Step-by-step explanation:
this is one-dimensional ? everything just on one number line ?
TU = 2 - -17 = 2 + 17 = 19
TU is 19 units long (17 units on the negative side, and 2 units on the positive side of the number line).
therefore, to make TU = UV a true statement, UV has also to be 19 units long.
as U = 2,
V = U + UV = 2 + 19 = 21
It depends on your Divisor, Product, or Value. There is just not a gaven value for X or X=0

Answer:</h3>
C) $12,000
<h3>
Step-by-step explanation:</h3>
4/5 = 9600
÷4
1/5 = 2400
4/5 + 1/5 = 5/5 = the whole price
9600 + 2400 = 12000
=$12,000
The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).
<h3>What is a regression line?</h3>
A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.
According to the given problem,
From the table we can see,
ln(Element) is the dependent variable and Time is the independent variable.
The constant = 2.305,
Time = -0.101
Hence, we can conclude, our least squared regression line will be
In (Element) = 2.305 - 0.101 (Time).

Answer:
<u>The system has two solutions:</u>
<u>x₁ = 5 ⇒ y₁ = -10</u>
<u>x₂ = -2 ⇒ y₂ = 11</u>
Step-by-step explanation:
Let's solve the system of equations, this way:
y = -3x + 5
y = x ² - 6x - 5
Replacing y in the 2nd equation:
y = x ² - 6x - 5
-3x + 5 = x ² - 6x - 5
x ² - 3x - 10 = 0
Solving for x, using the quadratic formula:
(3 +/- √(9 -4 * 1 * -10))/2 * 1
(3 +/- √9 + 40)/2
(3 +/- √49)/2
(3 +/- 7)/2
x₁ = 10/2 = 5
x₂ = -4/2 = -2
x₁ = 5 ⇒ y₁ = -10
x₂ = -2 ⇒ y₂ = 11
<u>As we can see the system has two different solutions</u>
