Answer:
Step-by-step explanation: first you have find a teacher in the building or the math teacher and tell them that you are using brainly to find the answers then they will give you a 0 so you dont have to fail
7s + 12 > 46 - 10s
Add 10s to both sides:
17s + 12 > 46
Subtract 12 to both sides:
17s > 34
Divide 17 to both sides:
s > 2
The inequality graphed would have an open dot on 2 and the arrow would be going to the right.

Step-by-step explanation:
When D is first reflected over line <em>l </em>, it looks like either a backwards or upside down D. When that D is reflected over line <em>m</em>, it will go back to looking like a normal D
Answer:
x = 9/25
y = 7/25
z = 4/25
Step-by-step explanation:
2x + y = 1 .......(1)
3y + z = 1 ........(2)
x + 4z = 1 ........(3)
Elimination 1 and 2
2x + y = 1 | ×3 |
3y + z = 1 | ×1 |
6x + 3y = 3
3y + z = 1
___________--
6x - z = 2 .............. (4)
Elimination 3 and 4
x + 4z = 1 | ×6 |
6x - z = 2 | ×1 |
6x + 24z = 6
6x - z = 2
___________--
25z = 4
z = 4/25
Elimination 3 and 4
x + 4z = 1 | ×1 |
6x - z = 2 | ×4 |
x + 4z = 1
24x - 4z = 8
___________+
25x = 9
x = 9/25
Subsitution 1
2x + y = 1
2(9/25) + y = 1
18/25 + y = 1
y = 1 - 18/25
y = 25/25 - 18/25
y = 7/25
Answer:
Parentheses
Step-by-step explanation:
These are used to single out a part of an equation, and most times you solve the equation in these before you solve anything else.
