You are given the system of equations to solve by the elimination method, which is an INCORRECT step that will NOT produce a system with the same solution? 5x + 4y = 4
3x + 6y = 12

A) subtract 2 times the second equation from 3 times the first equation
B) add 3 times the first equation and −2 times the second equation
C) multiply the first equation by 3 2 and subtract the second equation
D) multiply 4y by 3 2 in the first equation and subtract the second equation

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
