Q:

will mark brainliest (simple algebra) Write an equation and graph the line given the point: (-4, -6) and slope: 5

Accepted Solution

A:
Answer:x   = 7Step-by-step explanation:given equation is : 14x-49 = x² adding -x² to both sides of equation,we get -x²+14x-49   = -x²+x² -x²+14x+49   = 0 take -1 as common -1(x²-14x-49)   = 0 now multiplying above equation to -1, we get x²-14x-49   = 0 now, above equation is in general equation. split the middle term of above equation so that the product of two terms should be 49 and sum be -14. x²-7x-7x-49   = 0 make two groups x(x-7)-7(x-7)   = 0 take (x-7) as common (x-7)(x-7)   = 0 now applying zero-product property to above equation,we get x-7   = 0 or x-7   = 0 as both are same ,hence x-7   = 0 adding 7 to both sides of above equation,we get x-7+7   = 0+7 x+0   = 7 x   = 7 which is the answer... BTW I did all of that just to be brainliest ;D
