Answer: y=-1x+5
Step-by-step explanation:
1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.
m = ∆y / ∆x
m = -1 / 1
m = -1
y= -1x + b
2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)
y = mx + b
4 = -1(1) + b
4 = -1 + b
5 = b
3. Plug in the values found into the formula.
y = -1x + 5

Answer:
x = 2 and y = 5
Step-by-step explanation:
Given equations are :
y-x = 3 ......(1)
xy = 10 or
x = (10/y) ....(2)
Put the value of x in equation (1).
![y-\dfrac{10}{y}= 3\\\\y^2-10=3y\\\\y^2-3y-10=0\\\\y=0\ and\ y=5](https://tex.z-dn.net/?f=y-%5Cdfrac%7B10%7D%7By%7D%3D%203%5C%5C%5C%5Cy%5E2-10%3D3y%5C%5C%5C%5Cy%5E2-3y-10%3D0%5C%5C%5C%5Cy%3D0%5C%20and%5C%20y%3D5)
Put the value of y in equation (2).
![x=\dfrac{10}{5}\\\\x=2](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B10%7D%7B5%7D%5C%5C%5C%5Cx%3D2)
So, the value of x is equal to 2 and that of y is equal to 5.

Hello there! I can help you! So what we are looking for is the value of x. To find the value of x, we can write and solve an equation. Set it up like this:
4x + 28 = 180
This is because the sum of the angles for a triangle is 180°. We combine the like terms to get 4x and subtract 6 from 34 to get 28. First off, let's subtract 28 from both sides. 28 - 28 cancel out. 180 - 28 is 152. That simplifies into 4x = 152. Now, divide each side by 4 to isolate the x. 4x/4 cancels out. 152/4 is 38. There's a possible value of x. Let's plug the value in and see if it works. 38 * 2 is 76. 76 - 6 is 70. 38 + 34 is 72. 70 + 72 is 142 and 142 + 38 is 180. 180 = 180. There. x = 38. Here are the answers for the angle measurements:
(x + 34) = 72°
(2x - 6) = 70°
x° = 38°
