Chrissie says that the equation of the line shown on the graph is y= 1/2x -5. George says that the equation of the line is y= 1/2x + 5. Which student is correct? Explain.
Answer:
wheres the graph which is provided by the question?
Step-by-step explanation:
The y-intercept of George's equation is positive. Then George's equation is correct.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Chrissie says that the equation of the line shown on the graph is y = 1/2x -5. George says that the equation of the line is y = 1/2x + 5.
From the graph, the y-intercept of George's equation is positive then George's equation is correct.

Answer: All Real Number
Step-by-step explanation:
This is a system of equation, and generally, there are three ways to solve:
eliminationsubstitutionaugmented matrixHere, we are going to use elimination
------------------------------------------------------------------------------------
Given
-2x-y=1
-6x=3y+3
Put them in the same order
-2x-y=1
-6x-3y=3
Multiply 3 on both sides for the first equation
-6x-3y=3
-6x-3y=3
We subtract the first equation from the second equation
0=0
The answer will be All Real Numbers, which means any real number will fit this equation. In the graphing method, these two equations will overlap each other.

Answer and Step-by-step explanation:
For this triangle, to find x, we will use the cosine trigonometric function.
cosine functions look like this:
[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]
(The weird looking symbol is called theta, and represents an angle measurement)
Plug in the values into the equation.
cos(42) = [tex]\frac{x}{15}[/tex]
Multiply both sides by 15.
15(cos(42)) = x
Plug into a calculator.

Use the graph of the polynomial
function to find the factored form of
its related polynomial. Assume it
has no constant factor
Answer:
The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].
Step-by-step explanation:
According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:
[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)
Where:
[tex]x[/tex] - Independent variable.
[tex]y[/tex] - Dependent variable.
[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.
We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:
[tex]a^{2}-b+c = 0[/tex] (2)
[tex]c = -2[/tex] (3)
[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)
The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:
[tex]y = (x-2)\cdot (x+1)[/tex] (5)

Solve For X. Solve similar triangles (advanced)
The value of x in the given similar triangles ADB and BCE is 4.5.
To solve for x in the given similar triangles ADB and BCE, we can set up the proportion of corresponding sides:
In triangle ADB, we have:
AB/BD = x/DE
Substitute the given values:
3/4 = x/6
Now, cross-multiply and solve for x:
3 * 6 = 4x
18 = 4x
x = 18/4
x = 4.5
So, the value of x is 4.5.
