Algebra 1 just really teaches you the basics of algrebra
Answer:
B
Step-by-step explanation:
Slope = (y2 - y1)/(x2 - x1)
Slope = (8 - 0)/(3 - 1)
Slope = 8/2
Slope = 4
Answer
4
(b) is the answer.
Step-by-step explanation:
By the Pythagorean Theorem,
A² + B² = C²
Where:
A = Length of side 1
B = Length of side 2
C = Hypotenuse
This rule applies to all right-angled triangles.
The length of the hypotenuse of a right-angled triangle is always the largest value.
Therefore, we can test the answers with the equation above.
(a)
8² + 18² = 20²
64 + 324 = 400
388 ≠ 400
The rule of Pythagorean theorem doesn't work on a, so (a) is not a right-angled triangle.
(b)
12² + 35² = 37²
144 + 1225 = 1369
1369 = 1369
The rule of Pythagorean theorem works here, so (b) is a right-angled triangle.
Answer:
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Negative correlation:-
The negative correlation is a relation between two variables such that they are part of a function in which depends and independent variables move in different directions in terms of value.
<u><em>Positive correlation</em></u>
The variable x - value increases as y- value increases is called positive correlation.
<u><em>Negative Correlation</em></u>
The variable x - value increases as y- value decreases is called negative correlation.
<u><em>No correlation </em></u>
There is no pattern between two variables
there is no connect between two variables is called No - correlation
