Answer:

(1, 4)

Step-by-step explanation:

5x-2y=-3 -2x-y=-6  =>

5x-2y=-3

-2x-y=-6   Multiply all three terms by -2:  4x + 2y = 12

Then we have:

5x-2y=-3

4x + 2y = 12

---------------------

 9x = 9 and so x = 1.  Then, using -2x - y = -6,  and substituting 1 for x:

-2(1) - y = -6, or

2 + y = 6, or

y = 4

Then the solution is (1, 4)

Find the inverse of g(x)=1/3x - 7 and then find its domain and range if you can show steps that would be gladly appreciated than
Schach [20]

Answer:

g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.

Step-by-step explanation:

Let y = 1/3 x - 7

1/3 x = y + 7

Multiply both sides by 3:

x = 3(y + 7)

So the inverse of g(x) = g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.

Suppose the temperature outside is dropping 3 degrees each hour how much will the temperature drop in 8 hours
vovikov84 [41]
It would drop by 24 degrees

3 x 8 = 24

For each hour another long way is simple just do

3 x 4 = 12 now just double it
12 + 12 = 24

Part D ? Question Suppose the cylindrical water tank has a radius of 12 feet. Use this information and the equation modeling the
Wittaler [7]

The volume of the cylindrical water tank that has a length of 20 feet and a radius of 12 feet is about <u>9,048</u> cubic feet.

The correct option is option <em>d</em>;

d. 9,048

<h3>What is the volume of a solid?</h3>

The volume of a solid indicates the amount of space the solid takes at a location.

The formula for finding the volume of the cylindrical tank is presented as follows;

<em>V</em> = π·r²·L

Where;

r = The radius of the tank

L = The length of the tank

From a similar question on the website, we have;

The length of the tank, <em>L</em> = 20 feet

Therefore;

The volume of the tank, <em>V</em> = π × 12² × 20 ≈ 9048

  • The volume of the water tank is about <u>9,048</u> cubic feet

In order to determine the slant height of several pyramids, Marjorie used the surface area formula, s= 1/2 pl+b for the slant he
m_a_m_a [10]

Answer:

l=\dfrac{2(S-b)}{P}

Step-by-step explanation:

The surface area formula for pyramids is given by :

S=\dfrac{1}{2}Pl+b ...(1)

We need to arrange the formula for l.

Take b to LHS,

S-b=\dfrac{1}{2}Pl\\\\2(S-b)=Pl\ [\text{cross-multiplying}]\\\\l=\dfrac{2(S-b)}{P}

So, the expression is \dfrac{2(S-b)}{P} for the slant height.
