PLLZZZ I NEED HELP DUE NOWW

14a. x=3, y=-1

14b. 12

14c. 40

Step-by-step explanation:

Opposite sides have to be equal, so you can write the following equations:

4 x + 2 y = x - 3 y + 4

2 x + 2 y = x - y

Simplify both:

3x + 5y = 4

x = - 3y

Plug the second into the first:

-9y + 5y = 4

-4y = 4

y = -1

so

x = -3*-1 = 3

The perimeter is a matter of filling in x and y in the formulas:

10 + 4 + 10 + 4 = 32

Now that we know the side lengths 4 and 10, the area is their multiplication

4*10 = 40

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
