To find which point is NOT on the line y = 5x + 1, we just need to plug each point into equation y=5x+1 to see which one point satisfies this equation.
check for (1,6)
y=5x+1
or 6=5*1+1
or 6=5+1
or 6=6
Which is TRUE.
--------
check for (2,11)
y=5x+1
or 11=5*2+1
or 11=10+1
or 11=11
Which is TRUE.
--------
check for (0,1)
y=5x+1
or 1=5*0+1
or 1=0+1
or 1=1
Which is TRUE.
--------
check for (-1,6)
y=5x+1
or 6=5*(-1)+1
or 6=-5+1
or 6=-4
Which is FALSE.
--------
Since only point (-1,6) fails to satisfy the given equation hence point (-1,6) is the final answer.
Answer:
graphhhhhh
Step-by-step explanation:
The slope is -3/4 so you up 3, left 4. or down 3, right 4.
You start at 1 on the y axis and then do this^.
Then you look at the line you have made and see which points are obvious.
You can just copy what I got on the graph below.
-2/-2=1
4/-2=-2
6/-2=-3
The answer is divide by -2.
Answer:
D) x = 1 ± √(47)
Step-by-step explanation:
2x² + 3x - 7 = x² + 5x + 39
move all terms to one side:
x² - 2x - 46 = 0
complete the square:
x² - 2x + 1 - 1 - 46 = 0
(x - 1)² - 47 = 0
add 47 to both sides:
(x - 1)² = 47
square root both sides:
x - 1 = ±√(47)
add 1 to both sides:
x = 1 ± √(47)
