Find the solution set of the inequality:<br> -3x + 8 < 15

telo118 [61]

Hello from MrBillDoesMath!

Answer:

x > -7/3

Discussion:

-3x + 8 < 15 => add 3x to both sides

(-3x + 3x) + 8 < 15 + 3x => (-3x + 3x) = 0

8 < 15 + 3x => subtract 15 from both sides

8-15 < 3x => 8 - 15 = -7

-7 < 3x => divide both sides by 3

-7/3 < x

Thank You,

MrB

17. Consider the function f(x, y, z) = xy ln(yz).

Lelu [443]

We can expand

$f(x,y,z) = xy\ln(yz) = xy \ln(y) + xy\ln(z)$

Then using the product and chain rules,

$\dfrac{\partial f}{\partial x} = y\ln(y) + y\ln(z) + \boxed{y\ln(yz)}$

$\dfrac{\partial f}{\partial y} = x\ln(y) + \dfrac{xy}y + x\ln(z) = \boxed{x\ln(yz) + x}$

$\dfrac{\partial f}{\partial z} = \boxed{\dfrac{xy}z}$

Rewrite the expression using distributive property : 30x + 6

Anit [1.1K]

Answer:

This cannot be done, but it can be factored as: 6(5x + 1)

Step-by-step explanation:

This expression cannot be distributed any further.

The distributive property is used when multiplying polynomials (multiplying one or more terms by two or more terms). In which case, each term in multiplied by each of the terms in the bracket, for example: .

5(x + 2) = 5x + 10

We can factor this expression however to go the opposite direction:

30x + 6

Since 30 and 6 are both divisible by 6, we can factor it out of each term.

Divide 30x by 6 and divide 6 by 6.

6(5x + 1)

Part of the arena is being turned into a public darkroom. The floor needs covering in rubber tiles before work can begin on the

vladimir2022 [97]

The number of tiles used is 300 tiles.

According to the statement

We have given that:

The tiles are 20 cm by 30 cm. And the dark room floor is 6 meters by 3 meters.

And we have to find that the number of tiles used to prepare the dark room.

So, For this purpose we have to find the area of the room floor.

The area of the floor is 6 *3.

The area of the floor is 18 meter per square.

The area of the tile is 0.2*0.3

The area of the tile is 0.06 meter per square.

Now,

The number of tiles used is 18/0.06

The number of tiles used is 300.

So, The number of tiles used is 300 tiles.
