Answer: x=y+z
Step-by-step explanation: Let x be the variable which is the price. Y is the price it cost. Z is the percent markup for the price. Hope this helps
Step-by-step explanation:
it is the second option
f(x) = 815.03×(1.38)^x
for year (x) 4 and 5 we need to get f(x) values in the multiple thousands.
the first and fourth options only add very little to 815.03. they can never reach the cost levels needed for the years 4 and 5.
the third option for e.g. x=4 only creates 815.03 × 2 = 1630.06, which is not 2955.65.
so, just to control, for x = 4 we get for the second option
815.03 × (1.38)⁴ = 815.03 × 3.62673936 = 2,955.901381
it is close enough to model the given data.
I think the answer is 9 I'm not sure
This problem can be solved using the
formula
D = rt
Where d is the distance
R is the speed
T is the time
Then establish the two equation
D = 50t
D = 40(t+3)
Equating the two quations
50t = 40(t+3)
T = 12 hrs he took to drive from
alentown to baker
<span>D = 50x12 = 600 miles</span>
The slope is not shown on the problem but whatever the slope is, plug it in the equation below before the x .
Y=__X-2
