Answer:

f(x) = 6x² -25x -9

Step-by-step explanation:

6x² - 25x -9 = (2x - 9) (3x + 1)

x = (2/9) or (- 1/3)

Select the expressions that are equivalent to 8 2/3

user100 [1]

To change a mixed fraction, you'd multiply the number upfront, times the denominator, and then add that product to the numerator
that IS the new numerator, and you keep the denominator
thus $\bf 8\frac{2}{3}\iff \cfrac{8\cdot 3+2}{3}$

inysia [295]

Answer:

$y = x + \$622.7\ billion$

Step-by-step explanation:

To start with;

Represent the budget of education by x

Represent the budget of defense by y

From the question, we understand that:

y exceeds x by $622.7 billion

Mathematically. this can be represented as:

$y = x + \$622.7\ billion$

Hence, the defense budget is x + $622.7 billion

Which is closest to the volume of a cylinder with a height of 11 inches and

Veseljchak [2.6K]

Answer:

The closest to the volume of cylinder is 63 in.³.

Step-by-step explanation:

Given:

Cylinder with a height of 11 inches and a circumference of 8 1/2 inches.

Now, to find the volume.

As circumference is given we get the radius by putting formula:

Circumference = 8 1/2 inches = 17/2 inches.

Let the radius be $r.$

$Circumference=2\pi r$

Taking the value of π = 3.14.

$\frac{17}{2}=2\times 3.14\times r$

$8.5=6.28\times r$

Dividing both sides by 6.28 we get:

$1.35=r$

So, radius = 1.35 inches.

Height = 11 inches.

Now, putting the formula to get the volume:

$Volume=\pi r^2h$

$Volume=3.14\times 1.35^2\times 11$

$Volume=3.14\times 1.8225\times 11$

$Volume=3.14\times 20.0475$

$Volume=62.949\ inches^3$

Hence, the volume of cylinder = 63 inches³ (approximately).

Therefore, the closest to the volume of cylinder is 63 in.³.
