Lauren solved the equation $|x-5| = 2$. meanwhile jane solved an equation of the form $x^2+ bx + c = 0$ that had the same two so
lutions for $x$ as lauren's equation. what is the ordered pair $(b, c)$?
1 answer:
You must first solve the equation with absolute value, which has two possible solutions that in this case are x = 7 and x = 3. The equation is solved by applying the definition of absolute value. Then, you must solve the second-degree polynomial by applying the resolver and matching both solutions to the absolute value solutions.The result will be (b, c) = (- 10,21). I attach the correct solution.

Answer:
y = x -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - x - 3 ← is in slope- intercept form
with slope m = -
Parallel lines have equal slopes , then
y = - x + c ← is the partial equation of line d
to find c substitute (- 2, - 2 ) into the partial equation
- 2 = + c ⇒ c = - 2 -
= -
y = - x -
← equation of line d
