Answer:
[tex]-3 < x < -2[/tex]
Step-by-step explanation:
Seperate compound inequalities into system of inequalities: [tex]\left \{ {{-3x-4 > 2} \atop {-3x-4 > 5}} \right.[/tex]
Rearrange unknown terms to the left side of the equation: [tex]-3x > 2+4[/tex]
Calculate the sum or difference: [tex]-3x > 6[/tex]
Reduce the greatest common factor for both sides of the inequality: [tex]-x > 2[/tex]
Divide both sides of the inequality by the coefficient of the variable: [tex]x < -2[/tex]
Rearrange unknown terms to the left side of the equation: [tex]-3x < 5+4[/tex]
Calculate the sum or difference: [tex]-3x < 9[/tex]
Reduce the greatest common factor for both sides of the inequality: [tex]-x < 3[/tex]
Divide both sides of the inequality by the coefficient of the variable: [tex]x > -3[/tex]
Find the intersection: [tex]-3 < x < -2[/tex]

What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
We know rotating a planer figure counterclockwise transforms
(x, y) to (-y, x) and the image remains congruent to the preimage.
Given, A quadrilateral PQRS in which PQ is parallel to SR and PS is parallel to QR.
Rotating PQRS 90 degrees counterclockwise P'Q' is parallel to R'S' and
Q′R′ is parallel to P'S'.

Hey, can someone help me with this. I am having trouble
How many 32-bit integers can be stored in a 16-byte cache line?.
Answer:
4
Step-by-step explanation:
1 byte = 8 bits
=> 16 byte = 16 x 8 = 128 bits
So it can hold 128 : 32 = 4 integers.
The number of 32-bit integers that can be stored in a 16-byte cache line is 4.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
It is known that,
1 byte = 8 bits
Multiply both sides by 16
16 byte = 128 bits
32 bits will hold 128/32 = 4 integers.
Hence "A 16-byte cache line can hold a maximum of 4 32-bit integers".

How many solutions does the system have
Answer:
There are infinate solutions.
Step-by-step explanation:
Plug (3x-8) in for y
5(3x-8)=15x-40
Simplify
15x-40=15x-40
Explanation:
If we multiply both sides of the second equation by 5, then we go from y = 3x-8 to 5y = 15x-40. This is exactly identical to the first equation of the system.
Therefore, the two equations are equivalent just in slightly different forms. The two equations graph the same line which leads to infinitely many solutions.
The solutions are of the form (x, 3x-8) where x is any real number.
Since there are infinitely many solutions, we consider this system to be dependent.

In Mrs. Nathan's class, there are 8 boys and 10 girls. What is the ratio of girls to boys in Mrs. Nathan's class? A. 5:4 B. 1:8 C. 8:1
Answer:
A. 5:4
Step-by-step explanation:
There are 10 girls and 8 boys, so the ratio of girls to boys would be 10:8. BUT we are going to simplify it. 10 and 8 both can be divided by 2, so we get a ratio of 5:4.
Answer:
[A] 5:4
Step-by-step explanation:
There are 8 boys and 10 girls.
What is the ratio of girls to boys in Mrs. Nathan's class?
10:8 is the ratio
As you can see that not a answer choice.
That cause you have to simplify.
Find the GCF. [2]
Hence, 10:8 both divide by 2
= 5:4
Thus, Answer = [A] 5:4

Which equations have the variable term in the equation -6 + 2x = 6x - 9 Isolated to one side of the =, and the constant isolated to the other side? Select all that apply.
Answer:
See explanation.
Step-by-step explanation:
Since no choices were given I'll do my best to provide equivalent options.
Let's say all the terms with x in them were moved to the left side of the equation, and the rest were moved to the right.
-6+2x = 6x-9
2x-6x = -9+6
Simplifying these gives:
-4x = -3
4x = 3
Based on your question you should look for functions arranged similarly to
-4x = -3
The options for this question might include:
-4x = -3
4x = 3
2x - 6x = -9 + 6
-6 + 9 = 6x - 2x
3 = 4x

Solve the system of equations by multiplying first. Enter the solution as an ordered pair.
x + 3y = -11
4x + 7y = -24
Answer:
(1, -4)
Step-by-step explanation:
In this system, multiply the top equation by -4. this will give you
-4x - 12y = 44
4x + 7y = -24
the x values can now cancel out, and add the other values together
-5y = 20
y = -4
now, substitute y = -4 in for one of the starting equations
x + 3(-4) = -11
x - 12 = -11
x = 1
