Answer:
0
Step-by-step explanation:
f(x) = -3x^2 + 6x
Let x=2
f(2) = -3*(2)^2 + 6(2)
=-3(4) +12
= -12+12
=0
Answer:
$24.50
Step-by-step explanation:
Since we know that 3 child tickets are $18.50 each, let's find out the total price of the child tickets.
18.50 x 3 = $55.50
Since we don't know the cost of each of the adult tickets, let's call it x.
Now let's make an equation!
55.50 + 2x = 104.50
Now we have to isolate x in order to find out the price of each adult ticket.
Let's subtract 55.50 on both sides
2x = 49
Now let's divide 2 on both sides.
x = $24.50
So the price of an adult ticket is $24.50
CHECK:
55.50 times 2 (24.50) = 104.50
{X l x < 1} and {X l x> 1}
Answer:
x= 16
y= -13
Step-by-step explanation:
x+y=3
x-3y=-29
Eliminate x and subtract the equations
2y=-26
y= -13
Plug in y for first or second equation
x=16

Answer:
- width 117 feet
- length 292 feet
Step-by-step explanation:
Let w represent the width of the field. Then w+175 is its length. The perimeter is ...
P = 2(L+W)
818 = 2((w+175) +w) . . . . . fill in given values
818 = 4w +350 . . . . . . . . . simplify
468 = 4w . . . . . . . . . subtract 350
117 = w . . . . . . . . divide by 4
w+175 = 292 . . . . find the corresponding length
The width of the field is 117 feet; the length is 292 feet.
