this equation is in slope intercept form following the template of y=mx+b

because m is your slope, looking at the corresponding parts tells you 4/5 is the slope

Answer: 4/5

Step-by-step explanation: This equation is written in slope-intercept form which is more commonly known as y = mx + b form where the m or the coefficient of the x term represents the slope of the line and the b or the constant term represents the y-intercept of the line.

By looking at this linear equation, we can confirm that the slope

will be equal to 4/5 since it's the coefficient of the x term.

when adding two rational numbers tell what the sign of the sum will be if one rational number is positive and one is negative

Mekhanik [1.2K]

Answer:

True

Answer:

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

The relation is a function.

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component and different second components.

Remember that a function can only take on one output for each input. We cannot plug in a value and get out two values.

The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

I did the Vertical Line Test on your given graph. As you can see from the attached screenshot, each vertical line crosses the graph only once. Therefore, the given relation is a function.

The domain of the given relation is the set of x-values, while the range is the set of y-values. You'll have to list the ordered pairs in order to determine the domain and range of the given relation.

Relation: {(-4, -1), (-2, 1), (1, -2), (2, 4), (4, -4)}.

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

Find the value of x such that the data set has the given mean. 98, 123, 105, 114, 109, x ; mean 113 x = (Type an integer or a de

kotykmax [81]

Answer: 129

Step-by-step explanation:

the mean is the average of the data. including x, there are 6 data points

average = total/6

average = (98 + 123 + 105 +114 +109 + x) / 6

113 = (98 + 123 + 105 +114 +109 + x) / 6

113 = (549+ x) / 6

678 = 549 + x

x = 129

A test is worth 140 points. Ten percent of those points are from one short-answer question. How many points is the short-answer

Vlada [557]

If the total amount of points in a test is 140, and we want to find 10% of those points, we can do the following to figure out how much points the question is worth...

140 points x 10% = 140 x 0.1 = 14 points for the short-answer quesion.
