-7x - 10y = 40
-7x + 7x - 10y = 40 + 7x
       <u>-10y</u> = <u>40 + 7x</u>
       -10       -10
      y = -4 - ⁷/₁₀x

NO, it's not you have to move the negative 7 to the other side wich makes it positive so you will be left with -10y=7x+40 so then you divide everything by -10
so then it will be y=7/-10x+40/-10
so the final answer will be y=7/-10-4

The University of Southern California is located about 2.5 miles west and about 2.8 miles south of downtown Los Angeles. Suppose

Jlenok [28]

If x represents distance measured east of downtown, and y represents distance measured north of downtown, the circle of radius 40 centered at (-2.5, -2.8) will have an equation of the form
(x - h)² + (y - k)² = r²
where the center is (h, k) and the radius is r. The locus of points 4 miles from USC will satisfy the equation
(x +2.5)² + (y + 2.8)² = 1600
