Q. Solve the system of equations.y=33x+11y=x2+33x−25Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y: Substitute y from the first equation into the second equation: y=x2+33x−25 becomes 33x+11=x2+33x−25.
Subtract and simplify: Subtract 33x from both sides to get 11=x2−25.
Add and solve for x: Add 25 to both sides to solve for x: 11+25=x2, which simplifies to 36=x2.
Take square root: Take the square root of both sides to find x: x=±36.
Calculate x values: Since 36 is 6, we have x=±6.
Calculate y for x=6: Plug x=6 into the first equation to find y: y=33(6)+11.
Calculate y for x=−6: Calculate y for x=6: y=198+11, which simplifies to y=209.
Find solution points: Now plug x=−6 into the first equation to find y: y=33(−6)+11.
Find solution points: Now plug x=−6 into the first equation to find y: y=33(−6)+11.Calculate y for x=−6: y=−198+11, which simplifies to y=−187.
Find solution points: Now plug x=−6 into the first equation to find y: y=33(−6)+11.Calculate y for x=−6: y=−198+11, which simplifies to y=−187.The solution to the system of equations is the points where the two graphs intersect, which are (6,209) and (−6,−187).
