2x + y = 4
y = 3x - 1
Is (1, 2) a solution to both equations?
yes or no?

yes

Step-by-step explanation:

2x+y=4 x=1 and y=2 2(1)+2=4

y=3x-1 3(1)-1=2

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.
