Lets m is the number of miles 

23.95(3) + 0.32m = 250
71.85 + 0.32m = 250
0.32m = 250 - 71.85
0.32m = 178.15
m = 178.15  /  0.32
m = 556.71

answer: <span>Trevor can drive 556 whole miles on a $250 budget</span>

Y=mx +b plug that in , so the 23.95 would be the flat fee then you add 0.32 
       250 =23.95+0.32 subtract from both sides then divide the answer is  10 miles

X²+Y²=250 and XY=117<br> What are the values of X and Y?
yan [13]

Answer:

<h3>            x = -9,  y = -13 </h3><h3>    or    x = 13,   y = 9</h3><h3>    or    x = -13,  y = -9</h3><h3>    or     x = 9,   y = 13</h3>

Step-by-step explanation:

x^2+y^2=250\\\\x^2-2xy+y^2+2xy=250\\\\(x-y)^2=250-2xy\\\\(x-y)^2=250-2\cdot117\\\\ (x-y)^2=16\\\\x-y=4\qquad\qquad\vee\qquad \qquad  x-y=-4\\\\x=4+y \qquad\qquad \vee\qquad\qquad x=-4+y\\\\(y+4)y=117\qquad\vee\qquad\quad (y-4)y=117\\\\y^2+4y-117=0\qquad\vee\qquad y^2-4y-117=0\\\\y=\dfrac{-4\pm\sqrt{4^2-4(-117)}}{2\cdot1}\qquad\vee\qquad y=\dfrac{4\pm\sqrt{4^2-4(-117)}}{2\cdot1}\\\\y=\dfrac{-4\pm\sqrt{16+468}}{2}\qquad\ \ \vee\qquad y=\dfrac{4\pm\sqrt{16+468}}{2}

y_1=\dfrac{-4-22}{2}\ ,\quad y_2=\dfrac{-4+22}{2}\ ,\quad y_3=\dfrac{4-22}{2}\ ,\quad y_4=\dfrac{4+22}{2}\\\\y_1=-13\ ,\qquad y_2=9\ ,\qquad\quad\qquad\ y_3=-9\ ,\qquad y_4=13\\\\x_{1,2}=4+y_{1,2}\qquad\qquad\qquad\qquad\qquad x_{3,4}=-4+y_{3,4}\\\\x_1=-9\ ,\qquad x_2=13\ ,\qquad\quad\qquad x_3=-13\ ,\qquad x_4=9

A line with a slope of -2/5 that passes through the point (-10,8)
slamgirl [31]

Step-by-step explanation:

m =  -  \frac{2}{3}  \\ ( - 10 ,\: 8) = (x_1,y_1)

y-y_1=m(x-x_1)

Plug in the values into the equation

y - 8 =  -  \frac{2}{3} (x - ( - 10)) \\ y - 8 =  -  \frac{2}{3}( x + 10) \\

y - 8 =  -  \frac{2}{3} x  -  \frac{20}{ 3 }  \\ y =  -  \frac{2}{3} x -  \frac{20}{3}  + 8 \\

y =  -  \frac{2}{3} x +  \frac{4}{3}

To solve for x-intercept , Arrange the values in

ax + by + c = 0

=

-  \frac{2}{3} x - y +  \frac{4}{3}  = 0

To find x-intercept .let y = 0 in the above equation

-  \frac{2}{3} x - y +  \frac{4}{3}  = 0 \\  -  \frac{2}{3} x - 0 +  \frac{4}{3}  = 0 \\

-  \frac{2}{3} x +  \frac{4}{3}  = 0 \\  -  \frac{2}{3} x =  -  \frac{4}{3}

Solve for x ;

x = 2

To find y intercept , let x = 0

and solve for y .

I hope it helps <3
