Find The Value Of 4w +1 Given That -3w-7=2.Simplify Your Answer As Much As Possible.

Answers

Answer 1

Answer:

-11

Step-by-step explanation:

-3w - 7 = 2

-3w (- 7 + 7) = 2 + 7

-3w = 9

-3w/-3 = 9/-3

w = -3

4w + 1

4(-3) + 1

-12 + 1

-11

Answer 2

Answer:

4w + 1 = -11

Step-by-step explanation:

Solving -3w - 7 = 2

By adding 7 to both sides of the equation  we get -3w = 9

to get to w = ... we need to divide both sides with -3, which gives us

w = -3. You can check this answer by putting it back into the original equation ( -3 * -3 - 7 does equal 2,  which means our solution for w is correct.

Now all we have to do is put our solution for w into the remaining equation:

4 * -3 + 1 = -12 + 1 = -11

Tony is going to watch a movie in his collection. He has 5 action movies, 4 comedies, and 3 dramas.
He will randomly select one movie. What is the probability that the movie he selects is not a drama?

Answers

probability 9/12 or 3/4

Answer:

9/12 (75%)

Step-by-step explanation:

There's a total of 12 movies (5+4+3).

Since there are 5 action, there's a 5/12 probability that he selects action.

4 comedies, so 4/12 probability that he selects comedies.

3 dramas, so 3/12 probability that he selects drama.

4+5 = 9 so there's a 9/12 or 75% probability that he won't select drama.

Solve the inequalities;


1. |4x + 5| + 2 ≥ 10


2. |2x + 3| + 6 > 0

Answers

Answer:

Number two: x > -9/2, x < 3/2

Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4

Step-by-step explanation:

Number one:

|4x+5| > 10-2

|4x+5| > 8

4x+5 > 8

-(4x+5) > 8

x > 3/4

x < -13/4

x > 3/4, x < -13/4

(all of these signs are greater than or equal to and less than or equal to)

Number two:

|2x+3| > -6

2x+3 > -6

-(2x+3) > -6

x > -9/2

x < 3/2

x> -9/2, x < 3/2

(all of these signs are correct and not greater than or equal to or less than or equal to)

Can someone help me.....​

Answers

Answer:

The square root of 2 is between 1 and 2, so radical 2 is about 1.4.

Step-by-step explanation:

You can plot a 1 on the very left and a 2 on the very right of the number line.

Since there is no formal square root of 2, you have to estimate.

It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.

It also has to be greater than 1 because 1 * 1 = 1 and that's too low.

I would estimate it to be right before the middle line.

which is parallel to the line y = -5/8x+6

Answers

Answer:

The answer lies in the gradient.

Step-by-step explanation:

The gradient in this equation is -5/8. If any line has the same gradient as the equation above they are parallel because they have the same slant or tilt. Gradient determines if a line is parallel between linear line graphs. If the gradient between two linear line graphs are equal that means that they are parallel.

First identify what is the gradient of a line. The gradient is usually the number that is multiplied with x. In this case (-5/8x), -5/8 is the gradient.

Hope this help.

Step-by-step explanation:

let the length be X and breadth be 2x

p=2(l+b)

24=2(X+2x)

24=2x+4x

From 1985 through 1995, the yearly gross farrm revenue (in millions) in the United States can be modeled by the function R(t)=-t^2+7t+159 and the yearly farm cost (in millions) in the United States can be modeled by the function c(t)=t^2+131 where t is the number of years since 1985. Write a new function, P(t), that models the yearly profit after 1985

Answers

The profit function is simply the difference between the revenue function and the cost function. The profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

Given that:

[tex]R(t) = t^2 + 7t + 159[/tex]

[tex]c(t) = t^2 + 131[/tex]

The profit function P(t) is calculated as follows:

[tex]P(t) = R(t) - c(t)[/tex]

So, we have:

[tex]P(t) = t^2 + 7t + 159 - (t^2 + 131)[/tex]

Open brackets

[tex]P(t) = t^2 + 7t + 159 - t^2 - 131[/tex]

Collect like terms

[tex]P(t) = t^2- t^2 + 7t + 159 - 131[/tex]

[tex]P(t) = 7t + 28[/tex]

Hence, the profit function that models the yearly profit after 1985 is [tex]P(t) = 7t + 28[/tex]

One angle of a right triangle is 2 less than 3 times the size of the other acute angle. What is the measure of each
angle?

