Collinear point are the point which lie on the same straight line.

Let us take an example of the sitting arrangements of students in a classroom.

The students sitting in a desk in a row are collinear. Let us suppose that 3 students sit in a desk in horizontal direction then these represent collinear points. Students 1, 2 and 3 are collinear points.

Similarly, , students 1, 4 and 5 in the column are collinear points.

Please see the attached image to understand this.

-y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?
Dimas [21]

Answer:

Part 1) x=2.375

Part 2) y=3.3

Part 3) k=6.7

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

Part 1) y varies inversely with x. If y = 8 and k (the constant of variation) = 19, what is x?

we know that

y*x=k

substitute the given values and solve for x

8*x=19

x=19/8

x=2.375

Part 2) y varies inversely with x, and k (the constant of variation) = 23. What is the value of y when x = 7?

we know that

y*x=k

substitute the given values and solve for y

y*7=23

y=23/7

y=3.3

Part 3) y varies inversely with x. When y = 6.7, x = 1. What is the value of k, the constant of inverse variation?

we know that

y*x=k

substitute the given values and solve for k

6.7*1=k

k=6.7

HELP!!!In the expression 100 a/b, if a is greater than b, which statements are true? b ≠ 0. Select all that apply.
MAXImum [283]

Answer:

\large\boxed{\text{The expression is equal to}\ \sqrt[b]{100^a}}\\\boxed{\text{The expression is greater than 100}}

Step-by-step explanation:

a^\frac{m}{n}=\sqrt[n]{a^m}\\\\\text{True statement:}\\\\100^\frac{a}{b}=\sqrt[b]{100^a}\\\\a>b\to\dfrac{a}{b}>1\to\dfrac{a}{b}=1\dfrac{a-b}{b}\\\\100^\frac{a}{b}=100^{1\frac{a-b}{b}}=100^{1+\frac{a-b}{b}}=100^1\cdot100^\frac{a-b}{b}=100\sqrt[b]{100^{a-b}}\\\\a>b\to a-b>0\to100^{a-b}>1\\\\\text{Therefore}\ 100\sqrt[b]{100^{a-b}}>100
