Answer:

Step-by-step explanation:

If you imagine the dots continued in a connected line, (imagining where the data points will likely go), the line's slope informs you if it is a negative (going down/negative slope) linear association or if it's a positive (going up/positive slope) linear association.

For A, it has a positive slope [as it increases].

For B, it also has a positive slope

For C, there is no correlation, the dots are not showing any trends

For D, there is a negative slope.

This means that the scatter plot D shows a negative linear association.

Help me solve this equation and show work 11d + 17b = 95 d + b = 7

sweet-ann [11.9K]

Answer:

{d,b}={4,3}

Step-by-step explanation:

[1] 11d + 17b = 95

[2] d + b = 7

Graphic Representation of the Equations :

17b + 11d = 95 b + d = 7

Solve by Substitution :

// Solve equation [2] for the variable b

[2] b = -d + 7

// Plug this in for variable b in equation [1]

[1] 11d + 17•(-d +7) = 95

[1] -6d = -24

// Solve equation [1] for the variable d

[1] 6d = 24

[1] d = 4

// By now we know this much :

d = 4

b = -d+7

// Use the d value to solve for b

b = -(4)+7 = 3

Solution :

{d,b} = {4,3}

Alex73 [517]

Answer:

Step-by-step explanation:

The angles labeled 4y - 8 and 79 + y are called vertical angles, and definition, vertical angles are congruent. That means algebraically, that

4y - 8 = 79 + y and

3y = 87 and

y = 29

Which graph shows the solution to this system of inequalities? y>-1/3x+1 y>2x-3

Mademuasel [1]

Given:

The system of inequalities is:

$y>-\dfrac{1}{3}x+1$

$y>2x-3$

To find:

The graph of the given system of inequalities.

Solution:

We have,

$y>-\dfrac{1}{3}x+1$

$y>2x-3$

The related equations are:

$y=-\dfrac{1}{3}x+1$

$y=2x-3$

Table of values for the given equations is:

$x$ $y=-\dfrac{1}{3}x+1$ $y=2x-3$

0 1 -3

3 0 3

Plot (0,1) and (3,0) and connect them by a straight line to get the graph of $y=-\dfrac{1}{3}x+1$ .

Similarly, plot (0,-3) and (3,3) and connect them by a straight line to get the graph of $y=2x-3$ .

The signs of both inequalities are ">". So, the boundary line is a dotted line and the shaded region or each inequality lie above the boundary line.

Therefore, the graph of the given system of inequalities is shown below.

A, O and B lie on a straight line segment.

Dafna11 [192]

Answer:

x = 36

Step-by-step explanation:

the 3 angles form a straight angle and sum to 180°

sum the 3 angles and equate to 180

3x + x + x = 180 , that is

5x = 180 ( divide both sides by 5 )

x = 36
