Answer:
A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1
Step-by-step explanation:
Which statements are true? Mark all that apply. A If y³ = 27, the value of y is 3. B If y³ = 64, the value of y is 4. C If y³ = 1, the value of y is 1. D If y³ = 16, the value of y is 2.
Solution:
a) y³ = 27
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛27
y = 3
Option A is correct
b) y³ = 64
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛64
y = 4
Option B is correct
c) y³ = 1
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛1
y = 1
Option C is correct
d) y³ = 16
To solve this, we have to take the cube root at both sides of the equation and then simplify, that is:
∛y³ = ∛16
y = 2.52
Option D is wrong

Shown in the second Figure below
<h2>
Step-by-step explanation:</h2>
This is an inequality we must solve. Recall that an inequality tells us that two values are different. To solve this inequality, we need to plot the line:
The graph is shown in the first Figure below. The solution can be found by testing a point, namely (0, 0), and verifying if this point meet the requirement of the inequality as follows:
The solution is the part of the graph having black lines.
These both represent the same number.
In $4.30 or just 4.30, the zero does not have any number after it, so it doesn't need to be there as a placeholder. When you take away the zero, it's just 4.3.
