Answer:

solution of the given system of equation is (4,7)

C is the correct option.

Step-by-step explanation:

The given system of equations is

$2x+3y=29...(i)\\\\x=4...(ii)$

Substituting the value of x from (ii) in equation (i)

$2\cdot4+3y=29\\\\8+3y=29\\\\3y=21\\\\y=7$

Therefore, the solution of the given system of equation is (4,7)

C is the correct option.

What are 2 points on the graph for 6x-5y=25

zepelin [54]

To find any two random point on the graph of 6x-5y=25, we can just plug in any two values for x and solve for y, and find the 2 points in the form of (x,y).

So lets plug in x=0.

$\sf 6x-5y=25$
$\sf 6(0)-5y=25$
$\sf -5y=25$
$\sf y=-5$
So one point is (0,-5)

And to find another point, we can plug in x=1

$\sf 6x-5y=25$
$\sf 6(1)-5y=25$
$\sf 6-5y=25$
$\sf -5y=25-6$
$\sf -5y=19$
$\sf y=19/-5$
$\sf y=-3.8$
So another point is (1,-3.8)

Which ordered pair is a solution of the equation

Mrrafil [7]

Answer:

Step-by-step explanation:

y - 3 = 5(x - 2)

y - 3 = 5x - 10 Add 3 to both sides

y = 5x - 7

Let x = 2

y = 5*2 - 7

y = 3

So (2,3) works

Let x = 3

y = 5*3 - 7

y = 15 -7

y = 8

The answer is A
