If you would like to solve the inequality x - 5/x < 4, you can do this using the following steps:
<span>x - 5/x < 4
</span>x^2 - 5 < 4x
x^2 - 4x - 5 < 0
(x - 5) * (x + 1) < 0
x < 0
1. x = 5
2. x = -1
The correct result would be x = -1.
Answer:
w=6
Step-by-step explanation:
Simplifying
3(2w + 8) = 60
Reorder the terms:
3(8 + 2w) = 60
(8 * 3 + 2w * 3) = 60
(24 + 6w) = 60
Solving
24 + 6w = 60
Solving for variable 'w'.
Move all terms containing w to the left, all other terms to the right.
Add '-24' to each side of the equation.
24 + -24 + 6w = 60 + -24
Combine like terms: 24 + -24 = 0
0 + 6w = 60 + -24
6w = 60 + -24
Combine like terms: 60 + -24 = 36
6w = 36
Divide each side by '6'.
w = 6
Simplifying
w = 6
Answer:
6,138
Step-by-step explanation:
Given the following:
Vocalist needed :
First day (a) = 6
For subsequent days : number doubles
Using the relation. :
Sn = a(r^n -1)/(r -1)
Where a = first term = 6
r = common ratio = r3/r2 = r4/r3
Since number doubles after each consecutive day, then ; r = 2, n = 10
Sn = 6(2^10 -1)/(2 -1)
Sn = 6(1024 - 1) / 1
Sn = 6144 - 6
Sn = 6138
Answer: 151/14
Step-by-step explanation:
6x+13+4x+16+4x=180
14x + 29 = 180
14x = 151
x = 151/14
Answer:If we have a line given by the equation y=5x−1, what would be the equation of a line parallel to it? A line parallel to this will have the same slope and a different intercept. Since, the slope in the equation is m=5 the slope for the parallel line will be m=5.
