Answer:
(2.5, -4.5)
Step-by-step explanation:
Reflection in the x-axis changes the sign of the y-coordinate
(x, y) ⇒ (x, -y)
(2.5, 4.5) ⇒ (2.5, -4.5)
please guys help please
Answer:
See attachment for plot
Step-by-step explanation:
The attachment has enough information to solve for only question (4).
Solving (4), we have:
[tex]W = (-1,-1)[/tex]
[tex]X = (4,1)[/tex]
[tex]Y = (4,5)[/tex]
[tex]Z =(1,7)[/tex]
Required
Reflect over the x-axis
When a point (x,y) is reflected over the x-axis, the resulting point is (x,-y)
i.e.
[tex](x,y) => (x,-y)[/tex]
So, we have:
[tex]W = (-1,-1)[/tex] ==> [tex]W' =(-1,1)[/tex]
[tex]X = (4,1)[/tex] ==>[tex]X' = (4,-1)[/tex]
[tex]Y = (4,5)[/tex] ==> [tex]Y' =(4,-5)[/tex]
[tex]Z =(1,7)[/tex] ==> [tex]Z' = (1,-7)[/tex]
So, we plot on a grid, the following points:
[tex]W' =(-1,1)[/tex]
[tex]X' = (4,-1)[/tex]
[tex]Y' =(4,-5)[/tex]
[tex]Z' = (1,-7)[/tex]

Brody created a map of his neighborhood using a scale of 2 inches = 3 blocks. If his street is 9 blocks long, how long will it be on the map?
Answer:
6 inches
Step-by-step explanation:
If 3 blocks equals 2 inches, then we must first find out how many times 3 can fit into 9. We do this by dividing 9 by 3 to get 3. To get your final answer just multiply 2 by 3 and you will get 6 inchs. I hope this helped :0

2. Half of Robert's piece of wire is equal to of Maria's wire. The total length of their wires is 10 feet. How much longer is Robert's wire than Maria's?
Step-by-step explanation:
Given that,
Half of Robert's piece of wire is equal to of Maria's wire i.e.
[tex]\dfrac{R}{2}=M[/tex] ....(1)
Total length of the wires = 10 feet
ATQ,
[tex]R+M=10[/tex] ....(2)
Use equation (1) in (2).
[tex]R+\dfrac{R}{2}=10\\\\\dfrac{3R}{2}=10\\\\R=\dfrac{20}{3}\\\\R=6.67\ ft[/tex]
So,
[tex]M=\dfrac{6.67}{2}\\\\M=3.33\ ft[/tex]
Hence, this is the required solution.

What is the value of the expression 6 3/4 (- 11.5)?
GO3
Answer:
-77.625
Step-by-step explanation:
How to find
To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations. Therefore, the value of the expression 6 3/4 (- 11.5) is -77.625.
solve 4x-5/5=3
thankyou
Answer:
x = 1
Step-by-step explanation:
4x - 5/5 = 3
4x - 1 = 3
add 1 to each side of the equation:
4x = 4
divide both sides by 4:
x = 1
Answer:
4x=3+5/5

Multiply: (9-8i)(-6,-15i)
Answer:
(9-8i)(-6,-15i) = -174 + 183 i
Step-by-step explanation:
Explanation:-
Given that the complex numbers
(9-8i)(-6,-15i)
multiply ( 9-8i ) ( -6 -15i)
= -54 - 9(-15 i) + 48 i + 120(i)²
= -54 + 135 i + 48 i - 120
= -174 + 183i
Final answer:-
(9-8i)(-6,-15i) = -174 + 183 i
Solve for u.
127-u = 258
24 =
What is u?
127 - u = 258
-u = 258 - 127
-u = 131 | : (-1)
u = -131
Answer:
127-u=258
258-127=131
a circle passes through the points o(0,0), a(8,4) and b(6,6). show that oa is a diameter of the circle and find the equation of the circle
9514 1404 393
Answer:
(x -4)² +(y -2)² = 20
Step-by-step explanation:
The circle is the circumcircle of triangle OAB. Then OA will be a diameter if angle OBA is a right angle. We can check that by looking at the slopes of AB and BA.
B-O = (6, 6)-(0, 0) = (6, 6) ⇒ slope = Δy/Δx = 6/6 = 1
A-B = (8, 4) -(6, 6) = (2, -2) ⇒ slope = -2/2 = -1
These slopes have a product of -1, so OB ⊥ BA. The hypotenuse (OA) of ΔOBA is the diameter of the circle.
Then the midpoint of the hypotenuse is the center of the circle.
C = (O +A)/2 = ((0, 0) +(8, 4))/2 = (4, 2)
The equation is ...
(x -h)² +(y -k)² = r² . . . . . circle with center (h, k) and radius r
The radius is the distance from O to C, so is ...
r² = 4² +2² = 20
and the equation of the circle is ...
(x -4)² +(y -2)² = 20 . . . . equation of the circle
What's the circumference of a
circle with a diameter of 9 inches?
Use 3.14 for n.
Answer:
28.26 in
Step-by-step explanation:
Radius = (1/2) diameter
Radius = (1/2)(9)
Radius = 4.5 in
Circumference = 2πr
Circumference = 2(3.14)(4.5)
Circumference = 28.26 in
