Answer:
[tex]= \frac{-2(x-6)}{(x+4)(x-4)}[/tex]
Step-by-step explanation:
Given the expression;
[tex]\frac{x}{x^2-16} -\frac{3}{x-4}[/tex]
According to difference of two square;
x² - 16 = x²-4² = (x+4)(x-4)
Substitute;
[tex]\frac{x}{(x+4)(x-4)} - \frac{3}{x - 4}\\[/tex]
Find the LCM
[tex]= \frac{x-3(x+4)}{(x+4)(x-4)} \\= \frac{x-3x-12}{(x+4)(x-4)}\\= \frac{-2x-12}{(x+4)(x-4)}\\= \frac{-2(x-6)}{(x+4)(x-4)}[/tex]

10
Step-by-step explanation:
10x²-14x+k = 0
x1 = sin a
x2= cos a
x1+x2 ≤ 2
x1. x2 ≤ 1 => k/10 ≤ 1
k ≤ 10

A triangle has sides with lengths of 8 kilometers, 13 kilometers, and 16
kilometers. Is it a right triangle?
Answers
We can prove by using Pythagoras theorem
Let the longest length be hypotenuse and shortest length be base now,
h^2=p^2+b^2
16^2=13^2+8^2
256=169+64
246=233
Hence it is not equal with hypotenuse
In right triangle the sum of the squares of two short sides should be equal to hypotenuse

Workers load 5 identical large crates and 3 identical small crates onto a freight elevator. The crates have a combined weight of 1375 pounds. Later
that day, the workers load 3 more identical large crates and 6 more identical small crates onto the freight elevator. These crates have a combined
weight of 1350 pounds.
What is the weight of each crate?
A. Each large crate weighs 185 pounds, and each small crate weighs 150 pounds.
B. Each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
C. Each large crate weighs 225 pounds, and each small crate weighs 112.5 pounds.
D. Each large crate weighs 250 pounds, and each small crate weighs 100 pounds.
Answers
Answer:
B. Each large crate weighs 200 pounds, and each small crate weighs 125 pounds.
Step-by-step explanation:
Let L be the weight of the large crate and S the weight of the small crate.
Given that 5 identical large crates and 3 identical small crates have a combined weight of 1375 pounds,
5L + 3S = 1375 (1)
Also, in the second loading 3 identical large crates and 6 identical small crates have a combined weight of 1350 pounds,
3L + 6S = 1350 (2)
multiplying equation (1) by 2 and (2) by 1, we have
5L + 3S = 1375 (1) × 2
3L + 6S = 1350 (2) × 1
10L + 6S = 2750 (3)
3L + 6S = 1350 (4)
Subtracting (4) from (3), we have
7L = 1400
dividing through by 7, we have
L = 1400/7
L = 200
Substituting L = 200 into (1), we have
5L + 3S = 1375 (1)
5(200) + 3S = 1375 (1)
1000 + 3S = 1375
3S = 1375 - 1000
3S = 375
dividing through by 3, we have
S = 375/3
S = 125
So, each large crate weighs 200 pounds, and each small crate weighs 125 pounds.

Two poin on this line are (-2, 3) and (0, -3). Both points are formed where grid lines meet precisely.
The change in x as we go from (-2, 3) to (0, -3) is +2 and the change in y is -6. Thus, the slope of the line shown is m = rise/run = -6/2, or m = -3.

What does the constant 0.2 reveal about the rate of change of the quantity?
the rate percentage
Answers
Answer:
80% decrease in the quantity over 7 days
Step-by-step explanation:
Given data
We have the function
f (t) = 310(0.2)24
the above function is similar to the exponential function
f (t) = P(1±r)^t
Now the value 0.2
This means that there is 80% decrease in the quantity over 7 days

Plane J and Line KF intersect at what point?
Answers
Answer:
what are the answers if you want help
The plane J and line KF intersect at point K on the plane.
What is a plane?A plane is a two-dimensional doubly ruled surface spanned by two linearly independent vectors. A plane extends infinitely in two dimensions. It has no thickness.
What is a line?A line is a one-dimensional figure, which has length but no width. It is determined by two points in a two-dimensional plane. A line is made of a set of points which is extended in opposite directions infinitely.
For the given situation,
The diagram shows a plane J and some line segments.
If a line and a plane have only one point in common, then the line intersects the plane.
From the diagram, it is clearly seen that the plane J and line KF intersect at point K on the plane.
Hence we can conclude that the plane J and line KF intersect at point K on the plane.
