Solve the following simultaneous equations by drawing graphs, (a) x +y=7 and y=x-3
b) x + y = 8 and x=y

a) x = 5 and y = 2

b) x = 4 and y = 4

Step-by-step explanation:

Here, we want to solve the simultaneous equations by graphing

We shall be using an external graphing tool for this

The point at which the lines intersect represent the solution to the equation

please check attachment for the plots

For the first equation, we have the solution as;

x = 5 and y = 2

For the second, we have;

x = 4 and y = 4

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

36
