-7 1/8 - -9 1/2

Rewrite 1/2 as 4/8:

-7 1/8 - -9 4/8

subtracting a negative becomes addition:

-7 1/8 + 9 4/8

= 2 3/8

The graph shows the amount of water that remains in a barrel after it begins to leak. The variable x represents the number of da

vivado [14]

A = ( 15 , 15 )

B = ( 6 , 33 )

$slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\$

$slope = \frac{33 - 15}{ 6 - 15} \\$

$slope = \frac{18}{ - 9} \\$

$slope = - 2$

Thanks for watching buddy good luck.

A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm,

Svetradugi [14.3K]

Answer:

The quadratic equation that best models the volume of the box (in terms of W) is:

$70W-5W^2$

Step-by-step explanation:

The perimeter of the rectangular base = 28cm

Perimeter of a rectangle = 2(L+W)

2(L+W)=28

L+W=14

L=14-W

Volume of the Box= LWH

Since L=14-W and Height Of the Box= 5cm

Volume of the Box= (14-W)W X 5

$=5(14W-W^2)\\ =70W-5W^2$

HELP PLEASE -9x + 3 > 39 OR - 5x + 6 < 16

Mama L [17]

9514 1404 393

Answer:

(-∞, -4) ∪ [-2, ∞)

Step-by-step explanation:

The solution to the first inequality is ...

-9x +3 > 39

-9x > 36 . . . . . subtract 3 from both sides

x < -4 . . . . . . . divide both sides by -9; reverse > to < because -9 is negative

The solution to the second inequality is ...

-5x +6 ≤ 16

-5x ≤ 10 . . . . . . . subtract 6 from both sides

x ≥ -2 . . . . . . divide both sides by -2; reverse ≤ to ≥ because -2 is negative

These solution sets are disjoint. The solution of the OR of these inequalities is the union of the solution sets. The graph is shown below. In interval notation, it is described by ...

(-∞, -4) ∪ [-2, ∞)

The -2 has a square bracket because it is included in the set. The curved bracket at -4 indicates it is not included.
