Calculate the value of y at the given value of x and sketch a graph.
Answer to Problem 4CE
The solution is,
Explanation of Solution
Given: The algebraic equations are given,
Calculation:
Let’s take the first equation,
Put the value of x,
Then simplify the equation and calculate the value of y.
If we consider second equation
program:
clc clear close all symsxy a=2*x-7*y-9; b=x+y-0; xx=1:5; fori=1:5 s=subs(a,x,i); sol(i)=solve(s); s1=subs(b,x,i); sol1(i)=solve(s1); end plot(xx,sol,'linewidth',1.2) hold on plot(xx,sol1,'linewidth',1.2) set(gca,'linewidth',1.2,'fontsize',12) xlabel('x') ylabel('y') axis square
Query:
- First, we have defined both the algebraic equations.
- Then define the value of x.
- Then put the value of x into both the equations and calculate the value of y.
- Sketch a graph for y at different value of x.
