6 0

Answer:

Step-by-step explanation:

u=\frac{15 \pm \sqrt{(-15)^2 -4\times 4 \times 18} }{2 \times 4}

u=\frac{15 \pm \sqrt{225-288} }{8} \\u=\frac{15 \pm \sqrt{-63} }{8} \\u=\frac{15 \pm \sqrt{63i^2 } }{8} \\u=\frac{15 \pm 3 \sqrt{7} i }{8}

Kia wants to order a large pizza from Frank's Pizza. Each large cheese pizza costs  $8.75 and each additional topping costs $0.5
Afina-wow [57]
<h2>Hello!</h2>

The answer is: A. 8.75 + 0.50 x ≤ 15.00

<h2>Why?</h2>

By isolating the variable (x), we have:

8.75 + 0.50x \leq15.00 \\0.50x\leq 15-8.75\\0.50x\leq 6.25\\x\leq \frac{6.25}{0.50}\\x\leq 12.5

So, with the result of x ≤ 12.5 , we can know that the most amount of additional toppings Kia got, is 12 toppings.

The inequality is telling us that Kia will spend 15$ or less if she orders 12 toppings or less.

Have a nice day!

The equation D=13/v shows that the density of a particular substance equals a mass of 13 grams divided by the volume of the subs
lions [1.4K]
For this case we have the following equation:
 D =  \frac{13}{v}
 Where,
 D: t<span>he density of a particular substance 
 v: </span><span> the volume of the substance
 </span>When replacing v = 0 in the given equation we have:
 D = \frac{13}{0}
 D =  \infty
 This means that as the function acquires values very close to zero, the density acquires a very large value.
 Answer:
 
as the volume approaches 0:
<span> The density approaches infinity.

Round 9.62 to the nearest whole number
mel-nik [20]

Answer:

10

Step-by-step explanation:

Anything greater than 9.49 would be rounded to 10, if it were 9.49, it would be rounded to 9. But only look at the numbers after the decimal.

i.e. ;

7.23 = 7

3.33 = 3

8.89 = 9

14.56 = 15

26.91 = 27
