Evaluate the expression: -|-14| HELPPPPPPPPPP!!!!!! (its worth all my points!!) ( ik its sad

Serhud [2]

Answer: -14

Step-by-step explanation: Here we're asked to simplify -|-14| so we

start by simplifying the absolute value of -14.

Remember that the absolute value of

any positive or negative integer is positive.

So the absolute value of -14 is 14.

So we write (14) in parenthses like I have just done.

Next, we bring down the negative sign

that was outside the absolute value.

So we're left with -(14) or -14.

Lori rented a car for one day. The daily rental rate was $12.50 plus 25 cents per mile. The total cost of her rental was $46. Ho

Leona [35]

Answer:

The number of miles Lori drive be 134 miles .

Step-by-step explanation:

Let us assume that the number of miles Lori be x.

As given

Lori rented a car for one day.

The daily rental rate was $12.50 plus 25 cents per mile.

As 1 dollar = 100 cent

$1\ cent = \frac{1}{100}\ dollar$

$25\ cent = \frac{25}{100}\ dollar$

$25\ cent = 0.25\ dollar$

As given

The total cost of her rental was $46.

Than the equation becomes

46 = 12.50 + 0.25x

46 - 12.50 = 0.25x

33.5 = 0.25x

$x = \frac{33.5}{0.25}$

x = 134 miles

Therefore the number of miles Lori drive be 134 miles .

Solve each equation using the quadratic formula. Find the exact solution, then approximate the solution to the nearest hundredth

Anika [276]

Answer:

$x_1=\frac{5+\sqrt{33}}{4}$ ≈2.69

$x_2=\frac{5-\sqrt{33}}{4}$ ≈-0.19

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

1. You have that the quadratic formula is:

$x=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

2. To solve the quadratic equation you must substitute the values. So, you have that:

Rewrite the equation:

$2x^{2}-5x-1=0$

$a=2\\b=-5\\c=-1$

Then you have:

$x=\frac{-(-5)+/-\sqrt{(-5)^{2}-4(2)(-1)}}{2(2)}$

3. Therefore, you obtain the following result:

$x_1=\frac{5+\sqrt{33}}{4}$ ≈2.69

$x_2=\frac{5-\sqrt{33}}{4}$ ≈-0.19

Answer:

75 - 52.5 = x

Step-by-step explanation:

$\because 52.5 + x = 75\\\therefore x = 75 - 52.5\\\therefore 75 - 52.5 = x \\$

is the correct answer.
