Answer:f(3)=26,f(6)=215
Step-by-step explanation:
f(x)=3^x-1
f(3)=3^3-1
f(3)=3x3x3-1
f(3)=27-1
f(3)=26
f(6)=6^3-1
f(6)=6x6x6-1
f(6)=216-1
f(6)=215
First you put a 1 under the 2.Then you multiply 85*2 and you get 170.Next you multiply 8.2*1 and you get 8.2.Finally, you divide 170 by 8.2 and get 20.73.
So, your answer to 85/8 times 8.2 = 20.73.
Hope that helped.
Answer:
slope = - 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 10x + 5 ← is in slope- intercept form
with slope m = - 10
Answer:
The answer to your question is 166 mi/h
Step-by-step explanation:
Data
ve = rate eastbound train
vw = rate westbound train = ve - 14
distance = d = 900 mi
time = t = 5 h
Formula
v = 
Substitution and simplification
Now, substitute this value in the equation of vw
vw = 180 - 14
Result
vw = 166 mi/h
Y = mx + b
y = -4x -2
trying option 1
-8x + 2y = -4
2y = -4 + 8x
y = -2 + 4x
so its incorrect
Now trying option 2
8x + 2y = -4
2y = -4 - 8x
y = -2 - 4x
y = -4x -2
so Option B is correct
