Solve the following system of equations graphically.
y = 2x - 3
x + y = 3
what is the solution set?
{(2, 1)}
{(1, 2)}
{(-1, -2)}
{(-2, -1)}

(2,1)

Step-by-step explanation:

Let us graph our first equation

y = 2x - 3

Bring y to the right hands side and 3 to the left hand side of = we get

2x-y=3

Diving each term of the equation by 3 we get

Hence we have converted our equation into intercept form, in x intercept is and y intercept is -3.

Now we mark the two points are as and (0,-3)

Shown as red line in attachment.

x + y = 3

Dividing both sides by 3

Hence our x and y intercepts are 3. Thus we plot coordinates (3,0) and (0,3) and join them together to graph our line.In attachment it is shown in as blue line.

Please refer to the image in the attachment. The two lines intersect at (2,1)

This is our solution.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

the first option is the answer.
