How do you write the equation in slope intercept form given (3,-9),(0,3

Mathematics

Neko [114]3 years ago

Answer:

<h2>        y = - 4x + 3</h2>

Step-by-step explanation:

Slope:

m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-9)}{0-3}=\dfrac{12}{-3}=-4

Point-slope frorm:

y-y_o=m(x-x_o)

m = -4 ;    point (0, 3)   ⇒   x₀=0,  y₀=3

y - 3 = - 4(x - 0)

y - 3 = - 4x            

y = - 4x + 3     ←   slope intercept form

Answer the question to become brainliest
marishachu [46]

Answer:

2406.17 cm³

Step-by-step explanation:

The following data were obtained from the question:

Height (h) = 24.4 cm

Base length (L) = 17.2 cm

Volume (V) =?

Next, we shall determine the base area of the pyramid. This can be obtained as follow:

Base length (L) = 17.2 cm

Base area (B) =.?

B = L × L

B = 17.2 × 17.2

B = 295.84 cm²

Finally, we shall determine the volume of the pyramid. This can be obtained as follow:

Height (h) = 24.4 cm

Base area (B) = 295.84 cm²

Volume (V) =?

V = ⅓Bh

V = ⅓ × 295.84 × 24.4

V = 2406.17 cm³

Thus, we volume of the pyramid is 2406.17 cm³

Please help and solve for x! (: thank you in advance.

First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57 
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48

What is the volume of this?
yawa3891 [41]
Hello there.

Answer: Split the shape into two
Calculate both shapes separately
10 x 10 x 10 = 1000
20 x 20 x 20 = 8000.
Add together both values:
8000 + 1000 = 9000in³

Hope Thus Helps You!
