Many real world scenarios can be modeled using systems of equations. In fact, when we have two quantities that
are related and two ways in which those quantities are related, then we can often set up and solve a system.
Exercise #1: Jonathan has nine bills in his wallet that are all either five-dollar bills or ten-dollar bills.
(a) Fill out the following table to see the (b) If f represents the number of $5 bills and t dependence of the two
variables and how they represents the number of $10 bills, then what then determine how much money
Jonathan has. does the following expression calculate? Explain.
Number
of fives, f
0
Number
of tens, t
Amount of Money. S

b) If f represents the number of $5 bills and t represents the
number of $10 bills, then what does the following
expression calculate? Explain. 5f+ 10t

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

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
