Answer: 22

Step-by-step explanation:

$x + y= 39\\x-y=5\\$

multply the buttom eqn with -1

$x + y=39\\-x+y=-5$

solve for y

$2y=34\\y= 34/2\\y= 17$

substitute y into one of the eqn

$x+y=39\\x+17=39$

subtract 17 from both side

$x= 39-17\\x=22$

Solve the nonlinear inequality. express the solution using interval notation. (x − 2)(x + 8) < 0 webassign

stepladder [879]

First you find the zeros/x-intercepts using the factors already given in the inequality.

$x = 2$
$x = - 8$

Therefore we make our solution using the interval notation.

$- 8 \leqslant x \leqslant 2$
