Given f(x) = -x - 1, find f(1).

The expression that shows number of remote control cars on the display self is 16s.

Mathematical expressions are formed using at least two numbers,  variables, and there must be one arithmetic operation, and a statement. If there are x items are given in one self and there are n number of self and we have to find total number of items in all self, then we have to multiply x by n.

Here, there are 16 remote control cars on a display self. The number of display shelves is s.

So, the total number of cars will be 16 times of s.

Number of cars on display = 16s

Therefore, the expression that shows the number of cars on display is 16s.

z = 134 (number of mezzanine units sold)

b = 834 (number of balconies sold)

m = 1120 (number of main floor sales)

Equations:

60m + 42b + 40z = 107,588

m = b + z + 152

b = 3z + 432

Substitute for "b" to get m = 4z + 584

------

Substitute for m and b and solve for "z"::

60(4z+584) + 42(3z+432) + 40z = 107588

240z + 35040 + 126z + 18144 + 40z = 107588

406z + 53184 = 107588

406z = 54404

z = 134 (# of mezzanine sold)

Solve for "b" and for "m" using z = 134

b = 3(134) + 432

b = 834 (# of balcony sold)

m = 834 + 134 + 152

Answer:

For x = -2, y would equal -3.

For x = -1, y would equal -2.

For x = 0, y would equal -1.

For x = 1, y would equal 0.

For x = 2, y would equal 1.

Step-by-step explanation:

So what we have to do is plug in the x-values from the table into the equation.

1) y = -2 -1 => y = -3

2) y = -1 - 1 => y = -2

3) y = 0 - 1 => y = -1

4) y = 1 - 1 => y = 0

5) y = 2 - 1 => y = 1

Answer:

a)A=4B

b)A=20

c)B=9

If it is directly proportional it means that A=kB.

you can substitute the numbers to find k.

12=k3

k=4

so the formula is A=kB.

For part b and c it is just substitution

[tex]\sf \dfrac{-1}{2}[/tex]

Step-by-step explanation:

Find the slope:

(-9 , -5)   ⇒ x₁ = -9  ; y₁ = -5

(-1 , -9)   ⇒ x₂ = -1   ; y₂ = -9

[tex]\sf \boxed{Slope = \dfrac{y_2-y_1}{x_2-x_1}}[/tex]

           [tex]\sf = \dfrac{-9-[-5]}{-1-[-9]}\\\\\\=\dfrac{-9+5}{-1+9}\\\\\\=\dfrac{-4}{8}\\\\\\=\dfrac{-1}{2}[/tex]

Answer:

Slope = -1/2

Step-by-step explanation:

Formula we use,

→ (y2 - y1)/(x2 - x1)

Now the value of slope is,

→ (-9 -(-5))/(-1 -(-9))

→ (-9 + 5)/(-1 + 9)

→ -4/8 = -1/2

Hence, the slope is -1/2.

Answer:

  Isiah is correct. The slope is about 0.344.

Step-by-step explanation:

Lyra and Isiah want the slope of the hypotenuse in a triangle with an angle of elevation of 19°.

The slope is the ratio of "rise" to "run". In a right triangle, that is the ratio "opposite"/"adjacent". This ratio is the tangent of the angle of elevation.

  tan(19°) ≈ 0.344

The slope is about 0.344. Isiah is correct.

Isiah knows Lyra is not correct because the slope in a triangle with a 45° angle is 1. Lyra' value of 2.675 is about right for an angle of 69.5°, much greater than either 45° or the given angle of 19°.

Additional comment

Unfortunately, the diagram is not drawn to scale. This is often the case with diagrams in geometry problems. The diagram here is misleading in that it seems to show a slope greater than 1 for a 19° angle.

The largest area that may be surrounded by fencing is 61776.13 m².

A building's side will have a rectangular storage room built into it. The remaining three corners of the space need security fencing.

The maximum area is enclosed within 703ft of fencing.

Let x = width

     L = length

The perimeter with 3 sides;

L + 2x = 703

L = (703 - 2x)

Let, Area = x * L

Now, replace L with (703 - 2x);

A = x * (703 - 2x)

A = 703x - 2x²

To get the max area by finding the axis of symmetry;

x = -b/2a

In this equation a = -2; b = 703

x = -703 / (2*-2)

x = 175.75m, ( width for the max area )

To get the max area, x=175.75;

A = -2(175.75²) + 703(175.75)

A = -61776.12 + 123552.25

A = 61776.13 m² is a max area

Hence, The maximum area that can be enclosed with 703ft of fencing is 61776.13 m².

Which one of the following is NOT equivalent to 3/4?

15/20 = 3/4

6/8 = 2/3

24/32 = 3/4

Answer: 16/24 and 24/32 are not equivalent to 3/4

Step-by-step explanation:

Equivalent fractions represent the same value, even though they look different.

Here, when we convert every fraction to its simplest form, we can verify if they are equal.

(16/24) ÷ (8/8) = 2/3

(15/20) ÷ (5/5) = 3/4

(6/8) ÷ (2/2) = 3/4

(24/32) ÷ (4/4) = 6/7
