The slope between the points (-1,-5) and (r, -9) is 2. What is the value of r?

Mathematics

Gnom [1K]2 years ago
4 0

Answer:

r = 2

Step-by-step explanation:

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

(-1, -5)

(r, -9)

-5 - (-9) / -1 - r = 2

4 / -1 - r = 2

r = -2

-1 - (-3) = 2

4 / 2 = 2

Please let me know if I've gotten anything wrong!

How do I find it out
Paraphin [41]
The two equations are in the slope-intercept form, y = mx + b.

m is the slope and it is the rate of change.
b is the constant, and it is the initial value.

Eq. A: y = 3x + 4  ---> rate of change = m = 3; initial value = b = 4
Eq. B: y = 5x + 2  ---> rate of change = m = 5; initial value = b = 2

Now you can see which statement is true.

A. False
B. True
C. False
D. False

Calculate the total surface area of a rectangular box 10cm long, 8cm wide and 6cm tall.<br>​
kicyunya [14]

Answer:

The answer is

<h2>376 cm²</h2>

Step-by-step explanation:

Since the rectangular box is a cuboid,

Total surface area of a cuboid is given by

<h3>2( lw + wh + lh)</h3>

Where

l is the length

w is the width

h is the height

From the question

l = 10 cm

w = 8cm

h = 6cm

Substitute the values into the above formula

That's

Total surface area of the rectangular box is

2 [ (10)(8) + (8)(6) + (10)(6) ]

2 [ 80 + 48 + 60 ]

2( 188)

We have the final answer as

<h3>Total surface area = 376 cm²</h3>

Hope this helps you
