Answer:It should be x=1 not sure thought.
Step-by-step explanation:
The highest is 7 degrees and lowest is -8 so subtract and you get a difference of 15 degrees
Answer:
i think it is 1
Step-by-step explanation:
Both equations are the same
<span>y=−4x+4 ----> y+4x=4,
so </span><span>consistent dependent</span>
Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
