1. A debit signifies something owed. So, that means the answer is negative.

-$40

2. A deposit means you are gaining money. So, the answer is positive.

+$225

3. Above sea level signifies to us it is above zero. So, the answer is positive.

+14000 feet

(Keep in mind, whenever they say above, it is always positive.)

4. The temperature increased, meaning that it is positive.

+40°F

5. Withdrawl implies losing money. So, the answer is negative.

-$225

6. Below sea level implies it is below zero. So, the answer is negative.

-14000 feet

Which is the graph of f(x) = -(x + 3)(x + 1)?

Bas_tet [7]

Answer:

See attachment

Step-by-step explanation:

A function is given to us and we need to tell which graph represents the given function. The function given to us is,

$\tt: \implies f(x) = -( x + 3 )( x + 1 )$

Let's find out at which points do the graph Intersects x axis / finding the roots. For that substitute f(x) = 0 , we have ,

$\tt: \implies -(x +3)( x + 1 ) = 0$

Equate each factor by 0 ,

$\tt: \implies \boxed{\blue{ \tt x = -1,-3 }}$

Therefore the graph will intersect x axis at x is equal to -1 and x is equal to -3 .

On looking at the given graphs in the options the second graph intersects x axis at -1 and -3 .

Hence the second option is correct .

A circle had a sector with area 33pi and central angle of 11/6pi radians

MissTica

Answer:

The area of the circle is $36\pi\ units^{2}$

Step-by-step explanation:

we know that

The area of a circle subtends a central angle of $2\pi$ radians

so

By proportion find the area of the circle

$\frac{33\pi }{(11\pi /6)}=\frac{x}{2\pi}\\ \\ x=2\pi*( 33*6)/11\\ \\x=36\pi\ units^{2}$

Can someone answer this if you don’t mind

allsm [11]

4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.

Thus, 11x - 18 = 180 degrees.

Combining like terms, 11x = 198, and x = 18.

The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.

Can anyone help me pls ( if you can, can you do it on paper and post it with the answer)

<h2>Answer: x = 6</h2>

* = things that have changed or are being changed

<h2>Explanation:</h2>

1. rearrange terms

*4 4 + 3 * = 5 + 2 + 2 0

*3x + 44* = 5x + 2 + 20

2. combine like terms

3 + 44 = *5x + 2* + 20

3 + 44 = *7x* + 20

3. Subtract 4 4 from both sides of the equation

3x + 44 = 7x + 20

3x + 44 *-44* = 7x + 20 *-44*

4. Simplify

(Subtract the numbers)

3x + *44 - 44* = 7x + 20 - 44

3x = 7x + 20 - 44

(Again)

3x = 7x + 20 *- 44*

3x = 7x - 24

5. Subtract 7 from both sides of the equation

3x = 7x - 24

3x *- 7x* = 7x - 24 *- 7x*

6. Combine like terms

*3x - 7x* = 7x - 24 - 7x

*-4x* = 7x - 24 - 7x

(Again)

-4x = *7x* - 24 *- 7x*

-4x = - 24

7. Divide both sides of the equation by the same term

-4x = - 24

$\frac{-4x}{*-4*} = \frac{-24}{*-4*}$

8. Simplify

(Cancel terms that are in both the numerator and denominator)

$* \frac{-4x}{-4} * = \frac{-24}{-4}$

*x* = $\frac{-24}{-4}$

(Divide the numbers)

x = $\frac{-24}{-4}$

x = 6
