Answer:

(1,1), (-1,1)

Step-by-step explanation:

To reflect a point over the x-axis, simply make its x-value negative. So, we can take the sample point of (1,1), make its x-value negative, and get (-1,1).

For question 21 ... I need the answer and explain how I got the answer !!!

Answer:

27=3c-3(6-2c)

Open the brackets (multiply 6 and -2c by -3)

27=3c-18+6c

Add 3c and 6c

27=9c-18

Add 18 to both sides

45=9c

Divide by 9

c=5 (45/9)

now to check this just substitute c (5) into the equation

27=(3*5)-18+(6*5)

27=15-18+30

27=30-3

27=27

A) Work out the size of angle x. b) Give reason for your answer.

enot [183]

x=75°

We know that ∠EFG=∠ABF because they are corresponding angles.

We also know that ∠x+∠ABF=180, because angles along a straight line always equal 180:

x+105=180

x=75°
