Answer:
Step-by-step explanation:
|√2-y|=|y-√2|
√2-y=±(y-√2)
when √2-y=y-√2
y+y=√2+√2
2y=2√2
y=√2
when √2-y=-(y-√2)
√2-y=-y+√2
or 0=0
it gives no value of y.
so only possible value is y=√2
Answer:
<h2>
Bike A costs $270 and has an expected maintenance cost of $36 per year.</h2><h2 /><h3>
"Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."</h3>
Step-by-step explanation:
270-36x
there are 5 years so x=5
270 + 36(5) = 270 + 180 = <u>450</u>
If it were 6 years than x = 6
270 + 36(6) = 270 + 216 = <u>486</u>
Bike B:
360 + 20x
For option b x = 5
360 + 20(5) = 360 + 100 = 460
for option b it would be 6 years than x = 6
360 + 20(6) = 360 + 120 = <u>480</u>

Answer:
C. y = 2x² +8x +6
Step-by-step explanation:
Reflecting f(x) across the y-axis changes the sign of x, so the new function is ...
f(-x)
Vertical scaling by a factor of "a" multiplies the function value by "a", so the new function is ...
a·f(x)
Doing both gives you ...
y = a·f(-x)
y = ax² +4ax +3a
None of the answer choices look like this. However, they match this if a=2:
y = 2x² +8x +6
Answer:
The exponential model is 
.
Step-by-step explanation:
The exponential model can be modelled by the following mathematical expression:
(1)
Where:
- Independent variable.
- Dependent variable.
- Coefficients.
If we know that 
and 
, then we get the following system of equations:
(2)
(3)
If we divide (3) by (2), we calculate the value of 
:
And by (2), we determine the value of 
:
The exponential model is .
