Answer:
V= -2000t + 20000
Step-by-step explanation:
Let m be the slope of our function :
- m=(20000-16000)/(0-2)= -2000
- so our function is V= -2000t + b
- b is the intitial price so b = 20000
- then : V= -2000t + 20000
Let's check :
- take the second year : V= -2000*2 +20000 = 16000
- that's true !
Answer:
The mistake they made was they switched the slope and y-intercept.
The correct answer is y=2x+7 because when we write an equation in slope intercept form (y=mx+b) you replace m with the slope and b with the y-intercept.
Hope this helps! <3
Step-by-step explanation:
(x - 8) (x + 8) = x² - 64
because
x² + 8x - 8x - 64
(a⁵)^-1 = 1/(a⁵)
that is the definition of a negative exponent. it means 1/...
