x + 4 > 14 [ (x + 4) is greater than 14]

So the other side of the equation has to be more than 14, you can be at least 15. Since it doesn't have a line underneath, it can not be 14.

> greater than, < less than

≥ greater than or equal to, ≤ less than or equal to

A. "have at most 14 bottles" This is saying they have a maximum of 14, which is false because it can't be equal to 14

B. "must sell at least 14 cookbooks" This is saying they need a minimum of 14, which is false because it can't be equal to 14

C. "have fewer than 14 hats" This is saying they are below/under/less than 14, which is false because it can't be less than 14

D. "must swim more than 14 laps" This is saying they need to be above 14, which is true

What are the zeroes of f(x) = x2 − 6x + 8? (4 points) x = −4, 2 x = −4, −2 x = 4, 2 x = 4, −2

babymother [125]

Hey there! :)

Answer:

Third option. x = 2, and x = 4.

Step-by-step explanation:

Find the zeros of this quadratic equation by factoring:

f(x) = x² - 6x + 8

Becomes:

f(x) = (x - 4)(x - 2)

Set each factor equal to 0 to solve for the roots;

x - 4 = 0

x = 4

x - 2 = 0

x = 2

Therefore, the zeros of this equation are at x = 2, and x = 4.

To win at LOTTO in one state, one must correctly select 4 numbers from a collection of 50 numbers (1 through 50). The order i

Oksana_A [137]

Answer:

230,300 different selections.

Step-by-step explanation:

If the order does not matter, the number of possible different selections is determined as the combination of choosing four numbers out of 50:

$n=\frac{50!}{(50-4)!4!}\\\\n=\frac{50*49*48*47}{4*3*2*1} \\\\n=230,300\ combinations$

There are 230,300 possible different selections.

Sharon buys a new phone that is $144.60. It is on sale for 25% off, and she has to pay a 6.5% sales tax. How much does she pay f

-BARSIC- [3]

Answer:

$ $115.50$

Step-by-step explanation:

To find out what she paid with the discount and no tax, turn the percentage into a decimal. To do that, divide it by 100.

$25 / 100= .25$

Then, multiply that by the total.

$.25 * 144.6= 36.15$

Subtract that by the total.

$144.6 - 36.15=108.45$

Now, we need to find the sales tax. Again, we know to divide the percentage by 100 to get the decimal. In that case, 6.5% is now .065.

Multiply that by the discounted price.

$.65 * 108.45= 7.05$

Add that to the price.

$108.45 + 7.05 =115.50$

$ $115.5$ would be the total price.
