Solve the problem using a system of equations in two variables. Find two positive numbers whose squares have a sum of 25 and a difference of 7. h The two numbers are 1 (Use a comma to separate answers.)
you must set up 2 equations, you must set up the
matrices.
Solve the following word problems. Remember: define your variables, write a system of equations to represent the situation, and use elimination or substitution to solve. 1. The sum of twice a number and 4 times another number is 4. The first number decreased by the second number is 5. Find the numbers.
Set up an equation and solve the problem. Suppose that the sum of two numbers is 20, and the sum of their squares is 250. Find the numbers.

(iv) Describe S as looking like either...
PLEASE TYPE create a graph Post a list of numbers that others will use to find statistical parameters (mean, median and standard deviation). Keep your list of numbers less than 10 values. You will then solve a post from another student and give your solutions for the mean, median and standard deviation. Please include all details in your solution and show your work. You can attached an EXCEL file, if desired or show your EXCEL equations used to find your...
use 5 digits pls thx
