A reflection across the x-axis has the rule:
(x,y)→(x,-y).
Then:
- A(-1,-1)→A'(-1,1),
- B(0,1)→B'(0,-1),
- C(4,2)→C'(4,-2),
- D(6,0)→D'(6,0),
- E(3,-3)→E'(3,3).
Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
1) Make them into equations.
0.05x + 20 = 0
0.07x + 10 = 0
2) Equate the two.
0.05x + 20 = 0.07x + 10
0.02x = 10
x = 500
Step-by-step explanation:
put some x values into the equation
i.e : -2, -1, 0 ,1 ,2
3/5 (-2) +2 = 4/5 (-2, 4/5)
3/5 (-1) +2 = 7/5 (-1, 7/5)
3/5 (0) +2 = 2 (0, 2)
3/5 (1) +2 = 2.6 (1, 2.6)
3/5 (2) +2= 3.2 (2, 3.2)
Then plot these on the graph as corodinates with the x values
Answer:
So the answer is 9
Step-by-step explanation
1 . The explanation is that you have to distrubte the parentheses 2.subtract 10 from both sides 3.simplify what you got after you 4.subtract 3 from both sides 5.simplify again 6.divide both sides of the equation by the same terms 7.simplify again and you get 9
Que, i think 1, 5 go into 1
