Y=3x+62x+4y=−4 What is the value of y in the system?
1 answer:
9514 1404 393
Answer:
y = 0
Step-by-step explanation:
We assume you want to find y such that ...
- y = 3x +6
- 2x +4y = -4
Dividing the second equation by 2, we can write an expression for x.
x +2y = -2
x = -2y -2
Substituting this into the first equation gives ...
y = 3(-2y -2) +6
y = -6y -6 +6 . . . eliminate parentheses
7y = 0 . . . . . . . . . add 6y
y = 0 . . . . . . . . . . divide by 7
The value of y in the system of equations is 0.

Answer:
Option (d).
Step-by-step explanation:
Note: The base of log is missing in h(x).
Consider the given functions are
The function m(x) can be written as
...(1)
The translation is defined as
.... (2)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
Therefore, we have to translate each point of the graph of h(x) 3 units left to get the graph of m(x).
Hence, option (d) is correct.
