Step-by-step explanation:
Answer:
x=7.5
Step-by-step explanation:
3(x+4.5)=36
Distribute
3x+13.5=36
36-13.5=22.5
3x=22.5
22.5/3=7.5
x=7.5
Answer:
60 degrees
Step-by-step explanation:
Every Triangle has an angle of 180degrees
so if we add all of the written angles which is 25 + 35 + 60 = 120
we take 180 degrees and subtract it with the previous answer (120)
180 - 120 = 60
Thereforeitis60degrees
Answer:
answer is 60
Step-by-step explanation:
because if the angle is 60 degrees anywhere in the triangle means its an equilateral triangle making all the angles 60 degrees
Where else have you heard the term model? How is that meaning of the word different from or the same as the meaning we use in algebra? good answers only
Answer:
The definition of a model is a specific design of a product or a person who displays clothes, poses for an artist. An example of a model is a hatch back version of a car. An example of a model is a woman who wears a designer's clothes to show them to potential buyers at a fashion show. Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables.
Step-by-step explanation:
Answer:
x = 9
Step-by-step explanation:
The slope would be 6
Y -int would be 16
Through this we can find out that the slope-intercept form is
y = 6x + 16
insert 70 into y
solve for x
70 = 6x + 16
54 = 6x
9 = x
The equation of the line is y = 4x + 18 and the value of x is 13
From the question, we have the following parameters that can be used in our computation:
The graph
A linear equation is represented as
y = mx + c
Using the points, we have
m + c = 22
4m + c = 40
When evaluated, we have
3m = 12
m = 4
So, we have
4 + c = 22
c = 18
Next, we have
y = 4x + 18
When y = 70, we have
4x + 18 = 70
Evaluate
x = 13
Hence, the value of x is 13

3x+2y=14
2x-4y=4
6x+4y=28
2x-4y=4
8x = 32
x = 4
2y = 14 - 12 = 2
y = 1
(x , y) = (4 , 1)
Question:How can check your solution by writing the system as a matrix equation and using the inverse matrix?.
To check the solution, represent the system of equations as a matrix equation, find the inverse of the coefficient matrix, and multiply both sides of the equation by the inverse.
To check the solution by writing the system as a matrix equation and using the inverse matrix, we need to represent the system of equations as a matrix equation. Let's consider the given system of equations:
3x + 2y = 14
2x - 4y = 4
To do this, we can write the coefficients and constants of the system of equations as matrices:
[3 2] [x] = [14]
[2 -4] [y] = [4]
Now, we can write the system of equations as a matrix equation: AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix.
Next, we need to find the inverse of matrix A. If the inverse exists, we can multiply both sides of the matrix equation by the inverse of A to find the solution for X.
If we find the inverse of A and multiply both sides of the equation by the inverse, we get:
X = A-1B
Substituting the values of A-1 and B, we can find X, which represents the solution to the system of equations. Therefore, we can check our solution by writing the system as a matrix equation and using the inverse matrix.
