Answer:
I believe what your asking me to do is put the y value back into the equation and solve for x. If so x=6 or x=(5/9) SEE BELOW
Step-by-step explanation:
y=(2/3)x-1 , y=3
3=(2/3)x-1
4=(2/3)x
x=6
OR
y=2/(3x-1)
x=(5/9)

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg <em>a</em> = 7.5
Leg <em>b</em> = 10
Hypotenuse <em>c</em> = <em>c</em>
<em />
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute in variables [Pythagorean Theorem]: 7.5² + 10² = c²
- Rewrite: c² = 7.5² + 10²
- Evaluate exponents: c² = 56.25 + 100
- Add: c² = 156.25
- [Equality Property] Square root both sides: c = 12.5

Answer:
49/100
Reason:
49/100 is already in simplest form, there is no number that you can divide 49 and 100 by that results in a whole number for both of them.
Y=21n(x2+2)y=21n(x2+2)
21n(x2+2)(y-1)=0
n=0, x=i/2-i/2, y=1
