Methods for solving systems
We will be looking at two methods for solving systems in this section.
Method of substitution
The first method is known as the method of substitution. In this method we will solve out one of the equations for one of the variables & substitute it into the other equation. It will yield one equation along with one variable that we can solve out. Once it is solved we substitute this value back in one of the equations to determine the value of the remaining variable.
In words this method is not always very apparent. Let's work on examples to see how this method works.
In a certain class, one half of the male students and two thirds of the female students speak Freanch. If there are three fourths as many girls as boys in the class. What fractio
6[5b+9]=2b+9.
I am supposed to put y= -2x-16x-32 in vertex form and identify the vertex , axis of symmetry, and direction of opening.
need help with solve a= 3p(4-2r) for p
I don''t understand anything!
change this radical to a algebraic expression with fractional exponnents 5 squar root x^3
7w+2=3w+94
Multiply 2(b + 5) Thanks
how would i solve one of these functions. like how would i find the domain and range? and may i get an example.
in her last gymnastics competition Keri scored a 5.6 on the floor exercise, 5.85 on the vault and 5.90 on the balance beam. what was keri''s total?
