3x-7y=13
what is y?
need awnser

y= -13-3x÷7

Step-by-step explanation:

1st Subtract 3x from both sides: 3x-7y-3x=13-3x

2nd Simplify: -7y=13-3x

3rd Divide both sides by -7: -7y÷-7=13÷-7-3x÷-7

4th Simplify: -13-3x÷7

Hope this helps you out :)

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
