Answer:
<em>6497</em>
Step-by-step explanation:
127% is the same as 1.27
Let the number be x.
127% of a number x is the same as 1.27x.
1.27x = 8251
x = 6497
The number is 6497.
Answer:
slopes are the same
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 5x - 6 ← is in slope- intercept form
with slope m = - 5
Calculate the slope between the 2 points using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 6) and (x₂, y₂ ) = (2, - 16)
m = = = - 5
The slope of the line and the slope between the 2 points are the same
2/3 x 1/2 = 2/6 = 1/3

<span>x-y=1 (1)
x+y=3 (2)
Add (1) and (2) to eliminate y:
x- y + x - y =1 + 3
2x = 4
x = 4/2
</span><span>x = 2
Substitute x = 2 into (1) to find y:
2 + y = 3
y = 3 - 2
y = 1
The solution is (2, 1) </span>
