Answer:
Bernie, Chrissy, Dina and Frank
Step-by-step explanation:
if all 73 tickers are sold, the theatre makes $438 so each ticket is worth $438/73
this equals to $6.00 for one ticket
this means that Bernie, Chrissy, Dina and Frank have enough money to see the movie
Answer: x = 3, y = 1, z = 2
<u>Step-by-step explanation:</u>
EQ 1: x - y - z = 0
EQ 3:<u> -x + 2y + z = 1 </u>
y = 1
EQ 2: 2x - 3y + 2z = 7 → 1(2x - 3y + 2z = 7) → 2x - 3y + 2z = 7
EQ 3: -x + 2y + z = 1 → -2( -x + 2y + z = 1) → <u>-2x + 4y + 2z = 2</u>
y + 4z = 9
y = 1 ⇒ 1 + 4z = 9
4z = 8
z = 2
Input y = 1 and z = 2 into one of the equations to solve for x:
EQ 1: x - y - z = 0
x - (1) - (2) = 0
x - 3 = 0
x = 3
Check:
EQ 2: 2x - 3y + 2z = 7
2(3) - 3(1) + 2(2) = 7
6 - 3 + 4 = 7
3 + 4 = 7
7 = 7 
Answer:
x = -2.44
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 10x from both sides:
x (-10x) = 22 + 10x (-10x)
x - 10x = 22
-9x = 22
Isolate the variable, x. Divide -9 from both sides:
(-9x)/-9 = (22)/-9
x = 22/-9
x = -(22/9)
x = -2.44 (repeating).
x = -2.44 (rounded) is your answer.

Explanation
Sorry but You gone have to higher the price for this, this is a big question.
Answer:
slope(m)=change in y/change in x
6=y-(-1)/x-4
6=y+1/x-4
6(x-4)=y+1
6x-24=y+1
6x-24-1=y
6x-25=y
hence this is the equation
