Answer:
Step-by-step explanation:
y = mx + b
y = -x/3 + b
1 = -2/3 + b
b = 5/3
y = -x/3 + 5/3
Answer:
C(t) = $28,000(0.811)^t (Answer A)
Step-by-step explanation:
The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation.
Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)
Answer: Subtract 3 from each side of the equation(A)
Step-by-step explanation:
3n2−15n=3
1:Subtract 3n2 from both sides.
-15n=3-3n2
2:Divide both sides by -15.
-15n/-15=3-3n2/-15
3:Dividing by −15 undoes the multiplication by −15.
n=3-3n2/-15
4:Divide 3−3n 2 by −15
n=n2-1/5
Answer:
70 inches
Step-by-step explanation:
Larry forms a right triangle with the ground (this is one leg of a right triangle) and he is 24 inches from his shadow (this is the second leg).
74 inches is the hypotenuse of the right triangle
use pythagorean theorem: a^2 + b^2 = c^2
let h = Larry's height
h^2 + 24^2 = 74^2
h^2 + 576 = 5476
h^2 = 4900
h = sq rt 4900
h = 70
24 students walk and bus (total combine)
x is number of students walk
5 times as many students take bus as those who walk, then 5x
x + 5x = 24
6x =24
x =24/6
x = 4
answer: 4 students walk
4 x 5 = 20 students take bus
