Answer:
Volume of the rock=
Step-by-step explanation:
Volume of triangular pyramid = 
Where B is the area of base
H is the height of pyramid
Length if base of base triangle = 8.5 inches
Height of base = 4 inches
Area of base triangle = 
Height of pyramid = 12 inches
Volume of triangular pyramid = 
So, option D is true
Volume of the rock=
Answer:
slope is 2
Step-by-step explanation:
first add -14x like...
-14x+7y=-9
+14x +14x
7y=14x-9
divide 7 by the who equation
7y=14x-9
/7
y=2x-9/7
Answer:
y = -1/4x + 1
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
The y-intercept of the line is 1, so in slope-intercept form, b will be 1.
Now, the line also intersects the y-axis at (4, 0). We can plug these two points into slope formula to find the slope: (0-1)/(4-0) = -1/4.
Therefore, the equation of the line is y=-1/4x + 1
Answer:
B

Answer:
y = -3/7x + 5
Step-by-step explanation:
y2 - y1 / x2 - x1
2 - 8 / 7 - (-7)
-6/14
= -3/7
y = -3/7x + b
2 = -3/7(7) + b
2 = -3 + b
5 = b
