Answer:
Step-by-step explanation:
x=14 is a vertical line with undefined slope
It has no y intercept and has only x intercept of 14.
Answer:
Height = 1 inch
Step-by-step explanation:
area of triangle = 1/2 x base x height
11.5 =1/2 x 23 x height
23/23 = height
height = 1
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)
k/5.2+81.9 = 47.2 // - 47.2
k/5.2-47.2+81.9 = 0
0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2
0.19230769*k = -(81.9-47.2) // : 0.19230769
k = (-(81.9-47.2))/0.19230769
k = 5.20000006*(47.2-81.9)
k = 5.20000006*(47.2-81.9)
Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>

Answer:
f(-4) = 6
f(0) = -6
f(1) = -4
Step-by-step explanation:
Answer:
#3.) The initial value of 16 gal at x = 5 minutes means that 16 gallons of water was present 5 minutes after the barrel started leaking.
#4.) Find how many minutes until the barrel is empty of water.
Let y = 0, to solve for time x.
0 = (-2/5)*x + 18
(2/5)*x = 18
x = (5/2)* 18 = 5*9 = 45 minutes
Up to and after 45 minutes, the barrel is empty of water.
Step-by-step explanation:
#2.)
minutes: 5, 10, 15, 20
water(gal): 16, 14, 12, 10
Find slope: slope m = (14 - 16)/(10 - 5) = -2/5
y - 10 = (-2/5)*(x - 20)
y - 10 = (-2/5)* x + 8
y = (-2/5)*x + 18
rate of change slope means that for every minute 2/5 gallons of water is lost
#3.) The initial value of 16 gal at x = 5 minutes means that 16 gallons of water was present 5 minutes after the barrel started leaking.
#4.) Find how many minutes until the barrel is empty of water.
Let y = 0, to solve for time x.
0 = (-2/5)*x + 18
(2/5)*x = 18
x = (5/2)* 18 = 5*9 = 45 minutes
