 : 10 : 15

Step-by-step explanation:

Given that: b = \frac{2}{5} of c

 i.e             b = \frac{2c}{5} ............... 1

          2c = 5b

So that;

          c = \frac{5b}{2} .................... 2

Also,    

          4a = 3c

           a = \frac{3c}{4} ................ 3

⇒          a = \frac{3}{4} × (\frac{5b}{2})

             a = \frac{15b}{8} ................. 4

           15b = 8a

           b = \frac{8a}{15} ................. 5

Comparing the derived equations:

From equations 2 and 3,

a:c = \frac{15b}{8}: \frac{5b}{2} = 4:5

From equations 1 and 2,

b:c = \frac{2c}{5} : \frac{5b}{2} = 2:3

But a common value of b = 15, gives;

a : c = 12 : 15 and b : c = 10 : 15  

Thus, a : b : c = 12 : 10 : 15

Solve for x and y in the system of equation<br>y=x²-4x<br>2x-y=2<br>I'll mark brainliest​
Goryan [66]

Step-by-step explanation:

y =  {x}^{2}  - 4x \\ y = x(x - 4) -  -  - (a) \\ 2x - y = 2 \\ y = 2x - 2 \\ y = 2(x - 2) -  -  - (b) \\ (a) = (b) :  \\ x(x - 4) = 2(x - 2) \\  {x}^{2}  - 4x = 2x - 2 \\  {x}^{2}  - 6x + 2 = 0 \\ x = 5.6 \:  \: and \:  \: 0.4 \\ y = 2(5.6 - 2) \:  \: and \:  \: 2(0.4 - 2) \\ y = 7.2 \:  \: and \:  \:  - 3.2
