Answer:
Step-by-step explanation:
When you have an inequality like this, you can treat it like an equation except for one part. If you ever divide or multiply it by a negative number or variable you have to flip the inequality. if it is equal to as well you keep that though. for instance
-5x ≤ 10
x ≥ -2
Anyway, in your case you have two inequalities, so you have to solve both and see what makes both true.
We'll start with 12x - 39 ≤ 9
12x - 39 ≤ 9 First add 39 to both sides
12x ≤ 48 Now divide both sides by 12, positive so no flipping
x ≤ 4
Next is:
-4x + 3 < -6 First subtract 3 from both sides
-4x < -9 Now divide both sides by -4, which means the sign flips
x > 9/4
Now, without even looking at the answers, what number or numbers are less than or equal to 4 and greater than 9/4? Well we pretty much described it there. All numbers starting from, though not including 9/4, which is 2.25, all the way up to, and including 4. B shows exactly that.
To solve the inequalities, the first is simplified to x > 4 and the second to x > 2.25 after applying proper arithmetic operations and considering the signs during division.
The student's question involves solving two inequalities, one of which is a linear inequality, and the other an inequality that requires adding or subtracting to isolate the variable. To solve the inequality 12x - 39 > 9, we add 39 to both sides to get 12x > 48, then divide both sides by 12 to find that x > 4. For the inequality -4x + 3 < -6, we subtract 3 from both sides to get -4x < -9, then divide by -4, remembering that dividing by a negative number reverses the inequality, resulting in x > 9/4 or x > 2.25.

Answer:
A(-3, -7) B(2,-1) C(-2,0) D(-5,6)
Step-by-step explanation:
A(3,7) B(-2,1) C(2,0) D(5,-6)
180 rotation around origin = (-x,-y)
A(3,7) - A(-3,-7)
B(-2,1) - B(2,-1)
C(2,0) - C(-2,0)
D(5,-6) - D (-5,6)
Answer:
A(-3, -7) B(2,-1) C(-2,0) D(-5,6)
Step-by-step explanation:
A(3,7) B(-2,1) C(2,0) D(5,-6)
180 rotation around the origin would equal (-x,-y)
A(3,7) - A(-3,-7)
B(-2,1) - B(2,-1)
C(2,0) - C(-2,0)
D(5,-6) - D (-5,6)
The geometric mean of the two numbers 64 and 25 is 40 after applying the geometric mean formula.
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
Two numbers are: 64 and 25
As we know, in the geometric sequence:
The geometric mean can be defined as:
GM = √ab
Here GM is the geometric mean
a and b are the numbers
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.
GM = √(64x25)
GM = 8x5
GM = 40
Thus, the geometric mean of the two numbers 64 and 25 is 40 after applying the geometric mean formula.
