A)
6x + 4x - 6 = 24 + 9x
10x - 6 = 24 + 9x
2x = 24 + 6
x = 15

x has one solution.

b)
25 - 4x + 15 - 3x + 10 - x = ?

x has no solution.

c)
4x + 8 = 2x + 7 + 2x - 20
0x = -13 - 8
0x = -21

x is undefined.
x ≠ ∞ or x ≠ -∞

∴ x has no solution.

The ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda is 7 : 1 ⇒ 3rd answer

Step-by-step explanation:

In A graph:

Points are shown on ordered pairs (0 , 0) , (1 , 7) , (2 , 14) , (3 , 21) and (4 , 28) are connected by a line
The label on the x-axis is Lemon-Lime Soda in cups
The label on the y-axis is Strawberry Juice in cups

We need to find the ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda

∵ The points are connected by line

∵ The x-axis represents the number of cups of Lemon-Lime Soda

∵ The y-axis represents the number of cups of Strawberry Juice

∴ The ratio of the the number of cups of strawberry juice to the

number of cups of lemon-lime soda equal to the slope of the line

∵ The slope of the line $m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

- You can calculate the slope of a line from any two points lie on it

∵ Points (1 , 7) and (2 , 14) lie on the line

∵ $x_{1}$ = 1 and $x_{2}$ = 2

∵ $y_{1}$ = 7 and $y_{2}$ = 14

∴ $m=\frac{14-7}{2-1}=\frac{7}{1}$

∵ The ratio of the number of cups of strawberry juice to the number

of cups of lemon-lime soda = m

∴ The ratio of the number of cups of strawberry juice to the number

of cups of lemon-lime soda = 7 : 1

The ratio of the number of cups of strawberry juice to the number of cups of lemon-lime soda is 7 : 1

An experiment consists of choosing objects without regards to order. Determine the size of the sample space when you choose the

sdas [7]

Answer:

$n= 75, 582$

$n= 2300$

$n = 253$

Step-by-step explanation:

Generally the size of the sample sample space is mathematically represented as

$n = \left N } \atop {}} \right. C_r$

Where N is the total number of objects available and r is the number of objects to be selected

So for a, where N = 19 and r = 8

$n = \left 19 } \atop {}} \right. C_8 = \frac{19 !}{(19 - 8 )! 8!}$

$= \frac{19 *18 *17 *16 *15 *14 *13 *12 *11! }{11 ! \ 8!}$

$n= 75, 582$

For b Where N = 25 and r = 3

$n = \left 25 } \atop {}} \right. C_3 = \frac{25 !}{(19 - 3 )! 3!}$

$= \frac{25 *24 *23 *22 ! }{22 ! \ 3!}$

$n= 2300$

For c Where N = 23 and r = 2

$n = \left 23 } \atop {}} \right. C_2 = \frac{23 !}{(23 - 2 )! 2!}$

$= \frac{23 *22 *21! }{21 ! \ 3!}$

$n = 253$
