Answer:

NO SOLUTION

Step-by-step explanation:

Solve this system by substitution:

Replace y in the first equation with -2x - 2:

2x + (-2x - 2) = 2, or

2x - 2x - 2 = 2

0 = 4 This is not possible, so this system has NO SOLUTION.

Which statement is true about the graphs of the two lines y = –6 and x = 1/6<br>?

ivanzaharov [21]

The lines are perpendicular to each other because the graph of y = –6 is a horizontal line with a slope that is undefined, and the graph of x = 1/6 is a vertical line with a slope of 0.

Explain how a(b + c ) can rewritten as (b + c) and as ba + ca

mart [117]

Answer:

The distributive property makes it possible

Step-by-step explanation:

Step one:

given the expression a(b + c )

the first step is to open the bracket, that is multiply all the terms in the bracket by a, so multiply b by a and c by a also.

Step two:

Thus, this property is called the distributive property of multiplication

a*b+ca

Answer: mean = 10.3 and median = 9.5

Step-by-step explanation:

Given data :

22, 14, 8, 1, 9, 0, 31, 2, 13, 3, 11, 10

Mean = $\dfrac{\text{Sum of all data values}}{\text{No. of data values}}$

$=\dfrac{22+14+8+1+9+0+31+2+13+3+11+10}{12}$

$=\dfrac{124}{12}=10.3$

Median = Middle most value.

For Median , we first arrange the data values in an order.

0 , 1 , 2, 3, 8, 9, 10 , 11, 13 , 14, 22, 31

Since , number of data values is 12 ( even) , so the median would be the mean of the two middlemost value.

i.e . Median= $\dfrac{9+10}{2}=9.5$

Hence, the mean and median of this distribution (in years) are :

mean = 10.3 and median = 9.5

First we solve for y₁
3×5 - 5y₁ = 20
15 - 5y₁ = 20
-5y₁ = 20 - 15
-5y₁ = 5
y₁ = -1
(5, -1)

Now we solve for x₂
3x₂ - 5×2 = 20
3x₂ - 10 = 20
3x₂ = 20 + 10
3x₂ = 30
x₂ = 10
(10, 2)
