Here is a system of linear equations:
6x+21y=103
-6x+23y=51
Would you rather use subtraction or addition to solve the system? Explain your reasoning.
Step-by-step explanation:
6x + 21y = 103
-6x + 23y = 51
The signs of the x coefficients are opposite. So adding the equations will eliminate the x terms.
44y = 154
y = 3.5
Combining the equations will remove the x terms because the x coefficients have inverse signs. The solution to the given system of linear equations is x = 4.92 and y = 3.5.
What is the equation?The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.
Here is a system of linear equations:
⇒ 6x + 21y = 103
⇒ -6x + 23y = 51
Inverse signs can be seen in the x coefficients. The x terms will therefore be removed after adding the equations.
⇒ 44y = 154
⇒ y = 3.5
Substitute the value of y = 3.5 in the equation 6x + 21y = 103
⇒ 6x + 21(3.5) = 103
⇒ 6x + 73.50 = 103
⇒ 6x = 103 - 73.50
⇒ 6x = 29.50
⇒ x = 4.92

What do you observe about the distances between the three pairs of corresponding vertices for each movement Based on your observations, how would you define a translation? How can you extend what you know about the vertices of a shape to all the points on a shape during a translation?
Answer:
The Observation made about the distances between three pairs of corresponding vertices is that the distance between each translated pair must be equal to the distance between every translated pair . i.e distance between A and A' = distance between B and B' = distance between C and C'
Step-by-step explanation:
The Observation made about the distances between three pairs of corresponding vertices is that the distance between each translated pair must be equal to the distance between every translated pair . i.e distance between A and A' = distance between B and B' = distance between C and C'
from this observation Translation is the movement of all vertices of shapes at a fixed distance along a given co-ordinate, The movement of the vertices of a shape at a fixed distance is just another way of defining the movement of the points of a shape at a fixed distance in relation to translation
Answer:
Each distance between the three pairs of corresponding vertices is the same. Based on this observation, a translation is a transformation in a coordinate plane that moves the vertices of a shape a fixed distance. In fact, a translation moves all points on a shape a fixed distance.
Step-by-step explanation:
Point V lies between points U and W on line UW. The distance between U and V is 2x-4, and the distance between V and W is 4x+10. If UW = 9x – 9, what is UW in units?
Answer:
36UNITS
Step-by-step explanation:
If point V lies between U and W, then UV+VW = UW
given parameters
UV = 2x-4
VW = 4x+10
UW = 9x-9
Substituting the given functions in the formula first, we will have;
2x-4+4x+10 = 9x-9
6x+6 = 9x-9
Collect like terms
6x-9x = -9-6
-3x = -15
x = -15/-3
x = 5
Substitute x = 5 into UW.
Since UW = 9x-9
UW = 9(5)-9
UW = 45-9
UW = 36

1. Translate: A number divided into 4 2. Translate: The sum of 2/3 and a number 3. Translate: Drew is "n" years younger than Joe who is 9 years old
Answer:
1. x/4
2. 2/3+x
3. 9-n
Step-by-step explanation:
1. "A number" is an unknown value, so we set that as the variable. When a number is being divided, it's the divisor in a division problem (the first number)
2. The "sum" is the answer to an addition problem (like how the "quotient" is the answer to a division problem), which is why we know to add. Again, "a number" is the unknown value so we set that as the variable.
3. Because Drew is "n" years younger than Joe, Joe's age - n = Drew's age. The question tells us that Joe is 9 years old, so the expression would be 9-n.
I hope this helps! If it does, a brainliest would be much appreciated :)

Length of [tex]\boldsymbol{AC}[/tex] is [tex]\boldsymbol{22}[/tex] units.
"To understand the calculation, check below."
Midpoint
The middle point of the a line segment is called the midpoint.
It's really the centroid of both segment and the ends, and it is equidistant from both.
It cuts the portion in half.
[tex]B[/tex] is the midpoint of [tex]
AC[/tex] [tex]\boldsymbol{AB=BC}[/tex][tex]3x-1=x+7[/tex] [tex]2x
AC=8[/tex] [tex]\boldsymbol{x=4}[/tex]

Cheryl wants you find the number of hours 7th graders do work at home each week. There are 297 boys and girls in 7th grade, Cheryl random surveyed 50 girls in the entire school to find a number of our 7th graders do homework each week described why she would get a biased sample
Answer: There are a total of 297 students in the 7th grade. Rough estimates would say that about half of that number are boys and half are girls. Asking only 50 random girls would be biased because not only would it not be all of the girls (the number of girls would be around 148 or 149) but it would also be ignoring the roughly 148 to 149 boys there are on estimate. The sample would be biased because it would be ignoring the opinions of more than half the seventh grade.
(FULL CREDIT TO maksimylian, I DID NOT WRITE THIS ANSWER)
Answer:
Randomly surveying 50 girls would most likely bring non-seventh-graders into the sample.
The sample also does not take any boys into account, and they most likely make up about half of the seventh-grade population.
The results would not be a representative sample of the population.

Answer:
The slope of a line can be positive, negative, zero, or undefined. A horizontal line has slope zero since it does not rise vertically (i.e. y1 − y2 = 0), while a vertical line has undefined slope since it does not run horizontally (i.e. x1 − x2 = 0).

George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL. What is the volume of the object?
Answer: 20 mL
Step-by-step explanation:
According to Archimedes, the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.
i.e. weight of the object = weight of the fluid displayed
Given: George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL.
So, the volume of the object = New volume - Original volume
= 45 mL - 25 mL
= 20 mL
Hence, the volume of the object =20 mL

[tex]1-\cos \left(x\right)[/tex]
Step-by-step explanation:
[tex]\frac{\sec \left(x\right)\sin ^2\left(x\right)}{1+\sec \left(x\right)}[/tex]
Use the identity: [tex]\sec \left(x\right)=\frac{1}{\cos \left(x\right)}[/tex]
[tex]\frac{\frac{1}{\cos \left(x\right)}\sin ^2\left(x\right)}{1+\frac{1}{\cos \left(x\right)}}[/tex]
[tex]\frac{\frac{1}{\cos \left(x\right)}\sin ^2\left(x\right)}{\frac{\cos \left(x\right)+1}{\cos \left(x\right)}}[/tex]
[tex]\frac{\frac{\sin ^2\left(x\right)}{\cos \left(x\right)}}{\frac{\cos \left(x\right)+1}{\cos \left(x\right)}}[/tex]
Divide them using [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\times d}{b\times c}[/tex]
[tex]\frac{\sin ^2\left(x\right)\cos \left(x\right)}{\cos \left(x\right)\left(\cos \left(x\right)+1\right)}[/tex]
Cancel cos(x):
[tex]\frac{\sin ^2\left(x\right)}{\cos \left(x\right)+1}[/tex]
Use the identity: [tex]\sin ^2\left(x\right)=1-\cos ^2\left(x\right)[/tex]
[tex]\frac{1-\cos ^2\left(x\right)}{1+\cos \left(x\right)}[/tex]
[tex]\frac{-\left(\cos ^2\left(x\right)-1\right)}{1+cos(x)}[/tex]
Use the difference of squares formula:
[tex]-\frac{\left(\cos \left(x\right)+1\right)\left(\cos \left(x\right)-1\right)}{1+\cos \left(x\right)}[/tex]
Cancel out 1+cos(x):
[tex]-\left(\cos \left(x\right)-1\right)[/tex]
Remove outer bracket:
