Answer:

Step-by-step explanation:

x = 2:

4(4 + 2 - 3) - 6 + 3 = 12 - 6 + 3 = 9

x = 3:

4(6 + 3 - 3) - 9 + 3 = 24 - 9 + 3 = 18

9(x - 1)

4(3x-3) - 3x + 3

Step-by-step explanation:

4(2x + x-3) - 3x + 3

Combine like terms

4(3x-3) - 3x + 3

Distribute

12x -12 -3x+3

Combine like terms

9x -9

Factor out 9

Answer:

42) 254.47 ft²

43) 56 pendants

Step-by-step explanation:

42)

The radius of a circle is equal to half of its diameter.

Diameter = 18 feet

Radius = Diameter ÷ 2 = 18 ÷ 2 = 9 feet

Area of a circle = π $r^{2}$

Substitute in known value of r

Area = π $9^{2}$

Substitute in pi

Area = 3.14 * $9^{2}$

Solve exponent

Area = 3.14159265359 * 81

Area = 254.4690049408

(Rounds to 254.47)

254.47 ft²

43)

$1\frac{1}{2} =$ 1.5 ounces per pendant

3 pieces of silver:

$1\frac{7}{8}$ pounds

14 ounces

$2\frac{1}{2}$ pounds

Convert to improper fractions (1 lb = 16 ounces)

$\frac{15}{8}$ pounds

$\frac{14}{16}$ pounds

$\frac{5}{2}$ pounds

Find a common denominator for the fractions

$\frac{30}{16}$ pounds

$\frac{14}{16}$ pounds

$\frac{40}{16}$ pounds

Add

$\frac{30}{16}$ + $\frac{14}{16}$ + $\frac{40}{16}$

$\frac{84}{16}$ pounds

Find how many pendants can be made out of this amount

$\frac{84}{16}$ pounds

Convert back to ounces (1 lb = 16 ounces)

84 ounces

Amount to make one pendant:

$1\frac{1}{2}$ ounces

Convert to decimal

1.5 ounces

Divide 84 by amount of silver per pendant

84 ÷ 1.5

The maximum number the pendants that the manufacturer can make is 56

Hope this helps :)

Answer:

14.6

Step-by-step explanation:

The computation of average price paid for the share is shown below:-

$Average = \frac{Total\ investment}{Total\ share}$

= $\frac{6,000}{410}$

= 14.6

For more clarification please find the attachment as attached using excel spreadsheet.

By dividing the total investment by the total number of shares we can get the average price paid for the share and the same is to be considered

Moreover, the total investment and the total shares are shown in the attachment. Kindly find it below:

How does the graph of g(x) = (x + 2)^3 − 7 compare to the parent function of f(x) = x^3

pickupchik [31]

Answer:

Step-by-step explanation:

The tricky part is always what is in the brackets with the x. It is highly anti intuitive.

(x + 2) moves the graph left, not right as you might think. So from this, only C and D can be considered as answers.

Since the 2 is with the x, that's how many units left you will go -- 2 units.

C is the only possible answer.

The - 7 tells you it will move 7 units down. The 7 with a minus acts the way you think it should. It goes down which is what normally happens on a graph. A mnus number outside the brackets means down.

There are 5 red roses, 3 yellow roses, and 8 white roses in a tray. If Stephanie picked 2 roses one after the other without repl

Wewaii [24]

So probility is (disired outcomes) divided by (total possible outcomes) so

1st one is white roses
8 white roses so 8 is disired
total=5+3+8=16
8/16=1/2
then without replacing them
red=5
total possible=16-1 since 1 picked
5/15=1/3
then multiply the probatilities

1/2 times 1/3=1/6
it is a 1 in 6 probability
