We can conclude that -
Isabel will pay $60 if she returns the sound system by 4 p.m.If she is 30 minutes late, then she will pay $72.What is inequality?An inequality compares two or more numbers or expressions with one another. For example -
2x + 4y > 7
2x + 5y < 6
Given is the table that shows the cost of renting a sound system for a concert. Isabel rents a sound system at 1 p.m. and plans to return it before 4 p.m.
The total number of hours for which she will rent the sound system is -
{h} = 4 - 1 = 3 hours
{h} = 3 hours
Now, for 3 hours, the given inequality is -
2 < x ≤ 3
We can write the cost as $60.
If she is 30 minutes late, then she will pay $72.
Therefore, we can conclude that -
Isabel will pay $60 if she returns the sound system by 4 p.m.If she is 30 minutes late, then she will pay $72.To solve more questions on tabular inequality, visit the link below

Suppose that y varies directly with x and y = 10 when x = 20. What is y when x = 15?
Given that,
y varies directly with x and y = 10 when x = 20.
To find,
The value of y when x = 15.
Solution,
[tex]y\propto x\\\\y=kx[/tex]
Put x = 20 and y = 10
[tex]k=\dfrac{y}{x}\\\\k=\dfrac{10}{20}\\\\=\dfrac{1}{2}[/tex]
Put k = 1/2 and x = 15 to find the value of y.
[tex]y=\dfrac{1}{2}\times 15\\\\=7.5[/tex]
So, the value of y is 7.5

If f is the function defined by f(x) = 3x^5 - 5x^4, what are all the x coordinates of points of inflection for the graph of f?
a. -1
b. 0
c. 1
d. 0 and 1
e. -1, 0, and 1
Answer:
D: 0 and 1
Step-by-step explanation:
Function is defined by;
f(x) = 3x^(5) - 5x⁴
Now, an inflection point will be a point on the graph where the inflection or concavity changes.
Thus, let's find the derivatives until we get there;
f'(x) = 15x⁴ - 20x³
f''(x) = 60x³ - 60x²
So factorizing gives;
f''(x) = 60x²(x - 1)
At f''(x) = 0, we have; x = 0 or x = 1
Thus, the x coordinates of points of inflection are 0 & 1

910 = (5x + 10) + 5x
Answer:
The answer is 86 and 96 mph
Step-by-step explanation:
Givens
Train A
Distance traveled = d
time taken = 5 hours
rate traveled = r
Train B
Distance traveled = 910 - d
time taken = 5 hours
rate = r + 10
Formula
basically d = r * t
Solution
Train A: d/r = 5 or d = 5*r
Train B = (910 - d)/(r + 10) = 5 or
Substitute d = 5*r into Train B
(910 - 5*r)/(r + 10) = 5 Multiply both sides by r + 10
(910 - 5r) = 5 * (r + 10) Remove the brackets on both sides
910 - 5r = 5r + 50 Add 5r to both sides
910 = 5r + 5r + 50
910 = 10r + 50 Subtract 50 from both sides
910 - 50 = 10r Combine the left
860 = 10r
10r = 860 Divide by 10
r = 860/10
r = 86
r + 10 = 96
Check
Train A distance: 5*r = 5 * 86 = 430
Train B distance: 5*r = 5 * 96 = 480
Total = 910
