The matrix that represents the system of equations is:
| 3 -2 |
| 4 -1 |
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
We can write the system of equations in matrix form as AX = B, where:
A = the coefficient matrix of x and y coefficients
X = the column matrix of variables x and y
B = the column matrix of constants on the right-hand side of the equations
The matrix A is obtained by taking the coefficients of x and y from the left-hand side of the equations:
A = | 3 -2 |
| 4 -1 |
The matrix B is obtained by taking the constants from the right-hand side of the equations:
B = | 9 |
| 12 |
So the system of equations can be represented as:
| 3 -2 | | x | | 9 |
| 4 -1 | x | y | = | 12 |
Therefore, the matrix that represents the system of equations is:
| 3 -2 |
| 4 -1 |

Dara’s computer monitor is 20 inches wide and 12 inches high. Which measurement is closest to the length of the diagonal of Dara’s monitor?
Answers
Answer:
23
Step-by-step explanation:
20x20=400
12x12= 144
400+144=544 sqaure root it and u get 23
The length of the diagonal of Dara’s monitor will be 23.32 inches.
What is the right triangle?A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.
Dara’s computer monitor is 20 inches wide and 12 inches high.
As we can see that the right triangle in the attached figure
Here the length of the diagonal of Dara’s monitor is equal to the hypotenuse.
According to Pythagoras's theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
So 20² + 12² = d²
400 + 144 = d²
d² = 544
d = 23.32
Thus, the length of the diagonal is 23.32 inches.

if triangle ABC is similar to triangle DEF, find the value of x. AB is x and BC is 28. DE is 25 and EF is 20.
Answers
Answer:
x (or AB)=35
Step-by-step explanation:
x/25=28/20
20x=28x25
20x=700
x=35
The length of AB is 35 units
What is Similarity in Triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable. Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS),
Given:
ΔABC ~ ΔDEF then the ratio of their corresponding sides are equal
AB/ DE = BC/ EF = AC / DF
So, AB/ DE= BC / EF
x/ 25 = 28 / 20
x/25 = 7/5
x= 5 x 7
x= 35
Hence, the length of AB is 35 units

Renee is creating a rectangular garden in her backyard. The length of the garden is 8 feet. The perimeter of the garden must be at least 30 feet and no more than 32 feet
Answers
Answer: One width of the garden can be 3.8 feet.
Step-by-step explanation: To find the perimeter of the garden, multiply the length by the width. Our width is 3.8 feet and our length is 8 feet.
3.8 x 8 = 30.4 feet.
The perimeter could be 30.4 feet because the garden is at least 30 feet and no more than 32 feet.
So, a width of 3.8 feet would work.

Answers
Answer:
g(x)=f(x)-5
Step-by-step explanation:
the negative inside the parenthesis reduces the x values but we have the y value reduced by 5 here so it goes outside
The equation represents g(x) as a transformation will be g(x) = f(x) - 5. Then the correct option is A.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
From the graph, we can observe that the function g(x) is 5 units below the function f(x).
If the function gets shifted downward by k units then the k is subtracted from the function. Then the function g(x) is given as,
g(x) = f(x) - 5
The equation represents g(x) as a transformation will be g(x) = f(x) - 5. Then the correct option is A.

The computer store sells both tablets and laptops. A tablet costs 1500 and a laptop costs 2500 . The store manager wants to sell enough devices to reach the sales goal of 52500 if the store sells 10 tablets, how many laptops the store needs to reach its goal?
Answers
Answer:
1500t and 2500l
52500= 10× 1500 + 2500 l 52500= 15,000 +2500 Hence 15 laptopsAnswer:
15 laptops.
Step-by-step explanation:
You need to find the money earned by selling 10 tablets which is:
1500 x 10 = 15 000
After that, minus the amount of money needed for the goal from the amount of money earned from selling 10 tablets.
52 500 - 15 000 = 37 500
The remaining amount of money is the amount of money you get after finding out how much you make from selling 10 tablets. Use the remaining and divide it with the amount of money needed for each laptop:
37 500 ÷ 2500 = 15