Answers

Explanation:

Right-angled triangles have one of their angles to be 90°.

Angles in a triangle is 180°

=>The other two angles will sum up to 90°

Let x represent the other acute angle

2 less than 3 times the size of the other acute angle.

3(x)-2=one angle.

Equating both angles to 90°

=> other acute angle + one angle =90°

=> x+3x-2=90°

=>4x-2=90°

=>4x=90-2

=>4x=88

Divide both sides by 4

x=22°

Other acute angle=22°

One angle= 3(22)-2

=>66-2

=>64°

Proof= 22+64+2+90=180°


S(-4, -6) and T(-7, -3); Find R.

Answers

Answer:

(13,-6)

Step-by-step explanation:

The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.

First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.

Then do the same thing with the y coordinate. And you get -6.

Your endpoint is (13,-6)

-10x + 2y = 4

add 10x to both sides (we do that because it cancels the negative 10x out)

2y = 4 + 10x

divide everything by two (because we need to get y alone on one side)

y = 2 + 5x

flip the 5x and 2 (because that is the form of y intercept form)

y = 5x + 2

Now, the blue line is real GDP per capita it didn't actually have a plunge at any point being a fast growing economy up to the end of the `80s. Japan basically, stagnated in terms of real per capita GDP with a few Wiggles. That's the infamous last decade in Japan One thing that I've been saying lately is that in light of what we've been going through- in all the world including Japan these last few months- Japan's lost decade is starting to look pretty good. There was no mass unemployment there was no extreme plunge in the economy, But it was certainly frustrating. -They slid into a recession that basically, never ended what was worse it was unresponsive -They slipped into a into an infection that was resistant to the usual antibioticsThat was a deeply alarming thing: Japan in his last decade was not a terrible place to live; It was not mass unemployment, It was not blood in the streets, but it was intense prolonged frustration of the inability to get that economy moving again. I wasn't alone obviously, in thinking about the Japanese example; I at least said Japan basically, looks a lot like us. If they can be caught in the trap like this for an extended period Why, can't it happen to to other countries? So there were a number of people worrying about that. It was on people's mind as a possibility, And the thing is it the it came true, we got into a situation of overextension excessive leverage and the mother of all housing bubbles. When all of that burst we were plunged into a recession- and the Fed had thought about how to deal with something like a Japanese trap- Their first rule was cut interest rates early and often basically, aggressive, initial monetary policy response which they did. But it wasn't enough and went all the way to zero ,and the economy is still shrinking found themselves in the liquidity trap.Now, this is where we begin the Alice Through the Looking class discussion a situation where short term interest rates are zero. Normally, monetary policy is made by cutting a target interest rate where you've gone all the way to the end of that that was named the liquidity trap. Meaning that you can normally increase the quantity of money. That means that people have more liquidity than they need, they lend it out, you get sort of chain reaction through the credit markets, that helps to expand the economy, But if interest rates are zero, people are saturated, they have as much liquidity as they want. This was advanced not in those words, but it's advanced as a central theme in Keynes's General Theory. It was somewhat formalized by john Hicks, but it's sort of vanished from consideration In economics you can actually sort of see why, But when something like it arrived in Japan and now, for all of us today a lot of people found it hard to believe that there was a widespread belief, that well look if the central bank prints a bunch of money that has to have an expansionary effect on the economy. In fact, it has to be inflationary I mean, we just know that printing money is inflationary. We have this, standard way that we do short term macroeconomics, the is model, but everybody who does that knows that it's ad hoc, It's not really grounded in micro foundations all these things that economists say, And presumably if you thought about it really carefully, and dotted all your I's and crossed all your T's, you would come to the conclusion that of course expanding the money supply is effective no matter what. And to my shock it actually gave me the opposite answer, "Liquidity trap can be real it really can be true that that printing money has no effect." On the reason once you think about it is pretty clear. Really, once you for whatever reason have gotten a situation where short term interest rates are zero Well, then you go and do conventional monetary policy.
