What is the solution to -(4x-3) = -7(9+x) ???

Answers

Answer 1

Answer:

The solution is -22

Step-by-step explanation:

The solution of an equation is the value of the variable of the equation

-(4x - 3) = -7(9 + x)

→ Simplify each side

∵ -(4x) - -(3) = -7(9) + -7(x)

∴ (-4x) - (-3) = -63 + (-7x)

→ Remember (-)(-) = (+) and (-)(+) = (-)

-4x + 3 = -63 - 7x

→ Add 7x to both sides

∴ -4x + 7x + 3 = -63 - 7x + 7x

3x + 3 = -63

→ Subtract 3 from both sides

∵ 3x + 3 - 3 = -63 - 3

3x = -66

→ Divide both sides by 3

x = -22

The solution is -22

Use the​ slope-intercept form to graph the equation y=-8/3x+3

Answers

Answer:

See below :)

Step-by-step explanation:

The easiest way to graph this is to find the x-intercept and y-intercept,

y-intercept:

The y-intercept is extremely easy to find as it's just the "b" in "y = mx + b"

If there is no b, it's (0,0). If there is a b, its (0,b)

This is because the y-intercept is where the lines hits the y-axis so we know x must be 0. We can plug in x as 0 to find y:

y = m(0) + b

y = b

In this case, the y-intercept is (0,3) because the b in y = -8/3x + 3

x-intercept:

The x-intercept requires a little more work. It's the same as the y-intercept. The x-intercept is where the lines hits the x-axis so we know y must be 0. The x-intercept is (x,0)

We can use this to plug in y as 0:

0 = mx + b

mx = -b

Now we use this to find the the x-intercept:

0 = -8/3x + 3

8/3x = 3

Divide both sides by 8/3:

x = 3 * 3/8

x = 9/8

In this case, the x-intercept is (9/8,0)

Now we can use these points and connect a line to them and then the lines keeps going forever. Look at the picture I uploaded :)

At a college bookstore, Tanisha bought a Math Textbook and a Novel for $54. If the price of the Math Textbook is $8 more than 3 times the price of the Novel, then how much is the price of each book?

Answers

Answer: Price of Math Textbook= $42.5,  Price of the Novel= $11.5

Step-by-step explanation:

Let x = price of the Novel.

Price of Math Textbook = 8+3x

As per given , we have

Price of Math Textbook + Price of the Novel = $54

⇒ 8+3x+x = 54

⇒ 8+4x=54

⇒ 4x = 46     [subtract 8 from both sides]

⇒ x = 11.5

Price of Math Textbook = 8+3(11.5) = 8+34.5= $42.5

Hence, Price of Math Textbook= $42.5,  Price of the Novel= $11.5

A peach pie is made with 13 peaches, which are evenly distributed throughout the pie. If Joe ate one slice of pie that contained exactly 5 peaches, what wqs the angle measure of the slice to the nearest tenth of a degree?

Answers

Answer:

138.5°

Step-by-step explanation:

A peach pie is in the form of a circle. The sum of angles in a pie is equal to 360°.

Since there are 13 peaches evenly distributed, therefore each peach occupies 360/13 degrees.

Joe ate one slice of pie that contained exactly 5 peaches, hence:

Angle measure of slice = (number of peaches in the slice / total number of peaches) * 360°

Angle measure of slice = (5 / 13) * 360°

Angle measure of slice = 138.5°

Mose decides to launch a rocket out of the barn at Schrute farms. The equation below represents the height (in meters), of the rocket getting launched above the ground, t seconds after the rocket is launched. h(t) = -.4 (t - 2)^2 + 5 How high above the ground is the rocket before it is launched?

Answers

Height at an instance of time is given by :

h(t) = -4( t - 2 )² + 5     .....1

Differentiating above equation with respect to t .

[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]

Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .

8( t - 2 ) = 0

t = 2

Putting value of t = 2 in given equation, we get :

h( 2 ) = -4( 2 - 2 )² + 5

h( 2 ) = 5 m

Therefore, maximum height rocket can reach is 5 m.

What expression has a value of 15 when x = 15

Answers

Answer:

I suppose 1x is a possible expression. The question confuses me because  I feel like there are supposed to be other options

Step-by-step explanation:

The expression having a value of 15 when x is equal to 15 is y = x.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

We know an equation y = x which is called an identity equation.

It is called the identity function as the values of x and y are identical.

Therefore, an expression having a value of 15 when x is equal to 15 must be an identity function which is f(x) = x or y = x.
