Answer:
x= 2,
,y = 5
Step-by-step explanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 5
// Plug this in for variable y in equation [2]
[2] -4x + 2•(5x-5) = 2
[2] 6x = 12
// Solve equation [2] for the variable x
[2] 6x = 12
[2] x = 2
// By now we know this much :
x = 2
y = 5x-5
// Use the x value to solve for y
y = 5(2)-5 = 5
Solution :
{x,y} = {2,5}
That would be (1,0) if its not right than i'm truly i'm not that good at plotting points <span />
Answer:
The equation of a line parallel to the line and passing through (1, -1) is:
Step-by-step explanation:
Given the line
y = -3
We know that the slope-intercept form of the line equation is
where m is the slope and b is the y-intercept
Thus, the slope of the equation y=-3 will be m = -3
We know that the parallel lines have the same slopes.
Thus, the slope of the parallel line will also be -3.
Thus, using the point-slope form to find the line equation is
substituting the values m = -3 and the point (1, -1)
y-(-1) = -3(x-1)
y+1 = -3x+3
y=-3x+3-1
y=-3x+2
Thus, the equation of a line parallel to line and passing through (1, -1) is:
The perimeter of the school crossing sign is 102 inches
length of each side = ?
in the question number of sides is not mentioned, so the answer may vary for the length of each side. if there is 5 sides divide 102 by 5, we get 20.4 answer so in case of 5 sides length of each side is 20.4 inches. if there is 4 sides divide 102 by 4 and we get 25.5 inches answer for the legnth each side.
Answer:
Assuming you're solving for <em>n</em>, 1. n=-1 2. n=-1.6
Step-by-step explanation:
1. -5(2-5n)+6=-5n-34-2
Distributive Property
-10+25n+6=-5n-32-2
Add Like Terms
-4+25n=-5n-34
Subtract -4
25n=-5n-30
Subtract -5n
30n=-30
Divide by 30
n=-1
2. -5(2-5n)+6=-5n-34-20
Distributive Property
-10+25n+6=-5n-32-20
Add Like Terms
-4+25n=-5n-52
Subtract -4
25n=-5n-48
Subtract -5n
30n=-48
Divide by 30
n=-1.6
