Answer:
Step-by-step explanation:
First get the answer to -3n - 4 = 2
-3n - 4 + 4 = 2 + 4
-3n = 6
n = 6/-3
n = -2
That answer is the only one that is permitted. It is the only one that completely satisfies the equation.
Now when you do the inequality, look what happens.
-3n - 4 < 2 Add 4 to both sides.
-3n-4+ 4 < 2+4
-3n < 6 Now there are a bunch of ways (2) to solve this.
No matter which way you do it, the arrow will change.
-3n/-3 > 6/-3
n > - 2
That means that any number that is greater than - 2 will satisfy the inequality.
So n = 0 will work. Even n = - 1 will work. Anything bigger than -2 will work. The equation does not provide that kind of latitude.

The standard form of ellipse with vertical major axis and center at the origin is:
x^2/b^2+y^2/a^2=1, a>b
2a=length of the major axis=28
a=14
a^2=196
2b=length of minor axis=20
b=10
b^2=100
x^2/196+y^2/100=1
making y the subject we get
y=5/7(196-x²)^0.5
Answer:
[11,-13]
Step-by-step explanation:
Let P be the point between A(3,-5) and B(13,-15) where segment AP = 
th of segment AB.
Therefore, point P divides the line AB in a 4 : 1 ratio internally.
Hence, the coordinates of point P will be ![[\frac{4\times 13+ 1 \times 3}{4+1} , \frac{4(-15)+ 1(-5)}{4+1} ]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B4%5Ctimes%2013%2B%201%20%5Ctimes%203%7D%7B4%2B1%7D%20%2C%20%5Cfrac%7B4%28-15%29%2B%201%28-5%29%7D%7B4%2B1%7D%20%5D)
= [11,-13] (Answer)
We know that If A
and B
are two different point and point P(h,k) divides line AB in the ratio m : n internally, then
(h,k) ≡
