Q. Solve the system of equations.y=17x+37y=x2+33x+20Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y Equation: Substitute y from the first equation into the second equation. Since y=17x+37, we can replace y in the second equation with 17x+37. This gives us 17x+37=x2+33x+20.
Rearrange and Solve: Rearrange the equation to set it to zero and solve for x. This means we subtract 17x+37 from both sides to get 0=x2+33x+20−17x−37.
Simplify Equation: Simplify the equation by combining like terms. This gives us 0=x2+16x−17.
Factor Quadratic Equation: Factor the quadratic equationx2+16x−17. We are looking for two numbers that multiply to −17 and add up to 16. These numbers are 17 and −1. So we can write the equation as (x+17)(x−1)=0.
Solve for x: Solve for x by setting each factor equal to zero. This gives us two solutions: x+17=0 or x−1=0. Therefore, x=−17 or x=1.
Substitute x=−17: Substitute x=−17 into the first equation y=17x+37 to find the corresponding value of y. This gives us y=17(−17)+37.
Calculate y for x=−17: Calculate the value of y when x=−17. This gives us y=−289+37, which simplifies to y=−252.
Substitute x=1: Substitute x=1 into the first equation y=17x+37 to find the corresponding value of y. This gives us y=17(1)+37.
Calculate y for x=1: Calculate the value of y when x=1. This gives us y=17+37, which simplifies to y=54.
