Answer:

-64.

Step-by-step explanation:

f(x)=-x^2-4x-19            Replacing x by -9:-

f(-9)= -(-9)^2-4(-9)-19

= -81 + 36 - 19

= 36 - 100

= -64.

Answer:

-64

Step-by-step explanation:

f(x)=-x^2-4x-19

Let x = -9

f(-9) = - (-9)^2 -4(-9) -19

     = -81 +36 -19

     =-64

Answer:

D.

Step-by-step explanation:

The first step is to subtract 2 on both sides, so

3(y - 5) + 2 - 2 = 5 - 2

3(y - 5) = 3

Next, multiply by or distribute the 3 on the left side.

3y - 15 = 3

Then, add 15 on both sides.

3y - 15 + 15 = 3 + 15

3y = 18

Finally, divide by 3 on both sides.

3y/3 = 18/3

y = 6

Using location of points and a system of equations, it is found that:

----------------------------------

Point C is located between points B and D means that:

[tex]BD = BC + CD[/tex]

----------------------------------

We are given that:

From this, two equations can be built.

[tex]2x + 8y = 38[/tex]

Dividing both sides by 2:

[tex]x + 4y = 19[/tex]

[tex]x = 19 - 4y[/tex]

----------------------------------

Finding y:

[tex]BC + CD = BD[/tex]

[tex]5x + 7 + 3y + 4 = 38[/tex]

[tex]5x + 3y + 11 = 38[/tex]

[tex]5x + 3y = 27[/tex]

Since [tex]x = 19 - 4y[/tex]

[tex]5(19 - 4y) + 3y = 27[/tex]

[tex]95 - 20y + 3y = 27[/tex]

[tex]17y = 68[/tex]

[tex]y = \frac{68}{17}[/tex]

[tex]y = 4[/tex]

----------------------------------

Finding x:

[tex]x = 19 - 4y = 19 - 4(4) = 19 - 16 = 3[/tex]

The value of x is 3.

The value of y is 4.

Answer:

Step-by-step explanation:

Square footage is calculated by multiplying width by length. So if a room is 18 foot wide by 10 foot long, 18 x 10 = 180 square feet.

Answer:

M.  2.5n - (-8.2) = 26. 7

to find n transpose

2.5n + 8.2 = 26. 7

2.5n = 26. 7 - 8.2

2.5n = 18.5

n = 18.5 ÷ 2.5

n = 7.4

L.  [tex]\frac{7a + 1}{2}[/tex] = 18

7a + 1 = 18 ×2

7a + 1 = 36

7a = 36 - 1

7a = 35

a = 35 ÷ 7

a = 5

N.     [tex]\frac{2}{5}[/tex] b + 1 = -11

[tex]\frac{2}{5}[/tex] b   = -11 -1

b = -12 - [tex]\frac{5}{2}[/tex]

b = 20

Answer:

-3

Step-by-step explanation:

Adding a negative number is like subtracting. Subtracting more than the original positive number gets you in to the negative numbers.

Problem 5

Answer: Yes the points are coplanar

------------------------

Explanation:

Note how all four points are in the same plane, aka face, along the top of the 3D block. The term "coplanar" simply means "all in the same plane", so that's why the points are coplanar.

In contrast, the set of points {H,J,K,Z} are not all coplanar because H,J,K are in the top plane, while Z is not.

Problem 6

Answer: line segments WX, XY, and XK

------------------------

Explanation:

All three lines mentioned above involve the letter X in some fashion. The order doesn't matter. Also, those lines intersect at the common point X.

===========================================================

Problem 7

Answer: point W

------------------------

Explanation:

The plane WXYZ is the bottom face, in which we can think of as the floor of the building. The segment HW is from the floor and goes up vertically. We can consider this to be like a pole beam of the structure. The plane and segment both have point W in common. Note that the letter "W" is found in the sequences WXYZ and HW, and it's the only common letter.

===========================================================

Problem 8

Answer: The points are not collinear

------------------------

Explanation:

To be collinear, the points must all be on the same straight line. We see that isn't the case with points W, X and Y.

Answer:

A constant you need to find when given what the equation is equal to.

Answer:

Here, 'd' is the variable of 2.

Answer: 8 hours

Step-by-step explanation:

Given information

Admission fee = $7.00

Hour rent fee = $1.50

Number of hours = h

Total fee = $19

Set equation according to the given information

Total fee = admission fee + (hours) × (hour rend fee)

Substitute values into the equation

19 = 7 + 1.5h

Subtract 7 on both sides

19 - 7 = 7 + 1.5h - 7

12 = 1.5h

Divide 1.5 on both sides

12 / 1.5 = 1.5h / 1.5

[tex]\boxed{h=8}[/tex]

Answer:

53.931339977852% (you can round)

Step-by-step explanation:

You add up 48,700 and 41,600 and you would get 90,300 as the overall population. Then you would put it in fraction form if you want to convert it into a percentage. The fraction form would be 48,700/90,300. You could simplify it to 487/903. Then you do  487            x      . You would cross multiply and get

                                              ___    =    ___

                                              903           100

903x = 48700. Then you would divide each side by 903 and get x = 53.931339977852% (you can round)

Answer:

Approximately 53.9%

To be exact, answer is 48700/903

Step-by-step explanation:

Percentage of men = Men ➗ Total population

48700 + 41600 = 90300

48700/90300 is approximately 0.539

0.539 * 100 = 53.9

Step-by-step explanation:

In this problem, you need to find out how many total legs 8 ants would have together. Each ant has 6 legs; this means that to solve you must add 6 together 8 times. However, there is an easier way to do this. You can also multiply 6 by 8 to get the same answer. The answer is 48.
