What is the ordered pair for y + 3x = -1 and 2y - 5x =31

Multiply the first equation in    y + 3x = -1 and 2y - 5x =31     by -2, to obtain:

-2(y + 3x = -1)     =>  -2y - 6x = +4
                                   2y        =    5x + 31   (this is the 2nd equation)
                                 
                                        -6x  = 5x + 35, or -11x = 35, or x = -35/11

Subst.  -35/11 for x in either of the given equations, to find the value of y.

Then write y our solution in the form (-35/11,   ?    ).

As always, you should check your answer.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12

Maybe fx = lxl because of the way the x is positioned is that what he
