Answer:

x=-3/7 and y=_23/7

Step-by-step explanation:

y=-4x-5 and y=3x-2

using comparison method

-4x-5=3x-2

-4x-3x=-2+5

-7x=3

x=3/-7

substituting the value of x

y=3x-2

=3×(-3/7)-2

=-9/7-2

=-9-14/7

=-23/7

Answer:

The answer is 69.5

Step-by-step explanation:

First u wanna find the area of the rectangle and since it already gives you the the height and width you want to multiply them together 13×4= 52

meanwhile triangle is 5ft tall and the base is 7ft

using the formula to solve for area of a triangle you would multiply height and base and divide by 2

you should end up with 17.5 then u add that to 52 and get 69.5 ♡ Hope this helps.

Answer:

x+2y = 5

2x+y=4

->

x+3y = 5

6x-y = 11

->

2x+y=10

x-3y=-2

Step-by-step explanation:

solutions of x and y for each system of equation can be solved by graphing

graph the two equations, and the intercepts of the two equations would be the x and y-values, aka the answers

if there are no intercepts, the equations have no solution
