Through (-3, 2) parallel to y = -2x-1

Mathematics

Answer:

y = - 2x - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x - 1 ← is in slope- intercept form

with slope m = - 2

Parallel lines have equal slopes , then

y = - 2x + c ← is the partial equation

To find c substitute (- 3, 2 ) into the partial equation

2 = 6 + c ⇒ c = 2 - 6 = - 4

y = - 2x - 4 ← equation of parallel line

What’s the volume of the pyramid

ValentinkaMS [17]

Answer:

The volume of the given pyramid is 300 cm³

Step-by-step explanation:

The volume of a pyramid, $V_{pyramid}$ , is given as follows;

$V_{pyramid} = \dfrac{1}{3} \times Base \ area \times Height$

The height of the pyramid = 12 cm

The side length of the square base of the pyramid = 5 cm

The base area of the pyramid polyhedron with square base = 5 cm × 5 cm = 25 cm²

Therefore, by substitution, we have;

$V_{pyramid} = \dfrac{1}{3} \times 25 \ cm^2 \times 12 \ cm = 300 \ cm^3$

The volume of the given pyramid, V = 300 cm³.
