Help me please I am confused with the question about the 3 digit number ?

Mathematics
1 answer:
vazorg [7]2 years ago

Answer:

900

Step-by-step explanation:

3-digit natural numbers are whole numbers that range from 100 to 999 (3-digit because there are three numbers)

- 999 whole numbers from 1 to 999 (counting from 1, 2, 3, 4...897, 898, 899)

- 1 to 99 are 2-digit numbers, so you do not count them

  • 999 - 99 = 900

there are 900 3-digit natural numbers!  

comment or message me if you are still confused!

Can someone please answer this???? ASAP

Answer:

A. y=-\dfrac{8}{7}x-\dfrac{18}{7}

Step-by-step explanation:

Let y=mx+b be the equation of the perpendicular line.

Two perpendicular lines have slopes with product equal to -1. The slope of the given line is \frac{7}{8} Hence,

\dfrac{7}{8}\cdot m=-1\\ \\m=-\dfrac{8}{7}

is the slope of needed line.

This line passes through the point (-4,2), so its coordinates satisfy the equation:

2=-\dfrac{8}{7}\cdot (-4)+b\\ \\b=2-\dfrac{32}{7}=-\dfrac{18}{7}

Therefore, the equation of the line is

y=-\dfrac{8}{7}x-\dfrac{18}{7}
