Answer:
The total refund that the museum owes the 11:00am group is $28.50
Step-by-step explanation:
$12.25*38 = $465.50
$11.50*38 = $437
Subtract: $465.50 - $437 = $28.50
Answer:
30x - 48
Step-by-step explanation:
6 (5x) = 30x
6 (-8) = -48
30x - 48
x = [-3 +/- √(3^2 - 4*1*2) ] / 2
= [- 3 + √( 1)] / 2 , [- 3 - √( 1)] / 2
= -2/2 , -4/2
= [-1, -2} answer
Answer:
2/3
Step-by-step explanation:
6x + 4y = 72
-6x -6x
4y = 72 - 6x
/4 /4
y = 18 - 6/4x
y = -6/4x + 18
perpidicular slope is the opposite reciprical of the original line:
-6/4 is the slope of the line above.
4/6 or 2/3 would be the desired slope
check:
the two slopes mutplied would equal -1
-6/4 x 2/3 = -12/12 = -1
