snow_lady [41]

Answer:

$6\frac{3}{4}\ ft$

Step-by-step explanation:

we know that

To find out how long is Ms.Smith’s bulletin board, multiply Mrs . Porcelli’s bulletin board by 3

$2\frac{1}{4}(3)$

but first convert mixed number to an improper fraction

$2\frac{1}{4}\ ft=2+\frac{1}{4}=\frac{9}{4}\ ft$

substitute

$\frac{9}{4}(3)=\frac{27}{4}\ ft$

convert to mixed number

$\frac{27}{4}\ ft=\frac{24}{4}+\frac{3}{4}=6\frac{3}{4}\ ft$

Graph x^3 - 3x^2 + 2 = 0.1 - x What are the solutions of the equation?

liq [111]

Answer:

$x=-0.6,x=1.52,x=2.08$

Step-by-step explanation:

Let $f(x)=x^3-3x^2+2$ .

and

$g(x)=0.1-x$

The graph of the two equations are shown in the attachment.

The points where the two graphs intersected are: $(-0.6,0.7),(1.52,-1.42),(2.08,-1.98)$

The x-coordinates of the intersection points are the solutions to $x^3-3x^2+2=0.1-x$ .

Therefore the solutions are: $x=-0.6,x=1.52,x=2.08$

sattari [20]

Answer:

Step-by-step explanation:

5(x - 3) = 2(x + 3) Distribute

5x - 15 = 2x + 6

+ 15 + 15 Switch sides to the liked terms

5x = 2x + 6 + 15

-2x -2x Switch sides to the liked terms

5x - 2x = 6 + 15
