Answer:
A(-5,9)
Step-by-step explanation:
Let A(a,b)
Since M is the midpoint then of A(a,b) and B(3,-5) then
M( (a+3)/2 , (b-5)/2)
But it is given that M(-1,2)
So (a+3)/2 = -1 which implies a=-5
and (b-5)/2=2 which implies b=9.
Therefore A(-5,9)
Kelly and Greta are asked to write an equation for the scenario below.
“One person was able to plant 4 trees in the same amount of time that 5 people working together were able to plant 20 trees.”
The girls agree that x represents the number of people working and y represents the number of trees planted. Kelly wrote the equation y = one-fourth x, and Greta wrote the equation y = 4 x. Which person is correct, and why?
Answer:
y=4x
Step-by-step explanation:
Cuz in short, if x is one, y is four, if x is 5, y is 20
Thereford only y=4x is suitable
Answer:
Greta is correct.
Step-by-step explanation:
The variable that is lower in each scenario is the variable that should have a coefficient (unless there are fractions). Greta's equation makes sense because it's saying that in order for the # of trees to = the # of people, you need to multiply x by 4, or 4x.
Un cantante subió una publicación la semana pasada en una red social, obtuvo 21 751 "me gusta" y 83 464 "me encanta" por parte de sus fans. Sise sabe que 57 329 de los que participaron en la publicación eran del sexo femenino, ¿cuántas personas eran del sexo masculino? *
A. 46 786 B. 47 886
C. 57 896
D. 57 96
Tenemos que resolver un ejercicio algebraico.
Veremos que la opción correcta es B: 47,886
Lo que sabemos es:
21,751 fans pusieron "me gusta"
83,464 pusieron "me encanta"
Asumimos que cada fan puede usar una sola de esas dos cosas.
Entonces el número total de fans es:
21,751 + 83,464 = 105,215
Tambien sabemos que entre los fans, hay 57,329 mujeres.
Entonces el resto serán hombres:
105,215 - 57,329 = 47,886
Podemos concluir que hay 47,886 hombres, por lo que la opción correcta es B.

Find the Circumference and Area of a circle with the information provided:
D-20ft
R=10ft
Answer:
Circumference, C = 62.8 ft
Area, A = 314 ft²
Step-by-step explanation:
where π = 3.14
Circumference, C = 2π(r)
= 2π(10ft)
= 20π ft
= 62.8 ft
Area, A = π(r²)
= π(10ft)²
= 100π ft²
= 314.1593654 ft²
= 314 ft²

the total cost of a laptop computer is $1278.24. The local sales tax rate is 7.6% what is the retail price?
Answer:
x = 1187.96
Step-by-step explanation:
Let x = price before tax
tax = x* 7.6%
tax = .076x
The cost of the computer is price before tax plus tax
cost = x + .076x
cost = 1.076x
1278.24 = 1.076x
Divide each side by 1.076
1278.24/1.076 = 1.076x/1.076
x=1187.9553
Rounding to the nearest cent
x = 1187.96

Evaluate the limit of sequence at infinity.
[tex] \displaystyle \large{ \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} }[/tex]
Please show your work too. Thanks!
Answer:
[tex]\displaystyle \frac{ 1 }{3} [/tex]
Step-by-step explanation:
we would like to compute the following limit:
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} [/tex]
if we compute the limit from numerator to denominator directly,we'd end up with
[tex] \dfrac{ \infty }{ \infty } [/tex]
which is an indeterminate form so we must do it in a different way. well to compute this limit,we can consider factoring method . notice that we can factor the numerator and that yields
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{ {n}^{2} ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]
remember that ,
[tex] \sqrt{ab} \implies \sqrt{a} \sqrt{b} [/tex]thus we acquire:
[tex]\displaystyle \lim_{n \to \infty } \frac{ {n} \sqrt{ ( 4 {}^{} + \frac{3}{n} )} }{6n} [/tex]
reduce fraction:
[tex]\displaystyle \lim_{n \to \infty } \frac{ {} \sqrt{ 4 {}^{} + \frac{3}{n} } }{6} [/tex]
as n approaches to ∞ ,3/n approaches to 0 which yields:
[tex]\displaystyle \frac{ \sqrt{ 4 {}^{} } }{6} [/tex]
simplify square root:
[tex]\displaystyle \frac{ 2 }{6} [/tex]
reduce fraction:
[tex]\displaystyle \frac{ 1 }{3} [/tex]
hence,
[tex]\displaystyle \lim_{n \to \infty } \frac{ \sqrt{4 {n}^{2} + 3n } }{6n} = \boxed{ \frac{1}{3} }[/tex]
and we're done!

Answer:
the slopes is the change in y on change in x
hence the slopes is -6
The slope of the linear function given is -6.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given is a table which contains the x values and corresponding y values for a linear function.
Slope of a linear function is constant.
If we have two points (x, y) and (x', y') on the graph,
Slope = (y' - y) / (x' - x)
Consider two points from the table, (-1, 2) and (0, -4).
Slope = (-4 - 2) / (0 - -1) = -6 / 1 = -6
Hence the slope of the function given is -6.

If the difference between two numbers is odd,
then the two numbers are both odd.
Step-by-step explanation:
let's say, 7 - 4 = 3
that contradicts the statement that both numbers are odd.
no, they are 7, 4, with 4 being even (and not odd).
in fact, as with sums and subtractions in general, it requires an odd and an even number to produce an odd result.
odd with odd always delivers an even result. as does even with even.

Can someone explain how 8.75 multiplied by 0.8 is 7??? It just don't make sense... I don't see why the number got smaller instead of bigger.....
Answer:
80% of 8.75=7. I'm pretty sure this is the reason.
Answer:
It's because of the decimal of .8
Step-by-step explanation:
It can be confusing but since its not a whole number when you multiply with a whole number gets smaller instead of bigger. So the whole number basically has to give some of it to the decimal so, that the outcome can be a whole number.
Sorry, if this isn't the best!
