Answer:
2
Step-by-step explanation:
aculalli i dont now the answer i only want a point ):
1. let x be the sold tickets for adults
3x be the sold tickets for students
x + 3x = 348
4x = 348
x= 87 tickets for adults
2. let x be the no. of books produced
41664 + 8.5x = 19x
41664 = 19x - 8.5x
41664 = 10.5x
x = 3968 books
You are given triangle RST with vertices R(-3,-1), S(-1,-1) and T(-4,-5).
1. Apply the rotation of 90° counterclockwise about the origin that has a rule:
(x,y)→(-y,x).
Then
- R(-3,-1)→R''(1,-3),
- S(-1,-1)→S''(1,-1),
- T(-4,-5)→T''(5,-4).
2. Second transformation is translation 1 unite up with a rule:
(x,y)→(x,y+1).
So
- R''(1,-3)→R'(1,-2);
- S''(1,-1)→S'(1,0);
- T''(5,-4)→T'(5,-3).
As you can see these points are exactly those from the task condition.
Answer: 1st transfomation is rotation of 90° counterclockwise about the origin and 2nd transformation is translation 1 unite up
x = 32°
The triangle has 2 equal sides and is therefore isosceles, thus the 2 base angles are also congruent.
The 2 base angles are of size x°
x = 
= 
= 32
Answer:
x=8/9
Step-by-step explanation:
5x+2(x-3)=-2(x-1)
5x+2x-6=-2x+2
7x-(-2x)-6=2
7x+2x=2+6
9x=8
x=8/9
