Answer:
Step-by-step explanation:
as you can see they want you to find the total out of the gallons so the first thing you want to do is get 1,688 and 1,297 and multiply both of them the total is 2189336 so 1,688 x 1,297=289336
I would say you cannot use a rectangle. Or a circle. One of those.
Step-by-step explanation:
80 times 2 is 160
Therefore, 100 times 2 is 200
You multiply the denominator and numerator by the same number.
y-axis = altitude in feet
x-axis = minutes
slope = y/x = feet/minute
According to above data, we know that 1800 feet is y-intercept and slope is -300 feet per minute (why slope is negative? because its approaching ground at a constant speed)
a. slope = -300
y-intercept = 1800
b. y = -300 x + 1800
c. Here we are given x = 2 minutes
y = -300(2) + 1800
y = -600 + 1800
y = 1200
The balloon will be 1200 feet high above the ground in 2 minutes.
d. Here we are given 300 feet which is y, and find x minutes.
y = -300 x + 1800
300 = -300x + 1800
300 - 1800 = - 300x
-1500 = -300x
1500 = 300 x
x = 1500 / 300
x = 5
The balloon will reach 300 feet above the ground in 5 minutes.
e. It asking when the balloon will reach the ground, if the balloon reaches the ground than the height will be 0, therefore x-intercept (y=0).
y = -300 x + 1800
0 = -300 x + 1800
-1800 = -300x
1800 / 300 = x
x = 6
The balloon will reach the ground in 6 minutes.

Answer:
y = 3/5 or y = -1/2
v = 0 oe v = -4/3
Step-by-step explanation:
Zero product property states that if ab = 0, then a = 0 or b = 0.
(5y - 3) (2y + 1) = 0
5y - 3 = 0 or 2y + 1 = 0
y = 3/5 or y = -1/2
2v(3v + 4) = 0
2v = 0 or 3v + 4 = 0
v = 0 oe v = -4/3
