Explanation on How to answer what is the density of an object that has a mass of 73,430 and the volume of 7 m3
scZoUnD [109]

Answer:

Density = 10,490 g/m³

Finding the slope passing through the points
marissa [1.9K]

<u>Question 1</u>

Since the x-coordinates are the same, the line is vertical. Therefore, the slope is undefined.

<u>Question 2</u>

Since the y-coordinates are the same, the line is horizontal. Therefore, the slope is zero.

Express V in terms of T
Lorico [155]

Answer:

v = \frac{4t-1}{3}

Step-by-step explanation:

Given

t = \frac{3v+1}{4} ( multiply both sides by 4 to clear the fraction )

4t = 3v + 1 ( subtract 1 from both sides )

4t - 1 = 3v ( divide both sides by 3 )

\frac{4t-1}{3} = v

Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2

y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3

equation
y = -1/2x - 3

answer is B.
y = -1/2x - 3
