Q. Solve the system of equations.y=21x−10y=x2+35x−25Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Substitute y into second equation: Substitute y from the first equation into the second equation. Since y=21x−10 and y=x2+35x−25, we can set them equal to each other: 21x−10=x2+35x−25.
Rearrange and solve for x: Rearrange the equation to set it to zero and solve for x: x2+35x−25−(21x−10)=0. This simplifies to x2+14x−15=0.
Factor the quadratic equation: Factor the quadratic equation: (x+15)(x−1)=0. This gives us two possible solutions for x: x=−15 or x=1.
Solve for y with x=−15: Solve for y using the first equation y=21x−10 with x=−15: y=21(−15)−10=−315−10=−325.
Solve for y with x=1: Solve for y using the first equation y=21x−10 with x=1: y=21(1)−10=21−10=11.
Write solution as coordinate points: Write the solution as coordinate points. The coordinate points are (−15,−325) and (1,11).
