Answer:

$318.17, out of state college is $161.12 cheaper per month

Step-by-step explanation:

72*24 = 1728 + 410*4 = 1728 + 1640 = 3368 + 450 = 18/12 = $318.17

8700+650*9 = 8700 + 5850 = 14550/9 = 1616.66

8500+400*9 = 8500 + 3600 = 12100 + 1000 = 13100/9 = 1455.56

1616.67 - 1455.56= $161.11 (use $161.12)

Solve the inequality 8(x + 1) > 7(x + 2).

elixir [45]

8X + 8 > 7x + 14

subtract 7x and 8 from both sides

x > 6

Through: (-5, 5), perp. to y = 5/9x - 4

zysi [14]

Answer:

$y=-\frac{9}{5}x-4$

Step-by-step explanation:

The complete question is:

Find the equation of the line that passes through: (-5, 5), and is perpendicular to the line y = 5/9x - 4

step 1

Find the slope of the line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)

The equation of the given line is

$y=\frac{5}{9}x-4$

The slope of the given line is

$m_1=\frac{5}{9}$

The opposite reciprocal is equal to

$m_2=-\frac{9}{5}$ ----> slope of the perpendicular line

step 2

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=-\frac{9}{5}$

$point\ (-5,5)$

substitute

$y-5=-\frac{9}{5}(x+5)$

step 3

Convert to slope intercept form

Isolate the variable y

$y-5=-\frac{9}{5}(x+5)\\\\y-5=-\frac{9}{5}x-9\\\\y=-\frac{9}{5}x-9+5\\\\y=-\frac{9}{5}x-4$
