Answer:
minus 4
Step-by-step explanation:
y=3x-7
y=3-7
y=-4
(1,-4)
Y^2 + z^2=x^2
In a right triangle the sum of the sides^2 are equal to the hypotenuse^2
Hello! We already have the equation set up, which is 9x = x + 4. Let's solve for x. Subtract x from both sides to get each side by itself x - x cancels out. 9x - x is 8x. That leaves 8x = 4. Now, divide each side by 8 to isolate the x. 8x/8 cancels out. 4/8 is 4/8 or 1/2 in cimplest form. Let's plug this value in and see if it works. 9 * 1/2 is 4 1/2. 1/2 + 4 is 4 1/2. 4 1/2 = 4 1/2. There. x = 1/2.
Hey there!
Explanation:
First, you had to do is add by 13 from both sides of an equation.

Then, simplify or add by the numbers.


Next, you can also divide by 3 from both sides of an equation.

And finally, simplify and divide by the numbers,

*The answer must have a positive sign.*

Hope this helps!
Answer:
1) If both x and y are positive then this point is at quadrant I (it is upper-right quadrant). 2) If x is negative but y is positive then point is at quadrant II (this one is upper-left quadrant). 3) If x and y are negative then point is at quadrant III (lower-left).
