Q. Solve the system of equations.y=−35x−8y=x2−21x+5Write the coordinates in exact form. Simplify all fractions and radicals.(______,______)(______,______)
Set Equations Equal: Set the two equations equal to each other since they both equal y.y=−35x−8y=x2−21x+5So, x2−21x+5=−35x−8.
Rearrange and Combine Terms: Rearrange the equation to set it to zero and combine like terms.x2−21x+5+35x+8=0x2+14x+13=0
Solve for x: Solve for x by setting each factor equal to zero.x+1=0 or x+13=0This gives us x=−1 or x=−13.
Substitute x Values: Substitute x=−1 into one of the original equations to find the corresponding y value.Using y=−35x−8, we get y=−35(−1)−8=35−8=27.
Write Coordinate Points: Substitute x=−13 into the same original equation to find the corresponding y value.Using y=−35x−8, we get y=−35(−13)−8=455−8=447.
Write Coordinate Points: Substitute x=−13 into the same original equation to find the corresponding y value.Using y=−35x−8, we get y=−35(−13)−8=455−8=447.Write the solution as coordinate points.The coordinate points are (−1,27) and (−13,447).
