When there is a line under it means no more than!
Answer:
(-1, -2) will be the solution.
Step-by-step explanation:
System of equations has been given as,
y = 3x + 1 ---------(1)
Input-output value table for the given line will be,
x -2 -1 0 1
y -5 -2 1 4
y = -x - 3 ----------(2)
Input-output value table for the given line will be,
x -2 -1 0 1
y -1 -2 -3 -4
By plotting the given coordinates we can draw the straight lines.
And the point of intersection (common point) of these lines will be the solution of the given system of equations.
Hence, (-1, -2) will be the solution.

Add 3x to both sides
2y=3x+4
Divide both sides by 2 so that the only thing remaining on the left side is the variable y.

Answer:
Scale factor = 3.24
Step-by-step explanation:
162 ÷ 50 = 3.24
Answer:
option D
Yes, they are independent because P(A)×P(B)=P(A∩B)
Step-by-step explanation:
Given in the question,
p(A) = 3/5
p(B) = 4/7
p(A∩B) = 12/35
If two events A and B are independent then,
<h3>P(A n B)= P(A).P(B)</h3>
12/35 = 3/5 . 4/7
12/35 = 12/35
Hence, events A and B independent events
