Answer:
yes
Step-by-step explanation:
f(x) = 6x² - 9x - 6 = 2x² - 3x - 2
= (x + 0.5)(2x - 4)
= [2x² - 4x] + [0.5(2x) + 0.5(-4)]
= 2x² - 4x + 0.5(2x) + 0.5(-4)
= 2x² - 4x + 1x + (-2)
= 2x² - 3x - 2
I think it would be b or c
Answer:
False
Step-by-step explanation:
Sorry for the lat reply hopefully you still have that question ready. But basically in order for these equations to be considered inverses of one another it has to map its domain value and switch it to the range value and in this case it does not match the inverse when graphed.
Answer:
C) x/21
Step-by-step explanation:
Since Person 1 can complete the entire job (100% = 1/1 = 1) in 21 minutes, this person can complete 1/21 of the job per minute. This is Person 1's rate. If x is the amount of time it takes both people together to finish the job, then the amount of work Person 1 does would be (1/21)(x) = x/21.
R =
= 3.6 and A = 2
given that R is inversely proportional to A, then
R =
← k is the constant of variation
To find k use the condition R = 12 when A = 1.5
k = RA = 12 × 1.5 = 18
the equation is therefore
R = ![\frac{18}{A}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7BA%7D)
when A = 5, then
R =
= 3.6
when R = 9, then
9 =
( multiply both sides by A )
9A = 18 ( divide both sides by 9 )
A = 2
