Q. Solve the system of equations.y=41x+71y=x2+41x−50Write 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 they are both equal to y. This gives us the equation 41x+71=x2+41x−50.
Simplify the equation: Simplify the equation by subtracting 41x from both sides and subtracting 71 from both sides to get 0=x2−50−71.
Combine like terms: Combine like terms to get the simplified equation 0=x2−121.
Solve for x: Solve for x by finding the square roots of 121. Since the equation is x2=121, we take the square root of both sides to get x=±11.
Substitute x=11 into first equation: Now that we have the two possible values for x, we can substitute them back into the first equation y=41x+71 to find the corresponding y values. First, let's substitute x=11 into the equation.
Calculate y for x=11: Substituting x=11 into y=41x+71 gives us y=41(11)+71.
Substitute x=−11 into first equation: Calculate the value of y when x=11. This gives us y=451+71.
Calculate y for x=−11: Add 451 and 71 to get y=522.
Find two sets of solutions: Now let's substitute x=−11 into the equation y=41x+71 to find the corresponding y value for the second solution.
