Mr. Zelman gave 400 books to his nephew

Solution:

Given that, Mr. Zelman wants to give 50% of his comic book collection to his nephew Alex

Mr. Zelman has 800 comic books

Number of books with Zelman = 800

Mr. Zelman wants to give 50% of books to Alex

Number of books given to nephew = 50 % of books of Zelman

Therefore, we have to find 50 % of 800

$\rightarrow 50 \% \text{ of } 800$

$\rightarrow 50 \% \times 800\\\\\rightarrow \frac{50}{100} \times 800 = 400$

Thus he gave 400 books to his nephew

What is the distance between the points (-4, 2) and (1, -3) on the coordinate plane?

ruslelena [56]

Answer:

A. 7.07 units

Step-by-step explanation:

Use the distance formula for coordinates:

$d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2 }$

Fill in the coordinates accordingly:

$d=\sqrt{(1-(-4))^2+(-3-2)^2}$

which simplifies down to

$d=\sqrt{25+25}$

which is of course

$d=\sqrt{50}$

Plug that into your calculator and you'll get the answer

expeople1 [14]

Answer:

$Y=(\frac{4}{7}) x+2$

Step-by-step explanation:

$Y=mx+b$

$M=\frac{x2-x1}{y2-y1}$

$M=\frac{0-(-4)}{-10-3}$

$M=\frac{-4}{-7}$

$Y=(\frac{4}{7}) x+2$
