Step-by-step explanation:

$midpoint = ( \frac{2 - 8}{2} , \frac{ - 6 + 5}{2} )$

$= ( \frac{ - 6}{2} , \frac{ - 1}{2} )$

$= ( - 3, - 0.5)$

The perimeter of a rectangular field is 296 yards. if the length of the field is 79 yards, what is its width?

Len [333]

Perimeter of rectangle is 2L + 2W
perimeter is 296
length of field is 79

Solve
2L + 2W = 296
2(79) + 2W = 296
158 + 2W = 296
2W = 296 - 158 = 138
W = 138/2 = 69 yards

I need help with these ASAP thanks

Answer:

a. $y=\frac{2x}{x-5}$

b. $y=\frac{2-4x}{x-3}$

Step-by-step explanation:

change switch x and y and then solve for y.

a. $x=\frac{5y}{y-2}$

$x(y-2)=5y$

$xy-2x=5y$

$xy-5y=2x$

$y(x-5)=2x$

$y=\frac{2x}{x-5}$

same for b.

b. $x=\frac{3y+2}{y+4}$

$x(y+4)=3y+2$

$xy+4x=3y+2$

$xy-3y=2-4x$

$y(x-3)=2-4x$

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

3y=4x+15 and 9x+12y=12 are perpendicular,parallel or neither

xxTIMURxx [149]

These two linear equations are <em>perpendicular</em>, because 3y=4x+15 has a slope of $\frac{4}{3}$ and 9x+12y=12 has a slope of - $\frac{3}{4}$ , and since those two fractions have exact opposite slopes (flip the denominator and numerator and multiply by -1), they are perpendicular.
