Answer: x = 30

Explanation:

This equation is almost solved, it is on the last part of the equation.

First thing you must always do is write the equation as you see it, making sure you don’t miss any plus or minus signs:

-1/5x = 6

Next, you must do the math. All that you must do is divide the the side that doesn’t have x with the side that does:

6 ÷ -1/5x

Change the fraction into decimal ( that is optional, but it makes that math easier):

6 ÷ 0.2x = 30x

Your answer is 30x

Hope this helps! :)

Vivek worked 35 hours and earned $385. At this rate, how many hours would it take him to earn $143?

earnstyle [38]

35 divided by 385 is 11. This means Vivek will earn $143 in 11 hours.
Comment if I am wrong.

Y=-2x²-8x-5 domain and range

Jobisdone [24]

Answer:

Domain: All real numbers

Range: y≤3

Step-by-step explanation:

The given function is

$y = - 2 {x}^{2} - 8x - 5$

This is a polynomial function.

The domain is set of all values of x, that makes this function defined.

Since polynomial functions are defined everywhere, the domain is all real numbers.

To find the range we put the function in vertex form:

$y = - 2( {x}^{2} + 4x) - 5$

$y = - 2( {x}^{2} + 4x + 4) - 5 + - 4 \times - 2$

$y = - 2( {x} + 2)^{2} - 5 + 8$

$y = - 2( {x} + 2)^{2} + 3$

The maximum value is 3

The function turns downward, hence the range is:

$y \leqslant 3$
