481*481= 231361
That in expanded form is
200000 + 30000 + 1000 + 300 + 60 + 1
Sorry if i am wrong I truely am
The answer is the first one if you dont believe me i calculated it <span />
Answer:
The following steps are needed:
1. Find the function of AB with A(-3,2) and B(7,6)
y(AB) = mx + b. Calculate m = (y₂-y₁)/(x₂-x₁) = (6-2)/(7+3) = 4/10 → 2/5
y(AB) = (2/5).x + b. Calculate b; 6 = (2/5).(7) + b and b = 16/5
y(AB) = (2/5).x +16/5
2. calculate the function y(CD) = mx + bWe know already m = -5/2, since CD is perpendicular to AB and hence the product of their slopes = -1
y(CD) = -(5/2).x + b
We also know that y(CD) passes in the middle of AB, then let's calculate the coordinate of C, the midpoint of AB:x=(x₁+x₂)/2 and y=(y₁+y₂)/2)x= (-3+7)/2 and y=(2+6)/2x= 2 and y=4y(CD) = (-5/2).x +b4 = (-5/2).(2)+b and b = 9y(CD) =(-5/2)x + 9
x intercept when y = 0 → 0= (-5/2)x +9 → x= 18/5So x intercept (18/5,0)
So the answer is at point B.
Let
x = cost of a ticket for a senior
y = cost of a ticket for an adult
z = cost of a ticket for a student.
The first student buys 2 senior, 1 adult, and 2 student tickets for $51.
Therefore
2x + y + 2z = 51 (1)
Th second student buys 1 adult and 5 student tickets for $5.
Therefore
y + 5z = 55 (2)
The third student buys 2 senior, 2 adult, and 7 student tickets for $75.
Therefore
2x + 2y + 7z = 75 (3)
Answer:
The system of equation for determining x, y, and z is
2x + y + 2z = 51
y + 5z = 55
2x + 2y + 7z = 75
Warnng: The system of equations does not have a solution.
