I don’t know what’s being asked in particular yet:
y=-2x+1
y-intercept= 1
x-intercept= 1/2
graphing: starting at the y axis at +1 , go down 2 units and then one unit to the right.

y=-2x-3
y-intercept= -3
x-intercept= -3/2
graphing: starting at the y axis at -3 , go down -2 units and one unit to the right.

How do we find 4and1/4 hours after 11:20pm?
tigry1 [53]

there are 60 minutes in 1 hour, so 1/4 of an hour is 60(1/4), namely 15 minutes.


11:20pm + 4 hours, is 11+4:20, namely 15:20, of course the time system only uses up to 12, so that has to be 3:20, and then we add the 15 minutes.


11+4: 20 + 15.........3:35am.

CAN SOMEONE SHOW ME HOW TO DO THIS PLEASE????????????????
morpeh [17]
For (h+g)(x) you just add the two functions:

(h+g)(x) = 4x + 2x^2

For (h•g)(x) you multiply them:

(h•g)(x) = 4x • 2x^2 = 8x^3

For (h-g)(x) you subtract them:

(h-g)(x) = 4x - 2x^2


For (h-g)(-2) you sub -2 into the equation we just created:

(h-g)(-2) = 4(-2) - 2(-2)^2
(h-g)(-2) = -8 - 2(4)
(h-g)(-2) = -8 - 8
(h-g)(-2) = -16

the theaters sell tickets for a concert. tickets for the lower level are $35 each and tickets for the upper level are $25 each.
nasty-shy [4]
Equation 1 for tickets sold:
$35x + $25y = $10,250

Equation 2 for quantity (number #) of tickets sold:
x + y = 350

Use substitution method:

y = 350 - x

35x + 25 (350 - x) = $10,250

35x + $8750 - 25x = $10,250

10x + $8750 = $10,250
- $8,750 -$8,750

10x = 1,500

x = 150

y = 350 - 150

y = 200

Check the answers:

$35 (150) + $25 (200) =

$5,250 + $5,000 = $10,250
