What is the solution of the linear system of equations? please helpy=2x-3
y=2x+5
A.
(0, –3)
B.
(0, 5)
C.
(–3, 5)
D.
no solution
Answers
2x-3=y=2x+5
2x-3=2x+5
minus 2x oth sides
-3=5
false
no solution
(we can see that since slopes are same and y intercepts are differnt, the lines are paralell and therfor never intersect)
D. No solution

Answers
Answer:
Option A is correct .i.e., Slope is -1.
Step-by-step explanation:
Given points are K(c+d , c-d) & L(c-d , c+d)
Therefore, Option A is correct .i.e., Slope is -1.
Answer A
slope= (c+d-(c-d))/(c-d-(c+d))=2d/(-2d)=-1

They are independent because P(X) + P(Y) = P(X and Y).
They are dependent because P(X) · P(Y) = P(X and Y).
They are dependent because P(X) + P(Y) = P(X and Y).

Answer:
They are independent because P(X) · P(Y) = P(X and Y).
Step-by-step explanation:
Two events are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. This means that the probability of both events happening is equal to the product of the probabilities of each event happening individually.
In the given situation, we have:
P(X) = 1/2
P(Y) = 1/2
P(X and Y) = 1/4
If we calculate the product of P(X) and P(Y), we get:
P(X) · P(Y) = 1/2 · 1/2 = 1/4
This is equal to P(X and Y), which means that the events X and Y are independent.
P(X) + P(Y) = P(X and Y) is not a necessary condition for independence. For example, the events of flipping a coin and rolling a die are independent, but P(X) + P(Y) ≠ P(X and Y).
Therefore, the best description of the events is that they are independent because P(X) · P(Y) = P(X and Y).

What is Unitary Method?
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Dan painted 3/4 of a wall using 1/4 of a can of paint.
So, 1/4 can used = 3/4 of wall
Then, in one can the amount of wall painted
= 3/4 x 4/1
= 3 walls.
