Find its x-coordinate.

Ilya [14]

Answer:

2.5

Step-by-step explanation:

The formula to find the midpoint of a line segment: $(\frac{1}{2}x_{1} + \frac{1}{2}x_{2}, \frac{1}{2}y_{1} + \frac{1}{2}y_{2})$

<u><em>Where:</em></u>

$x_{1} = -5\\x_{2} = 10\\y_{1} = 9\\y_{2} = 8$

1) Substitute the values into the midpoint formula.

$(\frac{1}{2}*-5 + \frac{1}{2}*10, \frac{1}{2}*9 + \frac{1}{2}*8)$

2) Solve it.

= $(-2.5 + 5, 4.5 + 4)$

= (2.5, 8.5)

You are using the 7 to see what the 8 will change to. Because the 7 is over 5 it will round up the 8 and so the answer would be 590

write an equation of a line that is perpendicular to the given line and that passes through the given point (4,-6); m=3/5

tresset_1 [31]

Answer:

$y=-\frac{5}{3} x-\frac{42}{5}$

Step-by-step explanation:

Given the slope and another point, simply plug them into the point-slope formula to find your y-intercept.

$y-y1=m(x-x1)\\y-(-6)=\frac{3}{5} (x-4)\\y+6=\frac{3}{5} x-\frac{12}{5} \\y=\frac{3}{5} x-\frac{42}{5}$

Now that we've found your y-intercept, we have the original equation. To find the perpendicular equation, you need the opposite reciprocal of your slope.

To find the 'opposite,' change your slope's sign. Since your slope is positive $\frac{3}{5}$ , the opposite is $-\frac{3}{5}$ .

To find the 'reciprocal,' flip your fraction. This will make your slope $-\frac{5}{3}$ .

Your final equation is:

$y=-\frac{5}{3} x-\frac{42}{5}$
