What is the slope of the line parallel to 3x + y = 12?

Doss [256]

Answer:

slope = -3

Step-by-step explanation:

1) Rearrange eqn into slope intercept form

slope intercept form: y = mx + b

where...

m = the slope

b = the y-intercept (where the line crosses the y axis)

3x + y = 12

y = -3x+12

2) Know parallel rule. A line that runs parallel has the same slope but a different y-intercept

So the slope is: -3

A square pyramid has a base length of 4 inches. The height of each triangular face is 12 inches. What is the surface area of the

Wittaler [7]

Answer:

The surface area of the given pyramid is 112 $inches^{2}$ .

Step-by-step explanation:

Base length of the pyramid = 4 inches

Area of the base = $length^{2}$

= $4^{2}$

= 16

Area of its base = 16 $inches^{2}$

Area of one of its triangular surface = $\frac{1}{2}$ x base x height

= $\frac{1}{2}$ x 4 x 12

= 2 x 12

= 24 $inches^{2}$

Area of all its four triangular surfaces = 4 x 24

= 96 $inches^{2}$

surface area of the pyramid = sum of areas of all its surfaces

= 16 + 96

= 112 $inches^{2}$

The surface area of the given pyramid is 112 $inches^{2}$ .
