Q. Solve the system of equations.y=7x+100y=x2+7x−44Write 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: y=x2+7x−44 becomes 7x+100=x2+7x−44.
Solve for x: Subtract 7x from both sides to get 100=x2−44.
Find x: Add 44 to both sides to get x2=144.
Calculate y for x=12: Take the square root of both sides to find x. This gives us x=12 and x=−12, since both 122 and (−12)2 equal 144.
Calculate y for x=−12: Plug x=12 into the first equation y=7x+100 to find the corresponding y value. This gives us y=7(12)+100.
Calculate y for x=−12: Plug x=12 into the first equation y=7x+100 to find the corresponding y value. This gives us y=7(12)+100.Calculate y for x=12. y=84+100, which is y=184.
Calculate y for x=−12: Plug x=12 into the first equation y=7x+100 to find the corresponding y value. This gives us y=7(12)+100.Calculate y for x=12. y=84+100, which is y=184.Now plug x=−12 into the first equation y=7x+100 to find the corresponding y value. This gives us x=−123.
Calculate y for x=−12: Plug x=12 into the first equation y=7x+100 to find the corresponding y value. This gives us y=7(12)+100.Calculate y for x=12. y=84+100, which is y=184.Now plug x=−12 into the first equation y=7x+100 to find the corresponding y value. This gives us x=−123.Calculate y for x=−12. x=−126, which is x=−127.
