Answer:
Step-by-step explanation:
the solution to the system
= find the intersection of two lines
method( one )
solve the equations ( find(x , y) )
( 1 ) y = -x +3
( 2 ) y = x - 3
now , we let ( 1 ) + (2 )
we have 2y =0 ,thus y = 0
from ( 1 ) y = - x +3 , we know y = 0 ,
we rewrite ( 1 ) as 0 = -x + 3,thus x = 3
method( two)
see the intersection point of two lines
so the ans is B.(3 , 0)

The only set of elements that satisfied the equation 2x-1= -13 is {-6}.
<h3>What is a set?</h3>
A set is a combination of specific quantities in which the meaning of each variable must be the same.
For example {1,2,3,4,5,6...} is a set of natural numbers in which each variable is representing a natural number so the overall meaning is the same among all.
Another example could be a set of whole numbers like that.
Given the equation,
2x-1= -13
By taking -1 right-hand side
2x = -13 + 1 = -12
By dividing 2
x = -6
Hence "The only set of elements that satisfied the equation 2x-1= -13 is {-6}".

Answer:
-1723
Step-by-step explanation:
Evaluate 5 - t^3 where t = 12:
5 - t^3 = 5 - 12^3
12^3 = 12×12^2:
5 - 12×12^2
| 1 | 2
× | 1 | 2
| 2 | 4
1 | 2 | 0
1 | 4 | 4:
5 - 12×144

1 | 4 | 4 | 0
1 | 7 | 2 | 8:
5 - 1728
5 - 1728 = -(1728 - 5):
-(1728 - 5)

Answer: -1723
He was billed for 139 minutes
8 + 0.06x = 16.34
0.06x = 8.34
x = 139
