The slope of the graph is $15 per hour. The linear function is given by y = 15x

What is a linear function?

A linear function is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept

The graph passes through the point (1, 15) and (8, 120) is:

y - 15 = [(120 - 15)/(8 - 1)(x - 1)

y = 15x

For 20 hours; y = 15(20) = $300

If the person got a $50 bonus and also worked some hours, the graph would change because the y intercept would be 50.

If the person got a $2 per hour rate, the graph would change because the slope would be 2.

The slope of the graph is $15 per hour.

Write the slope-intercept for of the equation of the line with that passes through the point (2,-8) and is perpendicular to 2x+3y=15

Answers

Answer:

y = 3/2 x - 11

Step-by-step explanation:

Recall that a perpendicular line to the expression:

2 x + 3 y = 15

3 y = - 2 x + 15

y = - 2/3 x + 15/3

is going to have a slope equal to the opposite of the reciprocal of the original (-2/3) slope. So, the slope of the perpendicular line must be: 3/2.

We use this value in a general point-slope form of a line, where we use the point (2, -8) :

y - (-8) = 3/2 (x - 2)

y + 8 = 3/2 x - 3*2/2

y + 8 = 3/2 x - 3

y = 3/2 x - 3 - 8

y = 3/2 x - 11

Answer:

30 in³

Step-by-step explanation:

surface area = 2(2 * 5 + 5 * u + 2 * u) = 62

2(10 + 5u + 2u) = 62

2(10 + 7u) = 62

10 + 7u = 62/2 = 31

7u = 31 - 10 = 21

Find the 47th term.

Answers

This is an arithmetic sequence with a common difference given by d= -7

I will start by defining my first term as u⁰=361

Now we have to think, if u⁰ is my 1st term than my 47th term would be u⁴⁶ not u⁴⁷ since i start counting from 0 and not 1.

Using the relation that describes the implicit relation of an arithmetic sequence, i can say:

u(n)=u⁰+nd where n is any number

u⁴⁶=u⁰+46d

u⁴⁶=361+46(-7)

u⁴⁶=361-322

u⁴⁶=39

Answer:

39.

Step-by-step explanation:

This is an arithmetic sequence with common difference -7

47th term = a + d(n - 1)

= 361  - 7(47-1)

= 39.

Yet we could not recognize the right that the state of Mississippi had assumed, to legislate for us.Although the legislature of the state were qualified to make laws for their own citizens, that did not qualify them to become law makers to a people that were so dissimilar in manners and customs as the Choctaws are to the Mississippians. Admitting that they understood the people, could they remove that mountain of prejudice that has ever obstructed the streams of justice, and prevent their salutary influence from reaching my devoted countrymen. We as Choctaws rather chose to suffer and be free, than live under the degrading influence of laws, which our voice could not be heard in their formation.
