Answer:
The solution for given system of equation is: 
and ordered pair is: 
So, (1,3) is not solution to the given system of equations.
Step-by-step explanation:
we can solve the system of equations to find the value of x and y and then verify if (1,3) is a solution or not.
The system of equation given is:
Solving:
Let:
Put value of y from equation 2 into equation 1
Now, put value of x in equation 2 to find value of y
So, the solution for given system of equation is: and ordered pair is:
So, (1,3) is not solution to the given system of equations.
Graph?
well
for
|a|>b solve
a>b and a<-b
|4w+1>11
solve
4w+1>11 and 4w+1<-11
minus 1 both sides
4w>10 and 4w<-12
divide both sides by 4
w>5/2 and w<-3

not including
2.
union means include all common to both
so
2. 1,2,3,4,6,8,9
3. 1,2,3,4,5,7,10
4. interseciton so only ones common to both, so 4
5. null set (empty)
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (5, 3)
m = 
= 
= 0
Answer:
a. 7(2g + 20t –3)
b. 14g + 140t – 21
Step-by-step explanation:
a. The first expression 7(2g + 20t – 3)
Stacey and her six friends implies that we have 7 members in the group.
Therefore, the expression above implies that each member of the group has to pay for two rounds of golf and 20 tokens will be discounted $3.00.
The expression (2g + 20t –3) represents the quantity of cost of each friend and this is multiplied by 7 to obtain this first expression, i.e. 7(2g + 20t –3).
b. The second expression 14g + 140t – 21
The simple interpretation of this expression us that deducting $21 from the to total bill which is 14 games of golf plus 140 tokens is equal to the total amount this group spent.
Therefore, this second expression is obtained by simply opening the bracket in the first expression by multiplying 7 by each of the what is in the bracket.
