Hello from MrBillDoesMath!

Answer:

4( x + 1.5)^2 + 0

Discussion:

4x^2 + 12x + 9 = => factor "4" from first 2 terms

4 (x^2 + 3x) + 9 = => complete the square, add\subtract (1.5)^2

4(x^2 + 3x + (1.5)^2) - 4 (1.5)^2 + 9 =

4 ( x + 1.5)^2 + ( 9 - 4(1.5)^2) = => as (1.5)^2 = 2.25

4 ( x + 1.5)^2 + ( 9 - 4(2.25)) = => as 4 ( 2.25) = 9

4 ( x+ 1.5)^2 + 0

Thank you,

MrB

Gavin and Jack are practicing shots against their goalie. On their last 15 attempts, Gavin made 6 and Jack made 7. Based on this

statuscvo [17]

Answer:

$\dfrac{14}{75}$

Step-by-step explanation:

Gavin made 6 out of 15 shots, so the probability that Gavin's next shot will be successful is

$\dfrac{6}{15}=\dfrac{2}{5}$

Jack made 7 out of 15 shots, so the probability that Jack's next shot will be successful is

$\dfrac{7}{15}$

The probability that they both make their next shot successfully is

$\dfrac{2}{5}\cdot \dfrac{7}{15}=\dfrac{14}{75}$

Skye's two new aquariums each hold exactly 200 gallons of water. One aquarium will hold small fish and the other will hold large

Natasha_Volkova [10]

Answer=140 fish

200 gallons of water in the first aquarium.

200 gallons of water in the second aquarium.

The first will be for the small fishes.

5 small fish x fish
_____________=__________
10 gallons 200 gallons

cross multiply
10x=1000
divide both sides by 10
x=100 small fish

The first aquarium has 100 small fish.

The second aquarium holds large fish.

8 large fish x fish
____________=___________
40 gallons 200 gallons

cross multiply
40x=1600
divide both sides by 40
x=40 large fish

The second aquarium has 40 large fish.

100small fish+40 large fish=140 total fish

Suppose that y varies directly with x. Given x=4 when y=20.<br> Find y when x = 3

scoray [572]

Answer:

y = 15

Step-by-step explanation:

Given: y varies directly with x, x=4 when y=20

To find: y when x = 3

Solution:

As y varies directly as x, it means that as x increases, y also increases by the same factor.

As y varies directly with x,

$y=kx$

Here, k is a constant

As x = 4 when y = 20,

$20=4k\\k=\frac{20}{4}=5\\\Rightarrow y=5x$

Put x = 3

$y= 5(3) = 15$
