Mark solved the equation 23x=9 by using the Division Property of Equality to get x=6. Did Mark solve the equation correctly? Explain why or why not.
Answer:
wrong
Step-by-step explanation:
The division property states that when we have an equation in the form [tex]ax=b[/tex], then [tex]x=b/a[/tex](i.e. we "divide" by [tex]a[/tex] on both sides).
So, Mark was supposed to get [tex]x=9/23[/tex], which is not equal to [tex]6[/tex].
So, Mark solved it [tex]\boxed{wrong}[/tex]
No, Mark solve the equation correctly.
because, Mark was supposed to get x = 27/2 , which is not equal to x= 6.
The division property of equality applicable.
The division property of equality is a property that tells us if we divide one side of an equation by a number, we must also divide the other side by the same number so that our equation stays the same. The formula for this property is if a = b, then a / c = b / c.
We have the following information available from the question is:
The equation is:
[tex]\frac{2}{3}x=9[/tex]
It solved by using the Division Property of Equality and get x = 6
If we solved for x: then,
x = 27/2
No, Mark solve the equation correctly.
So, Mark was supposed to get x = 27/2 , which is not equal to x= 6.

Find the slope of the line.
Answer:
The slope is y = x
Step-by-step explanation:
You can find the slope by using the rise over run method with two points.Let's take (1,1) and (2,2). From the first point to the second point, (1,1) goes up one unit and to the right one unit.So the rise over run is 1/1, or 1, which means the slope is 1.
Answer:
m = 1x
Step-by-step explanation:
This is the easiest slope you'll ever have to calculate - if you even need to as it's self explanatory looking at it! Slope = rise/run, thus slope = 1/1 = 1.

Triangle Proportionality TheoremWhat is Triangle Proportionality Theorem?A line that runs perpendicular to one side of a triangle and crosses the other two sides equally splits the two sides.
Use of Triangle Proportionality Theorem to find the sides:Step 1: Consider side NY, NZ, YM, MX
By the theorem,
[tex]\frac{YN}{NZ}=\frac{YM}{MX}[/tex]
[tex]\frac{3}{NZ}=\frac{5}{5}[/tex]
[tex]NZ=3[/tex] units
Step 2: Consider sides YM, YX, NM, ZX
[tex]\frac{YM}{YX} =\frac{NM}{ZX}[/tex]
[tex]\frac{5}{10} =\frac{6}{ZX}[/tex]
[tex]ZX = 12[/tex] units.
Therefore, the values for the sides are NZ = 3 units and XZ = 12 units.

Answer:
I don't know
Step-by-step explanation:
solve for x
r=xy
(Show solving steps please)
Answer:
x=r/y
Step-by-step explanation:
xy together means they are multiplying.
to move y over you do the opposite which is divide by Y on both sides
r/y = xy/y
that way x is next to 1, which we don't have to write
r/y=x
Given the line below.
Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, 2). Use the box provided to submit all of your calculations and final answers.
The slope of that line is -1, so m = -1.
The point you were told to use is (-2,2), so point-slope form starts as:
( y - 2 ) = -1 • ( x - (-2) )
But we'd clean up that x-(-2) to be x+2.
y - 2 = -1 ( x+2 )
