Answer:

I got x <= 8/7 which is none of the answer options given. Ask your professor about that.

Step-by-step explanation:

7x-1 <= 7

add 1 on each side

7x <= 8

Divide by 7 on both sides

7x/7 <= 8/7

Final answer

x <= 8/7

Answer:

Option #1, 3 and 4

Step-by-step explanation:

7x - 1 <= 7

Let's try them one by one:

1)

x <= -1

-7 - 1 = -8 is less than or equal to 7: True

There could be multiple answers, so let's do the other ones:

2)

x <= 4

28 - 1 = 27 <= 7: False

3)

x <= 1

7 - 1 = 6 <= 7: True

4)

x >= -1

-7 - 1 <= 7

-8 <= 7: True

Therefore, #1, 3, and 4 are correct.

write the equation of a line that is perpendicular to the line y=-6 and passes through the point (3,7)

Answers

Step-by-step explanation:

when two lines are perpendicular to each other( the product of their slope; m1m2 = -1)

m1 = -1/m2

m1 = -1/-6= 1/6

using the formula m= y-y1 / x - x1

1/6 = y -7 /x - 3

6(y -7) = x -3

6y -42 = x - 3

6y - x -39 =0

Divide both sides by 6

y - 1/6 x - 13/2= 0

y = 1/6 x + 13/2

Answers

(C) 180 mi
May be helpful for you

They must travel 125 miles farther before they stop for lunch and option A is the correct answer.

We have,

The total distance of the trip is 360 miles.

They plan to stop for lunch at the midpoint of the trip, which is

360 / 2 = 180 miles.

Now,

They have already travelled 55 miles this morning.

To find out how much farther they must travel before stopping for lunch, we subtract the distance travelled from the midpoint:

180 - 55

= 125 miles.

Thus,

They must travel A. 125 miles farther before they stop for lunch.

Jennifer pays $12.50 a month for Amazon Prime and pays extra every time she rents a movie. One month she rented 1 movie and paid $17.75. Another month she paid $49.25 and rented 7 movies.

Answers

Answer: y=5.25x+12.50

Step-by-step explanation:

The original 12.50 is how much she pays each month regardless of rented movies, it is the 0 value and doesn't change. Each rented movie costs 5.25 (17.75-12.50=5.25) and that value would be multiplied by the amount of movies she rents that month, and then added onto the original base value.

First of all to find out how much each movie cost .
17.75-12.50 = $5.25
So Jennifer paid one month $12.50 for Amazon Prime plus $5.25 = $17.75
Next month 5.25 x 7 movies = $36.75 plus 12.50 for Amazon Prime = $49.25
So to recap : one month pays $12.50 for Prime and $5.25 for one movie . Next month paid $12.50 for Prime and 7 movies totalling $36.75

Which line has a slope of 1, and which has a slope of 2?
Use a ruler to help you graph a line whose slope is 5. Label this line a.

Answers

Answer:

Line "L" has the slope of 1 and line "K" has the slope of 2.

In order to graph a line with the slope of [tex]\frac{1}{3}[/tex] think of the numerator as the "rise" (how much you move up/down on the y-intercept) and the denominator as the "run" (how much you move to the side on the x-intercept)

Step-by-step explanation:

A slope of "1" is simply [tex]\frac{1}{1}[/tex] so you rise up one and move to the right once. This clearly demonstrated on line "L".

A slope of "2" is [tex]\frac{2}{1}[/tex] so you rise up two and move to the right once, as is demonstrated on line "K".

For the 2nd question, line "A" will have a slope of [tex]\frac{1}{3}[/tex] therefore it will move up once and then to the side three times. It will look like the image attached to this answer.

Write the equation of the line in fully simplified slope intercept form

Answers

Answer:

y = -x + 8

Step-by-step explanation:

In writing an equation of a line, keep in mind that you ALWAYS need the following information in order to establish a linear equation:

1. 2 ordered pairs (x,y) on the line

2. Slope

We'll use points (1, 7) and (0, 8).

Let (x1, y1) = (1, 7)

(x2, y2) = (0, 8)

Now that we have the two ordered pairs, substitute their values into the following slope formula:

m = (y2 - y1)/(x2 - x1)

m = (8 - 7) / (0 - 1)

m = 1 / -1 = -1

Therefore, the slope of the line, m =  -1.

Next, we need to determine the y-intercept, (b).  The y-intercept is the y-coordinate of the point (0, b ) where the graph crosses the y-axis. The y-intercept is also the value of y when x = 0. Looking at the graph, we can see that it crosses the y-axis at point (0, 8). We used this point earlier to solve for the slope. The y-intercept, b = 8.

Therefore, the linear equation in slope-intercept form is: y = -x + 8.

Please mark my answers as the Brainliest if you find this helpful :)

Answer:

y = –x + 8

Step-by-step explanation:

the line is negative and decreasing by –1/1 (rise over run is the slope). a slope of 1 can be represented by writing "x". in this case the slope is –x. the b in mx+b represents the y-value that the graph starts at. in this it starts at 8.

Find the surface area of a cylinder with a base radius of 4 cm and a height of 7 cm.
Use the value 3.14 for a, and do not do any rounding.
Be sure to include the correct unit.

Answers

Answer: 276.32cm³

Step-by-step explanation:

Surface area, A, of a cylinder is given by the formula:

A = 2*pi*r*h + 2*pi*r²

r = radius

h = height

Substituting pi for 3.14 gives:

A = (2 * 3.14 * 4 * 7) + (2 * 3.14 * 4²)

A = 276.32cm³
