Answer:

option 2

Step-by-step explanation:

its easier because you can transfer the y to the other side and it gets easier.

2x = -10y

x = 2/-10 y

x = -5y

Answer:

2x + y = -10

Step-by-step explanation:

2x + y = -10

y = -2x - 10

This can then be substituted for y, for the first equation.

I assume you should set up an equation in y=mx+b form (but you use C(t) instead of y). m is your rate, b is your flat fee, and x is t.

Find the volume of a pyramid with a square base, where the side length of the base is

valina [46]

Answer:

Volume = 1114.1 $in^3$

Step-by-step explanation:

Recall that the formula for the volume of a pyramid is given by:

$Volume=\frac{1}{3} \,B\,*\,H$

where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).

Then the square base of the pyramid has an area given by: $(12.8\,\,in)^2=163.84\,\,in^2$

Finally,we can now write the volume of the pyramid as:

$Volume=\frac{1}{3} \,B\,*\,H\\Volume=\frac{1}{3} \,(163.84)\,*\,20.4\,\,in^3\\Volume=1114.112\,\,in^3$

Rounding the answer to a tenth of a cubic inch, we get:

Volume = 1114.1 $in^3$

The function h(x) = g(x + 2) - 1, complete the table for h(x).

Dafna1 [17]

Answer:

x g(x + 2)-1 h(x)

-2 g(-2+2)-1 -1

-1 g(-1+2)-1 0

0 g(0+2)-1 1

1 g(1+2)-1 2

2 g(2+2)-1 3

Part A: 3

Part B: -1

Step-by-step explanation:

When you have questions like these all you have to do is plug in and solve.

For example I will do h(2) & h(-2) for reference.

h(2):

$(2+2)-1\\4-1\\3$

h(-2):

$(-2+2)-1\\0-1\\-1$
