Is (2, 5) a solution to this system of equations? 10x + y = 17 4x + 2y = 18 No, (2, 5) is not a solution.
Yes, (2, 5) is a solution.

here's the solution,

let's solve for the equations : -

=》

and

=》

now, by multiplying first equation by 2

we get ,

=》

=》

now, let's subtract second equation from the first equation ( just multiplied by 2)

=》

=》

=》

=》

then, plugging value of x as 1 in first equation,

=》

=》

=》

the system of linear equations have a unique solution which is (1 , 7) , so

No, (2 , 5) is not a solution

step-by-step explanation:

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
