Answer:

Part 9) x=5  

Part 10) x=-9  

Step-by-step explanation:

we know that

The <u><em>Midpoint Theorem</em></u> states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

Part 9) we know that

Point Q is the midpoint segment XY (QY=QX)

Point R is the midpoint segment XW (RW=RX)

Applying the Midpoint Theorem

RQ is parallel to WY

and

RQ=\frac{1}{2}WY  

we have

RQ=2x-3\\WY=x+9

substitute

2x-3=\frac{1}{2}(x+9)  

solve for x                  

4x-6=(x+9)          

4x-x=9+6

3x=15  

x=5  

Part 10) we know that

Point B is the midpoint segment TS (BS=BT)

Point C is the midpoint segment RS (CS=CR)

Applying the Midpoint Theorem

BC is parallel to TR

and

BC=\frac{1}{2}TR  

we have

BC=x+19\\TR=x+29

substitute

x+19=\frac{1}{2}(x+29)  

solve for x

2x+38=(x+29)  

2x-x=29-38          

x=-9

X=0 because when you have something to the power of zero your answer is 1.
x=0 since 1 to the power of zero equals 1.

Find the slope of the line passing through the points (1,-5) and (4,1).
e-lub [12.9K]
<h3>Answer:</h3><h3>The equation for the slope of a line, given two coordinate points, (x1,y1) , (x2,y2), is (y2-y1)/(x2-x1)  </h3><h3>  So we get slope = (1-(-5)) / (4-1)  = 6/3 = 2</h3><h3>A is your correct answer.</h3>

Hope this helps! please consider marking my answer the brainliest :)

Plsss help me graph this!!! Attached is the question
e-lub [12.9K]

The graph is a straight line graph with a slope of -1/2

Equation of a line in point-slope form

The equation of a line in point slope form is expressed as:

y - y₁ = m(x - x₁)

Given the following parameters

Point = (-2, 3)

Slope = -1/2

Substitute the given parameters into the formula

y-3 = -1/2(x-(-2))

y-3 = -1/2(x+2)

Write in slope-intercept form

2(y-3) = -(x+2)

2y-2(3) = -x -2

2y - 6 = -x -2

2y = -x + 4

y = -1/2x + 2

The graph of the equation is as shown below

What is the value of the expression
prisoha [69]

Answer:

6

Step-by-step explanation:

Follow the PEMDAS rule.

Parentheses

Exponent

Multiplication

Division

Addition

Subtraction

By following that rule, you know that you have to take care of the exponent first. 1/2 to the fourth power is 1/16. Then the next step in pemdas is to multiply that with 48, which is 3. The you subtract 3 from 9.

Hope this helps <3
