Answer:

Step-by-step explanation:

We can get two equations from the inequality:

$3x+2>9\\3x+2>-9$

We just need to simplify both equations to get our answers:

$3x+2>9\\3x>7\\x>\frac{7}{3}$

$3x+2>-9\\3x>-11\\x>\frac{-11}{3}$

The two answers we get are:

$x\frac{7}{3}$

Which is also B.

A department store sold 62 shirts one day. All short-sleeved shirts cost $11.00 each and all long-sleeved shirts cost $17.00 eac

slava [35]

Answer:

a. Short-Sleeve = 35

b. Long-Sleeve = 27

Step-by-step explanation:

Given data:

Total shirts sold = 62

short sleeved cost = 11 each

Long sleeved cost = 17 each

Total receipts = 844

Let the count of short sleeved be X and Let the count of long sleeved be Y

X + Y = 62 (equation 1) from the total shirts sold

11X + 17Y = 844 (equation 2) from the total receipts

From equation 1 X = 62 - Y (Equation 3)

Substituting equation 3 into equation 2

11(62 - Y) +17Y = 844

682 -11Y + 17Y = 844

-11Y + 17Y = 844-682

6Y = 162

Therefore Y = 27

Substituting Y into equation 3

X = 62 - Y

X = 62 - 27

X = 35

The slope of the line below is -5 which of the following is the point-slope form of the line (2,-8)

insens350 [35]

The point slope form has the following syntax.

$y - y_1 = m(x - x_1)$
m = slope = -5
$y - y_1 = -5(x - x_1)$
(x,y) = (2,-8)
$x_1 = 2$
$y_1 = -8$
$y - y_1 = -5(x - x_1)$
$y - (-8) = -5(x - 2)$
$y + 8 = -5(x - 2)$ <------Answer
