Solve each by elimination 1. 6x - 4y = 0       -12 + 8y = 0 2. 12x + 10y = 16       -6x - 5y = -8 3. 6x - 8y = -14         3x + 12y = 18 4. 4x - 5y = 4         -9x + 12y = 18 5. 3x - 5y = 1         4x - 2y = -8 6. 20x - 25y = 10       12x - 15y = 9

this doesn't make sense lol

step-by-step explanation:

idk

i hope i

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

no solution exists the way you wrote the equation.
