Draw the graph of the equation 2x - y = 10.
Answers
Answer:
see attached
Step-by-step explanation:
The graph of a linear equation can be drawn using any of several methods. Here, we are given the equation in standard form. We notice that the variable coefficients are both divisors of the constant, which means the x- and y-intercepts will be integer values. It will be convenient to draw the graph using those points.
__
The x-intercept is the x-value when y = 0.
2x -0 = 10
x = 10/2 = 5 . . . . . . (5, 0) is a point on the line
__
The y-intercept is the y-value when x = 0.
0 -y = 10
y = -10 . . . . . . . (0, -10) is a point on the line
__
The graph can be drawn by plotting these points and drawing the line through them. This is shown in the attachment.

What are the solutions to the equation?
x²-12x+36=4
Enter your answers in the boxes.
x1 =
x2=
Answers
The roots of this equation equation are:
x1 = 4
x2 = 8
This sentence given in the statement of this question is: Equation of the Second Degree. There are a few ways to solve it, but let's calculate by the factorization method.
Equation given: x² - 12x + 36 = 4
First, let's multiply the 12 and 36 term into factors (factoring):x² - 12x + 36 = 4
12x ➯ 2x . x6
36 ➯ 6²
x² - 2x . x6 + 6²
( x - 6 )² = 4
Now we remove the parentheses and we will transform the exponent 2 into the square root of its original number:( x - 6 )² = 4
x - 6 = ±√4
x - 6 = ±2
We will organize the equation in two forms, being: positive and negative:x - 6 = ±2
x - 6 = -2
x - 6 = +2
Finally, let's calculate the first degree equation:x - 6 = -2
x = -2 + 6
x = 4
x - 6 = +2
x = 2 + 6
x = 8
Therefore, the correct results of this equation, will be:
x1 = 4
x2 = 8

Answers
The statement about the graphs is true is: Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.
Statement about the graph that is trueGraph curve is above the horizontal axis.
Let determine the area under the curve using this formula
Base of left and right triangle
Left
Base = -3 - (-5)
Base= 2
Right
Base= 3 - (-3)
Base= 6
Right and left height
Height= 0.25
Hence:
Total area=(base× height)/2
Total area=[ (2×0.25)/2] + (6×0.25)/2
Total area=0.25+0.75
Total area=1
Therefore Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1.

Hi Student!
Looking at the question, we are given a fraction that has a pi symbol. We learn in trigonometry that a whole circle is made up of 2 * pi and we know that a circle is 360 degrees. That means that just having pi means that we have 180 degrees.
Therefore, looking at the fraction that was given to us, we can basically interpret it as 180 degrees / 4. That will give us a solution of 45 degrees which is our final answer.
Answer:
