(8, 1) and (-1, 10)<br> Slope
gizmo_the_mogwai [7]

Answer:

<h2>The answer is 1</h2>

Step-by-step explanation:

The slope of the line between two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}

where

(x1 , y1) and (x2 , y2) are the points

From the question is points are

(8, 1) and (-1, 10)

Substitute the values into the above formula and solve for the slope

That's

m =  \frac{10 - 1}{8 + 1}  \\  =  \frac{9}{9}   = 1

We have the final answer as

<h3>1 </h3>

Hope this helps you

If Ryan uses only 3/8 cup syrup out of the giant bottle each time he eats pancakes, how many times will he be able to eat pancak
elena55 [62]

Answer:

128 times

Step-by-step explanation:

Total cups = volume per meal × no. of meals

C = V × n

Divide each side by V

n = C/V = 48/(⅜)

Invert the fraction and multiply

n = 48 × ⁸/₃

Cancel 3s

n = 16 × 8  

Multiply

n = 128

Ryan can eat pancakes 128 times from his giant bottle without running out of syrup.

What is the measure of ∠x?
Archy [21]

Answer:

114 degrees

Step-by-step explanation:

Hi there.

Line segment LN is a straight line, meaning that it contains a straight angle (an angle measuring 180 degrees).

We know that if this is a straight angle, that x+66=180.

Therefore, m∠x = 114 degrees.

Hope this helps! :^)
