Equating the y's:-
3x + c = x^2 - 5x + 7
x^2 - 8x +7 - c = 0
If y = 3x + c is a tangent then there will be duplicate solutions to this equation
That is the discriminant b^2 - 4ac = 0. So we have:-
(-8)^2 - 4 * 1 * (7 -c) = 0
64 -28 + 4c = 0
4c = - 36
so c = -9 answer

Answer:
alternate exterior angles
Step-by-step explanation:
When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.
Well, you first have to make the mixed fraction into an improper fraction. You then multiply the two fractions and ad the whole number into the total.
That's how i was taught back in the 4th grade... i'm not sure if it's correct but i hope it is-
