Answer:

8x - 7 + 12x after being simplified would be 20x - 7

Step-by-step explanation:

Add 8x and 12<em>x</em>.

8 + 12 = 20<em>x</em>

20<em>x</em> - 7 would be your answer.

Hope this helps!

Find the equation of the line. Use exact numbers. y=y=y, equals x+x+x, plus
Nuetrik [128]

The equation of a line that is passing through the points (0, 4) and (1, 6) will be y = 2x + 4.

<h3>What is the linear system?</h3>

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A coordinate plane. The x-axis and y-axis are each scaled by one.

A graph of a line goes through the points (0, 4) and (1, 6) will be

The equation of a line that is passing through the points (0, 4) and (1, 6) will be

y - 4 = [6 - 4 / 1 - 0] (x - 0)

y - 4 = 2x

    y = 2x + 4

The graph is given below.

More about the linear system link is given below.

The graph below plots the values of y for different values of x: (look at graph picture)
Dima020 [189]

Answer:

A: x and y have a strong, positive correlation

Step-by-step explanation:

Correlation coefficient measures the relation between   two variable.

it signifies how the value of one variable will change when the change in other variable is made.

Its value ranges from 0 to 1

  1. 0 represent no relation
  2. 1 represent strong relation

thus, as value increases from 0 to 1 , correlation strength increases.

Correlation coefficient can be negative and positive

  1. negative relation signifies that as value of one variable increases then the value of other will decrease and vice-versa
  2. positive relation signifies that as value of one variable increases then the value of other will also increase and vice versa

Given, that correlation coefficient between x and y  is  0.9

since there is no negative sign it means there is positive correlation

value is 0.9

as 0.9 is nearer to  1, it is clear that relation is strong.

based on above discussion

option A

 x and y have a strong, positive correlation is correct answer

If we look at graph we can see that as x increases y also increases.

the rate of increase of value of y in response of x is also high.

Thus, graph also shows that there is strong positive correlation

13. Describe the system by substitution:<br> y=x-7<br> 2x - y = 3
torisob [31]

Answer:

x = y + 7 \\  \\ x =  \frac{3 + y}{2}  \: or \: y = 2x - 3

Step-by-step explanation:

1. \: 2x = 3 + y \\ 2. \: x =  \frac{3 + y}{2}  \: or \: y = 2x - 3 \\  \\ 1. \: y + 7 = x \\ 2. \: x = y + 7
