what us the midpoint of A(-8,2) and B(4,-2)
Answer:
(-2 , 2)
Step-by-step explanation:
A(-8 , 2) = (x1 , y1)
B(4 , -2) = (x2 , y2)
midpoint = (x1 + x2/2 , y1 + y2/2)
=(-8 + 4/2 , 2-(-2)/2)
=(-4/2 , 2+2/2)
(-2 , 2)
(3 , 7) = (x1 , y1)
(9 , 2) = (x2 , y2)
distance of PQ = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Solve this problem.
A pair of inline skates that usually sells for $40 is on sale at a 30% discount.
What is the sale price?
Answer:
$28
Step-by-step explanation:
original price = $40
discount = 30%
discount amount = 30% of original price
=30/100 * 40
=$1200/100
=$12
sale price = original price - discount amount
=$40 - $12
=$28

Answer:
A)mean is 1.38 mode is 1.5 median is 1.4
B)mean is 1.775 mode is 1.2 median is 1.75
Step-by-step explanation:
the mean is the average of the numbers added together divided by how many numbers are listed. 1.5+1.2+1.3+1.5+1.4=6.9 6.9 divided by 5 = 1.38
mode is the number that shows up in the list the most.
median is the number that is in the middle of the list of numbers when listed highest to lowest or vice versa.
In the instance of (B) since there were only 4 numbers and could not get exact middle number you take the 2 middle numbers and add them together and divide by 2 to get the average of those 2 numbers

Step-by-step explanation:
Micheal is collecting sea glass from the beach. He begins with 14 pieces in his collection and adds 2 new pieces each day. Determine how may days it will Micheal to have 80 pieces of sea glass in his collection.
Answer:
It would take Micheal 22 days.
Step-by-step explanation:
The end goal is to have 80 and we begin with 14
So, 80 - 14 = 66 pieces left to collect
If he collects 3 per day we'll divide 66 by 3, which equals 22
Therefore it takes him 22 days

Answer:
44 degrees
Step-by-step explanation:
The angles x + 2 and x are complementary; they sum up to 90 degrees.
Thus, x + 2 + x = 90 degrees, or:
2x = 88, or
x = 44.
The value of x is 44 degrees.

Me fui a Cacao Show a comprar bombones blancos y bombones de chocolate negro: Si compro,2 bombones de chocolate negro y 5 de chocolate blanco esa suma nos da $40. Si compro 4 bombones de chocolate negro y 2 de chocolate blanco gasto $26. ¿Cuánto cuesta cada Bombón negro? Y los de chocolate blanco, cúanto cuesta la unidad?
Answer:
Cada bombón negro cuesta $3,125 y cada bombón blanco cuesta $6,75
Step-by-step explanation:
Un sistema de ecuaciones lineales es un conjunto de dos o más ecuaciones de primer grado, en el cual se relacionan dos o más incógnitas.
Resolver un sistema de ecuaciones consiste en buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones. Es decir, resolver un sistema de ecuaciones consiste en encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.
Si compro 2 bombones de chocolate negro y 5 de chocolate blanco, la suma da $40. Si compro 4 bombones de chocolate negro y 2 de chocolate blanco, gasto $26. Siendo:
x: precio de cada bombón de chocolate negroy: precio de cada bombón de chocolate blancoEntonces el sistema de ecuaciones a resolver es:
[tex]\left \{ {{2*x+5*y=40} \atop {4*x+2*y=26}} \right.[/tex]
El método de sustitución consiste en aislar en una ecuación una de las dos incógnitas para sustituirla en la otra ecuación.
Entonces, aislando la variable x de la primer ecuación:
[tex]x=\frac{40-5*y}{2}[/tex]
Sustituyendo en la segunda ecuación:
[tex]4*\frac{40-5*y}{2}+2*y=26[/tex]
Resolviendo:
[tex]\frac{4}{2}* (40-5*y)+2*y=26[/tex]
2* (40-5*y)+2*y=26
2*40- 2*5*y+2*y=26
80- 10*y+2*y=26
- 10*y+2*y=26 -80
-8*y= -54
y= (-54)÷ (-8)
y= 6,75
Reemplazando en la expresión [tex]x=\frac{40-5*y}{2}[/tex], se obtiene:
[tex]x=\frac{40-5*6,75}{2}[/tex]
[tex]x=\frac{40-33,75}{2}[/tex]
[tex]x=\frac{6,25}{2}[/tex]
x= 3,125
Entonces, cada bombón negro cuesta $3,125 y cada bombón blanco cuesta $6,75

Which graph or equation represents a Nonpoportional relationship A B C or D
Answer:
A
Step-by-step explanation:
A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).
The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.
For an equation that represents a proportional relationship, it is written in the form of y = kx
Where, k is the constant of proportionality.
Therefore, the two equations given represents a proportional relationship.

