*PLEASE ANSWER TY* What is the density of a 50-gram pyramid with rectangular base 4 cm x 8 cm and height 10 cm?

Step-by-step explanation:

→ First work out volume of pyramid using the formula    where 'l' is the length, 'w' is the width and 'h' is the height

 ⇔ ⇔   ⇔ 320 ÷ 3 = 106.666666667

→ Volume of pyramid = 106.666666667. Substitute this value into the density formula

Density = Mass ÷ Volume

Density = 50 ÷ 106.666666667

Density = 0.46875 to 1 decimal place is 0.47

D. y = 2x - 2

Step-by-step explanation:

1) First, find the slope of the given line. Place it in slope-intercept form to identify its slope easily. Isolate the y in the equation:

A line placed in slope-intercept form is represented by the formula . The , or the coefficient of the x-term, represents the slope. Thus, the slope of this line is 2.

2) Lines that are parallel share the same slope. So, the slope of the parallel line will have 2 as its slope as well.

We now have enough information to write the equation of the line in point-slope form. From there, we can convert it to slope-intercept form and find out which option is correct.

Use the point-slope formula and substitute values for , , and . Since represents the slope of the line, substitute 2 in its place. Since and represent the x and y values of a point the line intersects, substitute the x and y values of (4,6) into the formula as well. Then, with the resulting equation, isolate y like before to find which option is correct:

So, option D is correct.
