Brainliest to whoever answers first!!!Z'(5, -7) is the image of Z after a reflection
in the line y=x. What are the coordinates
of Z?
Answer:
I think its Z (-5, 7)
Step-by-step explanation:
Here :)
The coordinates of Z is (7, -5).
Given that, Z'(5, -7) is the image of Z after a reflection in the line y=x.
We need to find the coordinates of Z.
What is the reflection in the line y=x?When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
So, the coordinates of Z become (7, -5).
Therefore, the coordinates of Z is (7, -5).

Hope it helped
pls mark BRAINLIEST
Help me please I am
so confused
Answer:
Step-by-step explanation:
The midpoint between two points is the average of the coordinates.
mp=((x2+x1)/2, (y2+y1)/2)
In this case we are given one end point and the midpoint.
Just look at the x coordinate first.
If the mid x is 8 and the x from j is 10 we have
(10+x)/2=8
10+x=16
x=6, now for the y for j when y=6 and mid y of 5
(6+y)/2=5
6+y=10
y=4
So the coordinates of K are (6,4)

What is XY? .........................
Answer: B i guess
Step-by-step explanation:
The hypotenuse side XY of given right angle at Z is [tex]5\sqrt{2}[/tex].
Given that in triangle XYZ :
∠X=45°
∠Y=45°
XY=5
And right angled at Z, that is, ∠Z=90°.
Since, ∠X=∠Y=45°
Therefore, XZ=YZ=5
Now,
[tex]\sin \theta = \dfrac{hypotenuse}{opposite}[/tex].
Here, θ=45°.
Therefore,
[tex]\sin \theta=\dfrac{5}{XY}\\\\\sin 45\°^=\dfrac{5}{XY}\\\dfrac{1}{\sqrt{2} } =\dfrac{5}{XY}\\\\XY=5\sqrt{2}[/tex]
Thus, the side XY=[tex]5\sqrt{2}[/tex].

Step-by-step explanation:
The reflection line y = x does the following to the coordinates:
(x , y) --> (y , x)
The coordinates swap places.
(5,2) --> (2,5)
(5,1) --> (1,5)
(8,1) --> (1,8)
x+y=14
2x+3y=30
How do I determine which method is used for this and what is it? (Thorough explanation please)
Answer:
x = -18
y = 4
Step-by-step explanation:
x + y = 4
2x + 3y = 30
You can do any math operation to each side of the equal sign as long as you do the same operation to both sides.
change x + y = 4 to x = 4 - y
Now substitute (4 - y) into the second equation, in place of x.
2(4-y) + 3y = 30
multiply the 2(4-y) part:
8 -2y + 3y = 30
simplify:
8 + y = 30
subtract 8 from each side:
y = 22
now substitute the value of y back into the first equation to solve for x:
x + 22 = 4
subtract 22 from both sides:
x = -18
Check:
x + y = 4
22 -18 = 4
4 = 4 (this checks)
2(-18) + 3(22) = 30
-36 + 66 = 30
30 =30 (this checks also)
PS: you could have solved for y first if you had wanted to. The results would be the same.

someone help I don't know this trig question
Answer:
Bill is 9.80 km apart from Concert
Step-by-step explanation:
It's given in the question,
m∠B = 75°
m∠C = 45°
By triangle sum theorem,
m∠A + m∠B + m∠C = 180°
m∠A + 75° + 45° = 180°
m∠A = 180° - 120°
m∠A = 60°
By sine rule,
[tex]\frac{\text{sin}(\angle A)}{BC}=\frac{\text{sin}(\angle C)}{AB}[/tex]
[tex]\frac{\text{sin}(60)}{BC}=\frac{\text{sin}(45)}{8}[/tex]
BC = [tex]\frac{8\text{sin}(60)}{\text{sin}(45)}[/tex]
= 9.80 km
Therefore, Bill is 9.80 km apart from Concert.

What is the solution
-3x + y = 2
y = x + 4
Answer:
to find the solution, we substitute y = x + 4 into the other equation.
-3x + (x + 4) = 2
-3x + x + 4 = 2
-2x = 2 - 4
-2x = -2
x = 1
to find y, we substitute x to the x variable in the y equation.
y = 1 + 4
y = 5
therefore, when combined, it is (1,5).

If f(x) = 11 - 6(x - 8), what is f(-3)?
Answer:
We conclude that:
[tex]f\left(-3\right)=77[/tex]Step-by-step explanation:
Given the function
[tex]f(x) = 11 - 6(x - 8)[/tex]
Important Tip:
In order to determine f(-3), all we need is to substitute x = -3 in the function equationsubstitute x = -3 in the equation
[tex]f(x) = 11 - 6(x - 8)[/tex]
[tex]f(-3) = 11 - 6(-3 - 8)[/tex]
[tex]f\left(-3\right)\:=\:11-\left(-66\right)[/tex]
[tex]f\left(-3\right)\:=\:11+66[/tex] ∵ Apply rule -(-a) = a
[tex]f\left(-3\right)=77[/tex]
Therefore, we conclude that:

How many square inches are in 60 square feet?
5 square inches
72 square inches
720 square inches
8,640 square inches
Answer:
8,640
Step-by-step explanation:
One foot is 12 inches, so a square foot would be 144 inches (12×12 -> l×w) So, you would multiply 60 by 144, and you would get 8,640 square inches.

Step-by-step explanation:
5x + 3y = 6
-3x - 3y = 6
Answer:
(x,y)=(6,-8)
x=6, y=-8
Step-by-step explanation:
There are many was to answer this question, some are substitution and elimination. I am going to use the substitution method.
Your system of equation is 5x+3y=6 and -3x-3y=6
5x+3y=6
-5x -5x
3y=6-5x
Now you substittion the first equation to the sencond one. It will look like:
-3x-(6-5x)=6
-3x-6+5x=6
2x-6=6
+6 +6
2x=12
Divide both sides by 2 and you get
x=6
Now lets substiton x inot the orgianl equation.
-3(6)-3y=6
-18-3y=6
+18 +18
-3y=24
Divide both sides by -3
y=-8
So, the answer is x=6, y=-8
