What is the slope of the line that passes through the points (1, -6) and (-8, 9) ?Write your answer in simplest form.
Dmitry [639]

Answer:

5/-3

Step-by-step explanation:

The slope formula is rise/run.

If you graph this, the two points make a line that slopes downwards. The higher point is in the negative axis, which means that the run will be negative.

you rise up 15 points from the first point (1,-6) to get to the same level as the second point. (-8,9). This is your rise.

You go over to the other point, this is your run. The run is -9.

15/-9

we can simplify  this fraction.

5/-3 is your final answer.

a right triangle has a height of 20 centimeters and a base of 10 centimeters.what is the area of the triangle?
viktelen [127]

Answer:

<u><em>The </em></u><u><em>area of the right triangle</em></u><u><em> is </em></u><u><em>100 centimeters squared.</em></u>

Step-by-step explanation:

<u><em>The </em></u><u><em>formula for the area of a right triangle is:</em></u>

Area = \frac{a*b}{2}

<u><em>Area = (a*b) / 2</em></u>

<u><em>The height of a triangle is represented by a. The base is represented by b.</em></u>

<u><em>Knowing this, we can use what they give us for the values, by </em></u><u><em>plugging them into the formula</em></u><u><em>.</em></u>

<u><em>a is 20 cenimeters</em></u>

<u><em>b is 10 centimeters</em></u>

<u><em>Therefore :</em></u>

Area = \frac{200}{2}

Area = 100

<u><em>So, the </em></u><u><em>area of the right triangle</em></u><u><em> is</em></u><u><em> 100 centimeters squared.</em></u>

BRAINLIEST ASAP! PLEASE. HELP ME :) I need help with part 2 of the question.
tino4ka555 [31]

Part 2:

-4a + 2 + 11a = 5a + 3 + 2a

~Combine like terms

7a + 2 = 7a + 3

~Subtract 2 to both sides

7a = 7a - 1

~Subtract 7a to both sides

0 = 1

Therefore, there are no solutions.

Best of Luck!
