Answer:
y = -3/2x - 3
Step-by-step explanation:

y = -3/2x + b
Step 2: Find y-intercept <em>b</em>
3 = -3/2(-4) + b
3 = 6 + b
b = -3
Step 3: Rewrite linear equation
y = -3/2x - 3
<h3>Answer:</h3>
- Calvin: incorrect, sign error
- Greg: incorrect, has no relationship to the given expression
- Ruben: incorrect, sign error
- Equivalent expresssion: 7 92(4x -11)
<h3>Explanation:</h3>
The two terms on the right, -8x and +22, have even coefficients, so a factor of 2 can be factored out. If we do that, then these two terms become ...
... 2(-8x/2 +22/2) = 2(-4x +11)
We could, instead, factor out -2 so the x-coefficient inside parentheses is positive:
... -2(-8x/-2 +22/-2) = -2(4x -11)
Note that the signs of the two terms inside parentheses are different no matter which way we do it.
<u>Equivalent expressions</u>
Calvin could have written: 7 -2(4x -11)
Ruben could have written: 7 +2(-4x +11)
Greg could have written: 8(2 -x) -1. He would have rearranged the expression to 16 -8x -1 before doing so.
Answer:
True : If A and B are independent events, then P(A|B)=P(A) is true.
Step-by-step explanation:
If A and B are independent, P(A and B) = P(A) * P(B)
P(A|B) conditional probability, P(A) given B has already happened
= P(A and B) / P(B)
= P(A)*P(B) / P(B)
= P(A)
Therefore
If A and B are independent events, P(A|B)=P(A) is true.
Answer:
option C.
Step-by-step explanation:
According to equidistant chords theorem, two chords of a circle are congruent if and only if they are equidistant from the center of the circle.
Congruent means they are equal in length.
Using equidistant chords theorem, we can fill the blank.
In a circle, two chords that are equidistant from the center of the circle are always equal in length.
Therefore, the correct option is C.
