Answer:
J(0,2)
Step-by-step explanation:
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.
The new coordinate of the point j' will be (-8, 12).
What is a transformation of a point?A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.
It is the image of the point which is located in the opposite direction of a given point.
Point j (-8, -12) is reflected over the x-axis. Then the coordinate of the reflected point j' will be
If the coordinate of a point is (x, y) and it is reflected across the x-axis. Then the coordinate of the reflected point will be (x, -y).
Then the new coordinate of the point j' will be (-8, 12).

answer please !!!!please
Answer:
it clicked by it self sorry can't help
Step-by-step explanation:
Answer:
y= -5x+8
Step-by-step explanation:
So frstt you gotta know the form
y= mx+b
y= random Y-coordinate (not useful in this situation)
m= slope
x= random X coordinate (not useful in this situation)
b= y-intercept (the first point of the line that hits the y axis)
So first lets find the slope
sure we can use the slope formula between 2 points but I just did rise over run since this is an easy graph
Rise 5 and go Left 1 so the slope is -5/1 or -5 (negative due to the run going left instead of right plus the line is negative since its falling from left to right)
The y intercept is 8 becuase its the first point where the line crosses the Y axis
ANd thats it!
Plug it in
y= -5x+8

Find.x
Answer:
C. 6√55
Step-by-step explanation:
The triangle given is an isosceles triangle that is divided into two equal parts by a segment.
Thus, we can apply pythagorean theorem to find x.
x = 2 × √(24² - 9²)
x = 2 × √495
x = 2 × √(9 × 55)
x = 2 × 3√55
x = 6√55

Answer:
Option D
Step-by-step explanation:
Since, [tex]\frac{x-y}{x+y}=\frac{2}{7}[/tex]
7(x - y) = 2(x + y)
7x - 7y = 2x + 2y
7x - 2x = 2y + 7y
5x = 9y
[tex]\frac{x}{y}=\frac{9}{5}[/tex]
Since, ΔAED is similar to ΔACB,
Corresponding sides of these triangles will be proportional.
[tex]\frac{BC}{DE}=\frac{AC}{AE}[/tex]
[tex]\frac{x}{y}=\frac{8+AE}{AE}[/tex]
[tex]\frac{9}{5} =\frac{8+AE}{AE}[/tex]
9(AE) = 40 + 5AE
9(AE) - 5(AE) = 40
4(AE) = 40
AE = 10 cm
Therefore, Option D will be the answer.

GIVING BRAINLIEST SYSTEM OF EQUATIONS!!!!!!!!
Answer:
the grid supports the answer
Answer:
Step-by-step explanation:
The given equations are in standard form, first write them in slope-intercept form.
"p" is the variable in the x-axis
"g" is the variable in the y-axis
First equation
[tex]4p+2g=96\\2g=96-4p\\\frac{2g}{2} =\frac{96}{2} -\frac{4p}{2} \\g=-2p+48[/tex]
Second equation
[tex]3p+1g=60\\g=60-3p \\[/tex]
Next you have to determine two points for each equation, the easiest point to determine is the y-intercept, just replace the formula with p=0
First equation
for p=0
[tex]g=-2p+48\\g=-2.0+48\\g=48[/tex]
The first point is (0,48)
For p=10
[tex]g=-2.10+48\\g=-20+48\\g=28[/tex]
The second point is (10,28)
Plot the points and link them with a line.
Second equation
For p=0
[tex]g=-3p+60\\g=-3.0+60\\g=60\\[/tex]
The first point is (0,60)
For p=10
[tex]g=-3.10+60\\g=30\\[/tex]
The second point is (10,30)
Plot both points and link them to determine the line.

m = slope
To know the slope you need only 2 points of the line.
