Uhh didnt I just answer this? It is 3/13
Let us evaluate the equations one at a time.
1) 3x + 5 = -2
3x = -7
x = -7/3
This equation has unique solution.
2) 6(x - 11) = 15 - 4x
6x - 66 = 15 - 4x
10x = 81
x = 81/10
Ths equation has a unique solution
3) 12x + 9 = 8x + 1 + 4x
12x - 8x - 4x = 1 - 9
0x = -8
x = -8/0
This equation has no solution.
4) 2(x - 3) = 10x - 6 - 8x
2x - 6 = 10x - 6 - 8x
2x - 10x + 8x = -6 + 6
0x = 0
x = 0/0
Ths equation has no solution.
5) 5x + 6 = 5x - 4
5x - 5x = -4 - 6
0x = -10
x = -10/0
This equation has no solution.
Answer:
41.92 seconds
Step-by-step explanation:
Level 1 = X
Level 2 = X + 1.283
X = 20.341
Level 2 = 21.579
Level 1 + Level 2 = 21.579 + 20.341
Both levels = 41.92 seconds
Have a good day! ;)
Answer:
A. -10
Step-by-step explanation:
Hi there!
We are given that the equation of line m is , and we want to find the slope of the line perpendicular to m
Perpendicular lines have slopes that multiply to get the result of -1
So let's find the slope of line m
The equation is written in the form y=mx+b, where m is the slope, and b is the y intercept
As is in the place of where the slope should be, is the slope
Now find the slope of the perpendicular line with this formula:
In that case,
Multiply both sides by 10
So the slope of the perpendicular line is -10, or A
Hope this helps!
