Answer:

Two x's can have the same y, but an x cannot have different y's. For example, [(2,3)(-2,4)(3,3)(5,18)] is a function because all of the x's have a specific y, and there is not more than one y to an x. However, [(2,3)(-3,7)(2,-4)] is not a function because one of the x's has more than one y.

Answer:

The answer is <ACD = 68°

Step-by-step explanation:

Using the property that the sum of interior angles in a triangle is equal 180°,we have:

<DAC + <ACD + <ADC = 180°

[tex]2x + (180 - 4x) + 56 = 180 \\ - 2x + 56 = 0 \\ 2x = 56 \\ x = \frac{56}{2 } \\ x = 28[/tex]

Finally, calculating the angle <ACD, we have:

<ACD = 180 - 4x

<ACD = 180 - 4 . 28

<ACD = 180 - 112

ACD = 68°

Answer:

x = 28°

m∠ACD = 68°

Step-by-step explanation:

From inspection of the given diagram:

Vertical Angle Theorem

When two straight lines intersect, the vertical angles are congruent.

⇒ m∠DAC = m∠EAB = 2x

Angles on a straight line sum to 180°:

⇒ m∠ACD + 4x = 180°

⇒ m∠ACD + 4x - 4x = 180° - 4x

⇒ m∠ACD = 180° - 4x

Exterior Angle Theorem

The exterior angle of a triangle is equal to the sum of the two non-adjacent interior angles of the triangle.

⇒ m∠DAC + m∠ACD = m∠FDC

⇒ 2x + (180° - 4x) = 124°

⇒ -2x + 180° = 124°

⇒ -2x + 180° - 180° = 124° - 180°

⇒ -2x = -56°

⇒ -2x ÷ -2 = -56° ÷ -2

⇒ x = 28°

To find m∠ACD, substitute the found value of x into the expression for the angle:

⇒ m∠ACD = 180° - 4x

⇒ m∠ACD = 180° - 4(28°)

⇒ m∠ACD = 180° - 112°

⇒ m∠ACD = 68°

Answer:

No they don't (unless I messed up)

Step-by-step explanation:

([{3x=9} 2]=81) - ([{x=3}+1]=4) =77

([{2x=10} 2]=100) + {[(2x=25)-4]=21} = 79

Answer:

$16034.03

Step-by-step explanation:

I'm going to assume it's compound interest

10000(1+.083)^12

26034.03

subtract the original amount to find out how much was earned

26034.03-10000=16034.03

Answer:

$9960 would be earning in 12 years

Step-by-step explanation:

8.3% of 10,000 is 830

1% of 10,000 is 100

.3 would just be 30

.4 would be 40

etc etc

so 830 times 12(years) is $9960.00

Answer:

82,300

Step-by-step explanation:

last numbers is 345

so if 350 it would go to 400

but it is under so it goes to 300.

Answer:

1. Hundred is 82,300

2. Hundreths is 82,345.57

3. Tens is 82,350

4. Tenths is 82,345.6

Answer:

6(m-2)

Step-by-step explanation:

Alright. Let's start by finding the length of this shaded area. The full length of the rectangle is 'm', and the part that is not shaded has a length of '2', so if we subtract the full length and the non-shaded length, we will get the shaded part's length. This is 'm-2'. The width/height we already know...it is 6, so-

Answer is: 6(m-2)

Answer:

6(m-2)

Step-by-step explanation:

it is 6(m-2) because you would do the whole length of m minus 2.

Answer:

24:9 or 24 to 9 or [tex]\frac{24}{9}[/tex]

Step-by-step explanation:

The amount of plums is 24. The amount of apples is 9. So to write the ratio of plums (24) to apples (9), you write 24 to 9. You can either write a colon - 24:9 - a to - 24 to 9 - or as a fraction - [tex]\frac{24}{9}[/tex]. But, you have to write it with plums first.

Answer:

4/3x

Step-by-step explanation:

Answer:

11/6=x

Step-by-step explanation:

System of Linear Equations entered :

 [1]           y=5x-7

 [2]           -3x-3y=-12

Equations Simplified or Rearranged :

  [1]    y - 5x = -7

  [2]    -3y - 3x = -12

Graphic Representation of the Equations :

   -5x + y = -7        -3x - 3y = -12  

Solve by Substitution :

// Solve equation [1] for the variable  y  

 [1]    y = 5x - 7

// Plug this in for variable  y  in equation [2]

  [2]    -3•(5x-7) - 3x = -12

  [2]     - 18x = -33

// Solve equation [2] for the variable  x  

  [2]    18x = 33  

  [2]    x = 11/6  

// By now we know this much :

   y = 5x-7

   x = 11/6

// Use the  x  value to solve for  y  

   y = 5(11/6)-7 = 13/6  

Solution :

{y,x} = {13/6,11/6}

Answer:

12.66 cm

Step-by-step explanation:

Area of the circle = 125.8 Sq cm

[tex] \therefore \: \pi {r}^{2} = 125.8 \\ \\ \therefore \: 3.14 \times {r}^{2} = 125.8 \\ \\ {r}^{2} = \frac{125.8}{3.14} \\ \\ {r}^{2} = 40.0636943 \\ \\ {r} = \sqrt{40.0636943} \\ \\ r = 6.32958879 \\ \\ r \approx \: 6.33 \: cm \\ \\ d \: = 2r \\ \\ d = 2 \times 6.33 \\ \\ d = 12.66 \: cm \\ [/tex]

Diameter of the circle = 12.66 cm

Since, circumference of the circle touches each of the four sides of the square.

So, length of the sides of the square

= diameter of the circle.

= 12.66 cm
