I think it’s asking for you to multiply (-3,7) and (7,-8)
So if it is it would be -21 times-56= 1,176 AB=1,176
Answer:
1/5
Step-by-step explanation:
In order to find the answer, we need to isolate the "n."
Get 5 to the other side by dividing both sides by 5
(n-1/10)= 1/2 ÷(5)
Multiply the 2 and the 5 of the equation.
(n-1/10)= 1/10
Next, move the fraction on the left side, to the right.
n= 2/10
Reduce.
n= 1/5
Step-by-step explanation:
y=-2x+1 so we say (-2x+1)
we flip the equation by saying
-2x+1 -1=y+-1
-2x=y-1
Divide both sides by -2
-2÷-1 = y-1÷-2
so x=-1÷2 y=+1÷2

Answer: the price of a senior citizen's ticket is $8.
the price of a child's ticket is $14
Step-by-step explanation:
Let x represent the price of a senior citizen's ticket.
Let y represent the price of a child's ticket.
On the first day of ticket sales, the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. It means that
3x + y = 38- - - - - - - - - - - -1
The school took in $52 on the second day by selling 3 senior citizen and 2 child tickets. It means that
3x + 2y = 52- - - - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- y = - 14
y = 14
Substituting y = 14 into equation 1, it becomes
3x + 14 = 38
3x = 38 - 14 = 24
x = 24/3
x = 8
