Graph the equations to solve the system
y=-x
y=2x+3
click on the correct answer #1 solutions : all numbers on the line #2 no solutions {} #3 one solution: {-1,1} #4 one solution: {0,3}

This system has one solution (-1,1)

Step-by-step explanation:

The attached picture shows the solutions for the system

If we equalize the eq. obtain the following

-x=2x+3

From we obtain that x= -1

Using the first equation y=-x, we obtain that y=1

so (-1,1)

i have no answer for this maybe o 7 units

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
