I dont know the answer but i just need point for a question sorry
Answer:
(x, y) = (2, 5)
Step-by-step explanation:
I find it easier to solve equations like this by solving for x' = 1/x and y' = 1/y. The equations then become ...
3x' -y' = 13/10
x' +2y' = 9/10
Adding twice the first equation to the second, we get ...
2(3x' -y') +(x' +2y') = 2(13/10) +(9/10)
7x' = 35/10 . . . . . . simplify
x' = 5/10 = 1/2 . . . . divide by 7
Using the first equation to find y', we have ...
y' = 3x' -13/10 = 3(5/10) -13/10 = 2/10 = 1/5
So, the solution is ...
x = 1/x' = 1/(1/2) = 2
y = 1/y' = 1/(1/5) = 5
(x, y) = (2, 5)

The attached graph shows the original equations. There are two points of intersection of the curves, one at (0, 0). Of course, both equations are undefined at that point, so each graph will have a "hole" there.
Answer:
<u>f(x) = x² - 4x + 2 or f(x) = (x - 2)²</u>
Step-b<u>y</u>-step explanation:
- The parabola touches the x-axis at only one point
- If we use y = a(x − h)² + k, we can see from the graph that h = 2 and k = 0
- This gives us y = a(x − 2)²
What is the value of "a"?
- We also see that the y-intercept is (0, 4)
- We can plug it into the equation
- 4 = a(0 - 2)²
- 4a = 4
- a = 1
<u>So, our quadratic equation will be</u> :
- y = 1(x - 2)²
- <u>y = x² - 4x + 2 or y = (x - 2)²</u>
