Answer:

D) 3

Step-by-step explanation:

Given: The line passes through the points (1, 7) and (-4, -8)

Here we have to use formula to find the slope.

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

Here x1 = 1, y1 = 7, x2 = -4 and y2 = -8

Now plug in these values in the above formula, we get

slope = (-8 - 7) / (-4 - 1)

= -15/-5

slope (m) = 3

Therefore, the slope of the line is 3.

Answer: D) 3

Hope you will understand the concept.

Thank you.

Answer:

D. 3

Step-by-step explanation:

To find the slope of a line, we can use the equation y2-y1/x2-x1=m or slope.

All we can do now is insert the values of the points into the equation.

-8-7/-4-1=m

-15/-5=m

3=m

Thus, the slope is 3.

Hope this helps!

Mozart's Music Store rents trombones for $34 a month. Bach's Music Store rents trombones for $30 per month plus a yearly fee of
jeka94

Answer:

Step-by-step explanation:

Let M(x) be the cost of renting from Mozart's Music Store for x years, and B(x) be the cost of renting from Bach's Music Store for x years.

From the problem statement, we can come up with the following equations:

M(x) = 34(12x)

B(x) = 30(12x) + 48x

Plugging in x = 9 for each equation, we can get the answer:

M(9) = 34(12 * 9)

M(9) = 34(108)

M(9) = 3672

B(9) = 30(12 * 9) + 48(9)

B(9) = 30(108) + 432

B(9) = 3240 + 432

B(9) = 3672

From this, we can see that the value is equal for both stores.

  f(g(x)) = 1, 4, 5, 3, 2

  g(f(x)) = 5, 2, 4, 1, 3

Step-by-step explanation:

To find f(g(x)), locate g(x) in the third column (labeled g(x)). Use that value as x in the first column, then read f(x) from the second column.

Example: f(g(1)) = f(2) = 1

__

To find g(f(x)), locate f(x) in the second column (labeled f(x)). Use that value as x in the first column, and read the corresponding g(x) from the third column.

Example: g(f(1)) = g(2) = 5

STatiana [176]

A rectangular school banner has a length of 44 inches, a perimeter of 156 inches, and an area of 1,496 square inches. the cheerleaders make signs similar to the banner. the length of a sign is 11 inches. First solve the width of the rectangle:

1496 sq in/ 44 = 34 in

So the sign has also a width of 34 in and a length of 11 so the area is 34*11 =374 sq in

<span>The perimeter is (34*2) +(11*2) =90 in</span>

xxMikexx [17]
If we let
x as the distance traveled by the boat
y as the distance between the boat and the lighthouse.

Then, we have:
tan 18°33' = 200 / (x + y)
and
tan 51°33' = 200 / y

Solving for y in the second equation:
y = 200 / tan 51°33'

Rearranging the first equation and substituting y
x = 200 / tan 18°33' - 200 / tan 55°33'
x = 458.81 ft

Therefore, the boat traveled 458.81 ft before it stopped.
