Answer:

x=17

Step-by-step explanation:

you have to use the 2 secants rule

8(8+13) = 7(7+x) distribute in parenthesis

64+ 104 = 49 +7x  isolate variable

64+104-49 = 7x combine like terms

119 =7x divide both sides by 7

17 =x

Answer: [tex]184,724.153[/tex]

Step-by-step explanation:

Given

In 1990, there were 1200 cell phone subscriber in small town of stephenville

It is increasing by 75% per year after 1990

In year 1991 it is

[tex]\Rightarrow 1200+1200\times 0.75\\\Rightarrow 122(1.75)[/tex]

In year 1992 it is

[tex]\Rightarrow 1200(1.75)+1200(1.75)\times 0.75\\\Rightarrow 1200(1.75)(1+0.75)\\\Rightarrow 1200(1.75)^2[/tex]

So, it is increasing as [tex]1200(1.75)^x[/tex]

where [tex]x=[/tex]no of years spent

After 9 years, it is

[tex]\Rightarrow 1200(1.75)^9=184,724.153[/tex]

Answer:

Answer:

Step-by-step explanation:

The first thing they did was factor the denominators

so

x²-3x+2= (x-1)(x-2)

and

x²-1= (x-1)(x+1)

To add two fractions their denominators need to be the same

to accomplish this they mulitpied both sides of the fraction

after that they mulitplied what was in the numerator and combined like terms

Because the denominator cannot equal 0 x≠ -1, 1, 2

Answer:

The answer is 9/10

Step-by-step explanation:

8/10 is the same thing as ⅘, ⅘ is just simplified

⅖ is less than ⅘ so it would come before c

6/5 is more than 1 so it wouldn’t be on that number line.

Answer:

OK.

My answer is based on 2 things.

1. That the furthest point on the left is 0( That other little distance is ignored)

2. That the point C is equidistant from 4/5 and 1.

If so..

Then

4/5 + x + x =1

4/5 +2x = 1

2x= 1-4/5

x=1/10

Now

From 4/5 to C is x...

Then Position C would be

4/5 + 1/10

c= 9/10

Or by simply making guesses...

All Other options are greater than 1... So It can't be those cos C is less than 1

X is 6,y is 4

Answer:

42.5 square.cm

Step-by-step explanation:

Find the diagram attached

Area of the shaded portion = area of square - area of circle

Area of square = L²

Area of square = 11 × 11

Area of square = 121 square centimetres

Area of circle = pir²

r is the radius of the circle = 5cm

Area of the circle = 3.14×5²

Area of the circle = 3.14×25

Area of the circle = 78.5 square. cm

Area of the shaded region = 121 - 78.5

Area of the shaded region = 42.5 square.cm

Step-by-step explanation:

Answer:

A; (4,4), (8,8) and (12,16)

Step-by-step explanation:

The value x starts with 4 and add 4 to each term

The value y start with 4 and each term next is multiplied by 2

So for x, we have;

4 , (4 + 4) and (4 + 4 + 4)

= 4,8 and 12

For y;

we have ;

4, (4 * 2) , (4 * 2 * 2)

= 4, 8, 16

so pairing up, we have;

(4,4), (8,8) and (12,16)

Answer:

the total no of points score in the 2 games is 10 points

Step-by-step explanation:

Given that

She made 3 points in her first game and her second game

Also, she made 2 point shots in each game

we need to find out the no of total points did she score in the 2 games

So,

The number of total points is

= 3 + 3 + 2 + 2

= 10 points

Hence, the total no of points score in the 2 games is 10 points

Answer:

f(x) = 2x(x - 8)

f(x) = 2(x - 2)² - 8

Step-by-step explanation:

Let the equation of the quadratic function is,

f(x) = a(x - h)² + k

Here, (h, k) is the vertex of the function.

From the graph attached,

Vertex of the parabola → (2, -8)

Therefore, equation of the function will be,

f(x) = a(x - 2)² - 8

Since, the graph passes through origin (0, 0),

f(0) = a(0 - 2)² - 8

0 = 4a - 8

a = 2

Equation of the given parabola will be,

f(x) = 2(x - 2)² - 8

      = 2(x² - 4x + 4) - 8

      = 2x² - 8x + 8 - 8

      = 2x² - 8x

      = 2x(x - 8)

Therefore, factored form of the function will be,

f(x) = 2x(x - 8)

Answer:

8.5 = $35,000

2% = $18,000

Step-by-step explanation:

two equations can be derived from the question

x + y = $53,000 equation 1

0.02x + 0.085y = $3,335.00. equation 2

x = amount invested in 2% bond

y =  amount invested in 8.5% bond

multiply equation 1 by 0.02

0.02x + 0.02y = 1060 equation 3

subtract equation 2 from 3

0.065y = 2275

y = 35,000

substitute for y in equation 1

53,000 - 35,000 = 18,000