Find the missing side length, and enter your answer in the box below. If necessary, round your answer to 2 decimal places.
Answer:
75
Step-by-step explanation:
87°
Step-by-step explanation:
We know that sum of angles of triangle is 180 ° .
Let as assume that the length of missing side be x.21° + 72° + x = 180°
combine like terms
93 ° + x = 180 °
Subtract 93 ° from each side
93° - 93° + x = 180° - 93°
x = 87 °
Which function's graph has a period of 2?

O B. y = 2 sinax
O C. y = 3cosx
O D. y = -4 sin 2x
Answer:
I BELIEVE ITS C {^_^}
Step-by-step explanation:
The trigonometric function y = 3cos(πx) has a period 2.
What are periodic functions?A periodic function has a range that is determined for a fixed interval and a domain that includes all real number values.
Any function that has a positive real integer p such that f (x + p) = f (x), with all x being real values, is said to be periodic.
a is the function's amplitude.
The function's wavelength is b.
The phase shift of a function is c.
We already know that y = cosx has a 2 period.
The period is calculated as T= 2π/b and if T = 2.
y = 3cosx
2=2π/b
b= 2π/2 = π.

Answer:
14x^3 LCD
(35x+4) / 14x^3
Step-by-step explanation:
5 /2x^2 + 2 / 7x^3
We need to find the least common denominator
2x^2 =2 *x*x
7x^2 = 7*x*x*x
x*x is common so we need to multiply that by 2*7*x
The least common denominator is 2*7*x*x*x = 14 x^3
To add the two, multiply to get the common denominator)
5/2x^2 * (7x/7x) + 2/7x^3 *(2/2)

Answer:
∠SVU = 49°
Step-by-step explanation:
∠SVU is an inscribed angle and arc SU is the arc it intercepts
If you didn't know an inscribed angle is equal to half the measure of its intercepted arc.
Hence ∠SVU = arc SU / 2
if arc SU = 98
Then ∠SVU = 98/2 = 49

ethan invests £500 in the bank for 2 years he earned £40 simple interest
Answer:
Rate = 4%
Step-by-step explanation:
principal = £500
time = 2 years
simple interest = £40
rate = ?
simple interest = PTR / 100
£40 = £500*2*R /100
£40*100 = £1000*R
£4000/£1000 = R
4 % = R

Please, I am begging. I don't understand inverses.
Answer:
0
9
-2
-23
Step-by-step explanation:
a function f(x) defines a y-value for any valid x-value.
that's why it is often written as y = f(x).
the inverse function of an original function just turns the question upside down.
now we want to see for a given y-value of the original function, what was the original x-value to get this y.
therefore we try to transform the original equation that calculates y out of x into one that calculates x out of y.
so, in our example
f(x) = y = -4x - 3
4x + y = -3
4x = -y - 3
x = (-y - 3) / 4
in order to keep the usual terminology with functions also for inverse functions, which are in the end nothing else than functions again, we then name the input variable "x" again, and the result "y".
so, the inverse function is therefore as a function of x
y = (-x - 3) / 4
for x = -3, y = (--3 - 3) / 4 = (3-3) / 4 = 0
when we have y for the inverse function looking for its corresponding x value, then we are investing the inverse function and come back to the original function.
so, for y=-3 of the inverse function that means x=-3 for the inverse inverse (or original) function looking for the y, which is then the x of the inverse function.
f(-3) = -4×-3 - 3 = 12 - 3 = 9 = x of the inverse function.
for x=5 of the inverse function, y = (-5-3)/4 = -8/4 = -2
for y=5 of the inverse function that means x=5 for the inverse inverse (or original) function looking for the y, which is then the x of the inverse function.
f(5) = -4×5 - 3 = -20 - 3 = -23 = x of the inverse function.
