Solve the system of equations by graphing. Check the solution. y=-2x-3. y=2x+5. Graph each equation on the same coordinate plane. At what point do the graphs of the lines appear to intersect?

Step-by-step explanation:

Substitute into one of the equations

Rearrange variables to the left side of the equation

Combine like terms

Calculate the sum or difference

Divide both sides of the equation by the coefficient of variable

Cross out the common factor

Substitute into one of the equations

Calculate

The solution of the system is

I hope this helps you! Don't forget to check the picture I uploaded as well

Step-by-step explanation:

Use the Elimination method sinse both coefficients in the system are OPPOCITES:

2y = 2; 1 = y [Plug this y-coordinate back into the system to get the x-coordinate of −2 (−2 = x)].

i dont know sorry

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
