Where the above right triangle is given, note that the value of x when rounded to the nearest tenth is 19.2.
What is a right triangle?
A right triangle is a triangle with one angle measuring 90°, forming a perpendicular side.
In this case,the base is 9 and the height is 17. Using the Pythagorean theorem, we can calculate the length of the hypotenuse as follows:
x² = 9² + 17²
x²= 81 + 289
x² = 370
To find the value of x, we take the square root of both sides -
x = √370
x = 19.2353840617
x ≈ 19.2 (rounded to the nearest tenth)

System of Equations
Solve the following system of equations:
11x + 22y = 88
x = 10 - 3y [2]
By the substitution method.
We can divide the first equation by 11:
x + 2y = 8 [1]
Substitute x from [2] into [1]:
10 - 3y + 2y = 8
Simplifying:
10 - y = 8
Subtracting 10:
-y = -2
Multiplying by -1:
y = 2
From [2]:
x = 10 - 3y
x = 10 - 3*2 = 4
Solution: (4,2)

Orange Street has a y-intercept of -4 and a slope of 4/5
Write out this equation as y = mx + b
Answers
Answer:
y = 4/5x - 4
Step-by-step explanation:
Slope intercept is [ y = mx + b ] where m = slope and b = y-intercept. We are already given both so we can fill it in.
y = 4/5x - 4
Best of Luck!
Answer:
Orange Street has a (b=)y-intercept of -4 and a (m=)slope of 4/5
Therefore, m=4/5 and b= -4
y = mx+b
y = 4/5x+(-4)
y = 4/5x - 4 is the right answer.

Jk =5x+17,KL = x -1,JL=7x-9 find a range of possible values for x
Answers
Value of x in the triangle will have the range 9 < x < 25 .
Given, JK = 5x+17, KL = x -1, JL = 7x-9
According to triangle property,
Sum of any two side of the triangle is greater than the third side.
JK = 5x+17
KL = x -1
JL = 7x-9
Case 1:
∴ JK +KL > JL
5x+17 + x -1 > 7x-9
25 > x
Case 2:
KL + JL > JK
x -1 + 7x-9 > 5x+17
x > 9
Case 3 :
JK + JL > KL
5x+17 + 7x-9 > x -1
x > -9/11
Therefore the range of possible values of x : 9 < x < 25 .

PLATO Course Math 8, Unit Activity Transformations: Preston says the sequence of transformations that maps triangle ABC onto triangle DEF is: rotate it 180 degrees about the origin, and then translate it up 7 units.
Chanel says the sequence of transformations that maps triangle ABC onto triangle DEF is: reflect it across the x-axis, then reflect it across the y-axis, and then translate it up 6 units and left 1 unit.
Complete a table to find the rule for the rotation, the coordinates of triangle ABC, and the coordinates of the rotated image, triangle A′B′C′. Please put the letter before the coordinates.
Answers
Transformation involves changing the position of a shape.
The transformation rule is: [tex]\mathbf{(x,y) \to (-x - 1,-y + 6)}[/tex]
From the graph, we have the following points
[tex]\mathbf{A = (-4,5)}[/tex]
[tex]\mathbf{B = (-3,1)}[/tex]
[tex]\mathbf{C = (-5,2)}[/tex]
First, triangle ABC is reflected across the x and y axes.
So, we have:
[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]
Next, the points are shifted up by 6 units, and left by 1 unit.
So, we have:
[tex]\mathbf{(x,y) \to (-x - 1,-y + 6)}[/tex]
Apply the above transformation rule on ABC, we have:
[tex]\mathbf{C = (4 - 1,-5 + 6) = (3,1)}[/tex]
[tex]\mathbf{D = (3 - 1,-1 + 6) = (2,5)}[/tex]
[tex]\mathbf{E = (5 - 1,-2 + 6) = (4,4)}[/tex]
Hence, the transformation rule is: [tex]\mathbf{(x,y) \to (-x - 1,-y + 6)}[/tex]
And the image of the transformation are:
[tex]\mathbf{D = (3,1)}[/tex] [tex]\mathbf{E = (2,5)}[/tex] [tex]\mathbf{F = (4,4)}[/tex]

Write an equation of the line graphed below.
Answers
Answer:
y=1/2x+3
Step-by-step explanation:
So the slope formula is y=mx+b. Where mx is the slope and b is the y-intercept. In this case our slope is 1/2 because we rise by one unit and run by 2 units. The y-intercept in this case is 3 because on the y axis the line intersects over 3.
Hopefully that helped :).
