How can u order rational numbers from least to greatest

Step-by-step explanation:

If your list of numbers includes fractions and/or irrational numbers (such as π), rewrite all of them as decimal fractions:

Decimal fractions are easier to arrange in ascending order.

Ex:  3.2, π, 4

becomes 3.2, 3.14159, 4

and we see that 3.14159 is the smallest number, 3.2 is the middle number and 4 is the greatest.

Working with rational numbers?  As above, rewriting any fractions as decimal fractions will greatly ease the task of arranging your numbers in ascending order.

e. g., 25/2, 12, 15, 2

should be rewritten s 12.5, 12, 15, 2,  

which, arranged in ascending order, comes out to 2, 12, 12.5, 15.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
