AB has endpoint A(-2,3) and midpoint M(4,6).
Find the coordinates (x, y) of B.
Answer:
B = (10, 9 )
Step-by-step explanation:
Using the midpoint formula
M = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
with (x₁, y₁ ) = A(- 2, 3) and (x₂, y₂ ) = B(x, y) , then equate to the x and y coordinates of the midpoint M(4, 6)
[tex]\frac{-2+x}{2}[/tex] = 4 ( multiply both sides by 2 )
- 2 + x = 8 ( add 2 to both sides )
x = 10
and
[tex]\frac{3+y}{2}[/tex] = 6 ( multiply both sides by 2 )
3 + y = 12 ( subtract 3 from both sides )
y = 9
Then B = (10, 9 )

Find the length of the third side. If necessary, round to the nearest tenth.
Answer:
hi answer is 69 solved by Pythagoras theorem
Answer:
7.94
Step-by-step explanation:
We can use the Pythagorean theorem for this
since we know two legs, and not the hypotenuse, we should solve for that
the pythagorean theorem states that a squared + b squared is equal to c squared. C, is the hypotenuse, sos let’s plug it in
16 + 47 = c squared
63 = c squared.
square root 63 = c
c is equal to 7. 94 rounded to the nearest hundered

Answer:
y - 24 = - 7(x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 24) and (x₂, y₂ ) = (7, - 53)
m = [tex]\frac{-53-24}{7+4}[/tex] = [tex]\frac{-77}{11}[/tex] = - 7
Using m = - 7 and (a, b) = (- 4, 24 ) , then
y - 24 = - 7(x - (- 4)), that is
y - 24 = - 7(x + 4)

Bridget drew ΔYZ and Δ′ ′ ′ on a coordinate plane, as shown below.
Which statement about the relationship between ΔYZ and Δ′ ′ ′ is true?
A: Δ′ ′ ′ is NOT a translation of ΔXYZ because not all points contained in Δ′ ′ ′ have negative x-coordinates.
B: Δ′ ′ ′ is a translation of ΔXYZ because their corresponding sides are parallel.
C: Δ′ ′ ′ is a translation of ΔXYZ because all points in Δ′ ′ ′ are the same distance and direction from the corresponding points in ΔXYZ.
D: Δ′ ′ ′ is NOT a translation of ΔXYZ because the y-coordinate of Point is not the same as the y-coordinate of point ′.
Answer:
The statement that is true about the relationship between ΔXYZ and ΔX'Y'Z' is option "C"
C. ΔX'Y'Z' is a translation of ΔXYZ because all points in ΔX'Y'Z' are the same distance and direction from the corresponding points in ΔXYZ
Step-by-step explanation:
The triangles Bridget drew are;
ΔXYZ and ΔX'Y'Z'
The coordinates of ΔXYZ = X(-5, 7), Y(-9, 2), Z(-3, 2)
The coordinates of ΔX'Y'Z' = X'(1, 2), Y'(-3, -3), Z'(3, -3)
From the coordinates we have;
The x-coordinates of ΔX'Y'Z' = The x-coordinates of ΔXYZ + 6
The y-coordinates of ΔX'Y'Z' = The y-coordinates of ΔXYZ - 5
Therefore, the translation that gives ΔX'Y'Z' from ΔXYZ = T₆, ₋₅
Therefore;
1) ΔX'Y'Z' is obtained from ΔXYZ by a translation as the points in ΔX'Y'Z' are obtained from ΔXYZ by adding the same value to the x-coordinates of the points on ΔXYZ and subtracting the same value to the y-coordinates of the points on ΔXYZ, such that the points in triangle ΔX'Y'Z' are equidistant from and on the same side relative to the corresponding points on ΔXYZ
2) Given that triangle ΔXYZ and ΔX'Y'Z' are not rotated or reflected, we have that the corresponding sides of ΔXYZ and ΔX'Y'Z' are parallel
The correct options are therefore option "C" and and the option "B" is only partially correct because the sides can be parallel but do not have the same size.

Answer:
1) $575
2) They'll markup the price by $3,240. After the markup, the retail price is $15,240
Step-by-step explanation:
1)
6% = 0.06
3750(0.06) = 225
225 + 350 = 575
2)
27% = 0.27
12000(0.27) = 3240
Profit = 3240
Price for retailer = Cost Price + Profit
Price for retailer = 12000 + 3240
Price for retailer = 15,240

En un hotel hay 4 pisos y en cada piso hay 4 habitaciones. Si en cada habitación hay 4 personas y cada persona hace 4 llamadas telefónicas, ¿Cuántas llamadas se hacen en total?
Respuesta:
Se realizaron 256 llamadas telefónicas
Explicación paso a paso:
Número de pisos = 4
Número de habitaciones por piso = 4
Número de personas por habitación = 4
Número de llamadas telefónicas por persona = 4
Número total de llamadas telefónicas realizadas;
Número total de personas alojadas en el hotel:
Número de pisos * número de habitaciones por piso * número de personas por habitación
(4 * 4 * 4) = 64 personas
Número de llamadas telefónicas realizadas:
64 personas * 4 = 256 llamadas telefónicas
(1)/(4p)(x-h)^(2)+k=0
Multiply the equation by 4p. Explain how different values of k affect the number of zeros of the polynomial. Consider k > 0, k = 0, and k < 0. Assume p > 0.
Answer:
Step-by-step explanation:
Given p>0, multiply the equation by 4p: (1/4p)*(x-h)^(2)+k=0
(x-h)^2+4kp = 0
k>0
4kp>0
(x-h)^2 = -4kp
So x has imaginary roots only. There is no real zeros of the polynomial.
k=0
4kp=0
(x-h)^2 = 0
x=h
So x has one real root and the polynomial has one zero
k<0
4kp<0
(x-h)^2 = -4kp
So x has two real roots and the polynomial has two real zeros.
Answer:
Step-by-step explanation:
Assume that and multiply the equation by 4p. Then you obtain the equation (x-h)^2+4pk=0.
1) If k>0, then 4pk>0 and the equation does not have real solutions and there is no zero.
2) If k=0, then 4pk=0 and . There is one solution x=h and there is one zero.
2) If k<0, then 4pk<0 and the equation has two different solutions and there are two zeros.
