Based on the equation, y = -750·x + 8500, the estimated value of a
motorcycle that is 5 years old is <u>$4,750</u>.
<h3>How can the given equation help to estimate the value of the motorcycle?</h3>
The regression equation that models the data is; y = -750·x + 8500
Where;
y = The value of the brand of motorcycle in dollars
x = The age of the motorcycle
When the motorcycle is 5 years old, we have;
x = 5
y = -750 × 5 + 8500 = 4750
Based on the equation, the estimated value of a motorcycle that is 5 years old, y =<u> $4,750</u>

Answer (2x + 7) • (x2 - 2)
Step-by-step explanation:
please give me brainlest!!
Step by step solution :
Step 1 :
Trying to factor as a Difference of Squares :
1.1 Factoring: x2-2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 2 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares.
Final result :
(2x + 7) • (x2 - 2)
Answer:
Step-by-step explanation:
we know that
The tangency point on the x-axis is (r,0)
The tangency point on the y-axis is (0,r)
Find the slope of the line containing the points of tangency
Remember that the equation of the line into slope intercept form is equal to
where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have
substitute
