Answers

Answer:

1=x

Step-by-step explanation

Add 14 to both side(because it is opposite)

-6=8x-14

+14       +14

8=8x

Divide both sides by 8

8/8=8x/8

1=1x(or just 1=x)

The answer will be X=1.

Can someone show me how to do this? It’s dividing polynomials.

Find the exact value of Cosine (alpha + beta) given sin Alpha = two-fifths for Alpha in Quadrant II and Cosine Beta = one-third for Beta in Quadrant IV.

Answers

The exact value of cos (α + β) is (4√2-21) / 15.

What is angle?

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Given that,

Sin α = 2/5, and α is in second quadrant,

cos β = 1/3 , and β is in fourth quadrant

Since, α is in second quadrant, the value of cos α will be negative.

The value of cos α, by right angle triangle property,

cos α = -√21 / 5  

Since, β is in the fourth quadrant, the value of  sin β will be negative.

The value of sin β  = -  2√2 / 3

Cos (α + β) = cos α.cos β - sin α. sin β

Substitute the values here,

Cos (α + β) = (-√21 / 5)  . 1/3 - 2/5. ( -  2√2 / 3)

                   = -21/15 + 4√2/15

                   =  (4√2-21) / 15

The value of cos (α + β) is (4√2-21) / 15.

Alex was put on an improvement at work and they lowers his pay by 3% an hour before his decrease in pay he was making $14 an hour how much money is Alex making an hour afther his decrease in pay

Answers

Answer: Alex is making $ 13.58 after his decrease in pay.

Step-by-step explanation:

Given: Hourly pay for Alex before decrease in pay = $14

His salary decreased by 3%.

New hourly pay = Previous hourly pay - 3% of ( Previous hourly pay )

= $(14-0.03 (14))

= $ (14(1-0.03))

= $ (14(0.97))

=$ 13.58

Hence, Alex is making $ 13.58 after his decrease in pay.

Write the equation of a line that is
parallel to y = 0.5x + 6 and
passes through the point (6, -2).​

Answers

Answer:

[tex]y=0.5x-5[/tex]

Step-by-step explanation:

Since the equation is parallel, this means that the slope remains the same which is 0.5.

The remaining thing to do is to find b or y-intercept. To do that, the point (6,-2) and the slope of 0.5 will be used.

[tex]-2=0.5(6)+b[/tex]

When solving for b, it will equal to -5.

Therefore the new equation that is parallel is [tex]y=0.5x-5[/tex]

The equation of a line parallel to y = 0.5x + 6 and passes through the point (6, -2) is y = 0.5x + 1.

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.

We know lines parallel to each other have the same slope.

The given line can be written as y = 0.5x + 6.

Therefore, The required line also has a slope of 0.5 passing through the point (6, -2).​

- 2 = 0.5×6 + b.

- 2 = - 3 + b.

b = 1.

So, y = 0.5x + 1.

Answer:

Step-by-step explanation:

What is the difference of outputs for any two inputs that are one value apart?

If you look at the column of "x" [input], you will see that they are 1 unit apart. You can thus look at the corresponding values of "f(x)" [output] and determine their difference. Checking all of those, gives us the difference (same for all).

Life coaches, business coaches, We may or may not take them seriously, but we must know something. Most, if not all of them, be it famous ones or not-so-famous ones, agree at one valuable point: goals are crucial. Short-term as well as long-term goals are the key the achieving a more successful life.What professionals such as Tony Robbins claim is that having goals will provide you with a direction in life. The steps you take will gain value as to whether or not they take you any closer to those goals. If they dont, the best thing to do would be to evaluate how they can be changed or even left out and substituted for more efficient ones. Robbins, continually tells the story of how he wrote down every single thing he wanted to achieve in life along with the actions he would take to do so and how he did indeed achieve all of those things.When it comes to landing that beautiful and profitable a dream job, setting a long-term goal can undoubtedly direct your actions. If you choose to focus only on the short-term aspects of work and professional development, odds are that you will end up near-sighted. You will only work hard at things that can bring you immediate compensation. Those things are not naturally going to land the dream job. They will keep you alive, pay bills, and buy some food, but wont necessarily satisfy the requisites to get to the top, whatever that can mean to you.If you do choose to have a long-term goal that is dream-job related, the chances are that you will choose different paths. You will not see that ten-month course as a waste of time, since it will give you useful skills. You will spend your money more wisely, viewing it more as an investment than as a necessary evil. You will gain a new perspective of what time means and develop the sense that immediacy is overrated.There are those who call themselves realistic or, more honestly, pessimistic. They may claim that setting long-term goals is nothing but a recipe to feeling like a failure. Truth be told, it is indeed possible that you wont achieve every single thing you wish for, which is actually in most cases for us that we don't necessarily achieve our every goal. It might be our lack of willpower or that our goal was just not engineered very well. So that is a reality not only for you but for everyone else on this planet. However, not achieving something should not be a synonym for failure. It can mean some rethinking is important, some assessing needs to be done, a new plan should be concocted. Great minds goals, such as Elon Musk, are not only long term but also ambitious. And if they fail on their way, they find the means to try again, now with improved knowledge from the previously failed experience.Tony Robbins says that most people overestimate what they can do in a year, and underestimate what they can do in a decade. That is the real recipe for failure: seeing time as a factor of stress and pressure instead of an ally. By giving yourself a grand goal and a good amount of time to do it such as landing the dream job in five to ten years, you are being more realistic than you would be by either giving up altogether or trying to do it impossibly quickly. Landing a dream job takes time and effort, but as long as you set good reasonable goals, you can accomplice almost anything.
