Answer:
Enterprise charges more for a 6 day rental. ($284 for Hertz and $294 for Enterprise). Avery would save $4 if he rented with Hertz for 4 days.
Step-by-step explanation:
H = Hertz
E = Enterprise
x = Days rented
T = Total cost for x days, in $
<u>Hertz:</u> TH = 42x + 32
<u>Enterprise: </u> TE= 45x + 24
====================
6 Day Rental:
TH = 42*(6) + 32, = $284
TE = 45*(6) + 24 = $294
4 Day Rental:
TH = 42*(4) + 32, = $200
TE = 45*(4) + 24 = $204

Answer:
At 1.5 seconds and 2.5 seconds
Step-by-step explanation:
Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.
Set that equal to 0 and factor to solve for t:
Using the quadratic formula, we get t = 1.5 and t = 2.5
Answer:
x=-2 y=-6
Step-by-step explanation:
x-4=4x+2
subtract x from both sides
-4=3x+2
subtract 2 from both sides
-6=3x
divide by 3 on both sides
x=-2
y=-2-4=-6
y=4(-2)+2=-8+2=-6
Step-by-step explanation:
3. The triangle that makes up the square is a 45-90-45 triangle so x = 45°. Using Pythagorean theorem,
2y^2 = 12 ---> y^2 = 6
or
y = √6
4.This is an equilateral triangle of side 11 so
y = 11/2
To find x, use the definition of sine 60:
sin 60° = opp/hyp
= x/11
or
x = 11sin60° = (11√3)/2
At 1/8 of a gallon you can mow 2 1/4 so for 1 gallon just multiply 2 1/4 by 8
16+2 is 18
