Determine whether the graph represents a proportional or non-proportional relationship. Then select the correct equation in the form y=mx or y=mx+b to represent the relationship between the independent and dependent quantities.


This graph is an example of a blank area relationship. The equation that represents the relationship between the independent and dependent quantities is blank area.

Answers

Answer:

Non-proportional

y = [tex]\frac{2}{15}x+20[/tex]

Step-by-step explanation:

If a line doesn't pass through the origin relationship represented by the line is non proportional.

In other words, any line having y-intercept is non-proportional.

From the graph attached,

Line has a y-intercept = 20

Therefore, relationship is non-proportional.

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Since, the given line is passing through (0, 20) and (60, 28),

Slope of the line 'm' = [tex]\frac{28-20}{60-0}[/tex]

m = [tex]\frac{8}{60}[/tex]

   = [tex]\frac{2}{15}[/tex]

y-intercept 'b' = 20

Slope-intercept form of the equation is,

y = mx + b

So the equation will be,

y = [tex]\frac{2}{15}x+20[/tex]

The model below represents 4 x + (negative 4) = negative 2 x + 8.

4 long green tiles and 4 square red tiles = 2 long red tiles and 8 square green tiles.

What is the value of x when solving the equation 4 x + (negative 4) = negative 2 x + 8 using the algebra tiles?
x = negative 4
x = negative 2
x = 2
x = 4

Answers

Answer:

x = 2

Step-by-step explanation:

4 x + (negative 4) = negative 2 x + 8

4x + (-4) = - 2x + 8

4x - 4 = - 2x + 8

4x + 2x = 8 + 4

Which graph is and is not a function!?​

Answers

Answer:

The first one is a function. The other two are not functions.

Step-by-step explanation:

To find this, you use the vertical line test. If the vertical line touches multiple points on the graphed line, it is not a function. If the vertical line only touches the graphed line at one point, it is a function.

Ella bought some key chains and spent a total of $15. Each key chain cost the same whole-dollar amount. She bought between 4 and 9 key chains. How many key chains did Ella buy? Ella bought key chains

Answers

Answer:

5

Step-by-step explanation:

Total amount spent = $15

Number of chain purchased is between 4 and 9

Cost per chain is a the same (whole dollar)

Number of Chain purchased = (total cost / cost per chain)

Since the total cost = $15

The only whole number value which can divide $15 without a remainder and give a value between between 4 and 9 is 3.

Therefore, cost per chain = $3

Hence, number of chain purchased = $15 / $3

= 5

Answers

Answer:

the slope of each trend line

Step-by-step explanation:

The rate of change of the variables (dependent and independent) in the linear model is given by the slope or gradient of the regression model usually represented as :

y = bx + c ; where b is the slope and gives the change in y per change in the value of x.

Hence, when intending to find the rate of change of different Datasets, the slope of the trend line corresponding to each dataset is compared in other to determine the identify the differences in the rate of change of each dataset.

Aluminum and tin are both metals. The standard atomic weight for aluminum is 26.98. The standard atomic weight for tin is 118.71.Estimate the difference between the standard atomic weights of these two metals

Answers

Answer:

92

Step-by-step explanation:

To estimate the difference between the standard atomic weights of these two metals we round up the given weights to the nearest whole number

The standard atomic weight for aluminum is 26.98.

To the nearest the whole number = 27

The standard atomic weight for tin is 118.71

To the nearest whole number = 119

Hence,

The estimated difference = 119 - 27

= 92

Which statements are true about function g?

Function g is increasing over the entire domain.
As x approaches negative infinity, approaches positive infinity.
Function g includes an exponential piece and a quadratic piece.
As x approaches positive infinity, approaches positive infinity.
Function g is continuous.

Answers

Answer:

B, D, and E.

B: As x approaches negative infinity, g(x) approaches positive infinity.

D: As x approaches positive infinity, g(x) approaches positive infinity.

E: Function g is continuous.

Step-by-step explanation:

To answer this question, we will graph it. Please refer to the graph below.

Let’s go through each of the answer choices.

A) Function g is increasing over the entire domain.

Looking at the graph, we can see that this is not true.

More specifically, the red curve is decreasing over its entire interval.

So, A is not correct.

B) As x approaches negative infinity, g(x) approaches positive infinity.

This is true. As x approaches negative infinity i.e. as we go towards the left of the graph, we can see that our function g(x) (the red curve) is approaching positive infinity.

C) Function g includes an exponential piece and a quadratic piece.

This is false. The first piece is indeed exponential, but the second piece is a cubic, not a quadratic.

D) As x approaches positive infinity, g(x) approaches positive infinity.

Again, this is true. As x approaches positive infinity i.e. As we go towards the right of the graph, we can see that our function g(x) (the blue curve this time) is approaching positive infinity.

E) The function is continuous.

For a function to be continuous, it must have no breaks, jumps, and/or gaps.

We can see that our function does not possess any of the above.

So, g(x) is continuous.

Therefore, the correct statements are B, D, and E.
