If someone could tell me the equation to set up the problem for me it would be great! My teacher didn’t go over how to solve it when the equation is on both sides. And if you could explain why would be totally amazing!

Answer:

4 and 5

Step-by-step explanation:

Let's make an equation to solve. Let's call "one number" x. Another number is 1 more than x, so now we have x + 1. x plus x + 1 is equal to 9... and this gives us our equation:

x + (x + 1) = 9

We can now simplify by adding like terms together:

2x + 1 = 9

Now, let's take away 1 from both sides:

2x = 8

We can finally divide both sides by 2 to isolate x:

x = 4

One of our numbers is 4. Our other number is one more than 4, and 4 + 1 = 5. So our numbers are 4 and 5.

Hopefully this was helpful! If you need more help, let me know.

Answer:

36

Step-by-step explanation:

First, just multiply 90 by 1/3. 90 is equal to 90/1 as any number divided by 1 is still equal to itself.

[tex]\frac{90}{1}*\frac{1}{3}=\frac{90*1}{1*3}=\frac{90}{3}[/tex]

Now, 90/3 is just 90 ÷ 3.

[tex]90 \div 3 = 30[/tex]

Finally, just add 6 to it.

[tex]30+6=36[/tex]

Answer:

36

Step-by-step explanation:

1/3 of 90 is 30

6 more is 30+6=36

An ellipse has the general equation

(x/a)² + (y/b)² = 1

(actually, this is an ellipse whose semimajor and -minor axes are parallel to the x- and y-axes, but one can rotate any ellipse so that it has the same configuration, and the area remains constant)

Convert to a kind of rescaled polar coordinates, using

x = a r cos(t)

y = b r sin(t)

Then the interior of such an ellipse is the set

E = {(r, t) : 0 ≤ r ≤ 1 and 0 ≤ t ≤ 2π}

The area of E is then given by the integral

[tex]\displaystyle \iint_E dA[/tex]

Compute the Jacobian determinant for this change of coordinates. The Jacobian is

[tex]J = \begin{bmatrix}x_r & x_t \\ y_r & y_t\end{bmatrix} = \begin{bmatrix}a \cos(t) & -a r \sin(t) \\ b \sin(t) & b r \cos(t)\end{bmatrix}[/tex]

Then we have Jacobian determinant

|det(J)| = |a b r cos²(t) + a b r sin²(t)| = |a b r| = |a b| r

since r ≥ 0.

The area of E is then

[tex]\displaystyle \iint_E dA = \iint_E |ab| r \, dr \, dt[/tex]

[tex]\displaystyle \iint_E dA = \int_0^{2\pi} \int_0^1 |ab| r \, dr \, dt[/tex]

[tex]\displaystyle \iint_E dA = 2\pi |ab| \int_0^1 r \, dr[/tex]

[tex]\displaystyle \iint_E dA = \boxed{\pi |ab|}[/tex]

Answer:

904.8 m²

Step-by-step explanation:

needed formulas:

surface of a circle: πr²

circumference of a circle: 2πr

The top and bottom are circles with radius 9, and surface π9² = 81π m²

The side is a rectangle of 2·π·9·7 long, so that is 126π m²

Brings the total to 81π + 81π + 126π = 288π ≈ 904.8 m²

Answer:

A = 103°; B = 77°; C = 46°

Step-by-step explanation:

A + 45° + 32° = 180°

A + 77° = 180°

A = 180° - 77°

A = 103°

A + B = 180°

103° + B = 180°

B = 180° - 103°

B = 77°

B + C + 57° = 180°

77° + 57° + C = 180°

134° + C = 180°

C = 180° - 134°

C = 46°

Answer:

Slope = - 3

Step-by-step explanation:

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

( x1, y1 ) = ( - 1, 4 )

Here,

x1 = - 1

y1 = 4

( x2, y2 ) = ( 1, - 2 )

Here,

x2 = 1

y2 = - 2

Slope = ( - 2 - 4 ) / ( 1 - ( - 1 ) )

= - 6 / ( 1 + 1

= - 6 / 2

Slope = - 3

Therefore,

The slope of the line through ( - 1, 4 ) and ( 1, - 2 )

is - 3.

Step-by-step explanation:

Answer:

So, we have the equation:

[tex]y=x^3-x^2-9x+9[/tex]

Usually, we have to do trial-by-error methods like using the Rational Root Theorem to factor cubic polynomials. However, while this may seem like a complicated cubic equation to factor, it has a simple trick to make it much easier!

We can actually factor this polynomial through Factoring by Grouping. With this method, we can factor a cubic polynomial. We split the equation into two parts, like this:

[tex]y=x^3-x^2-9x+9[/tex]

[tex]y=(x^3-x^2)+(-9x+9)[/tex]

Which can be simplified to:

[tex]y=(x^2)(x-1)+(-9)(x-1)[/tex]

We took out a factor of x^2 for the first term and a negative 9 for the second term. As we can see, we now have two terms that are the same:

(x - 1)

We can factor out the (x - 1) like this:

[tex]y=(x^2)(x-1)+(-9)(x-1)[/tex]

[tex]y=(x-1)(x^2-9)[/tex]

Now, this is not the most simplified form. See the x^2-9 term? We can use the Difference of Squares.

In general:

[tex]a^2-b^2=(a-b)(a+b)[/tex]

We have the expression:

[tex](x^2-9)=(x^2-3^2)[/tex]

[tex](x^2-3^2)=(x-3)(x+3)[/tex]

Therefore:

[tex]y=(x-1)(x^2-9)[/tex]

[tex]y=(x-1)(x-3)(x+3)[/tex]

Our fully factored form for y=x^3-x^2-9x+9 is:

[tex]y=(x-1)(x-3)(x+3)[/tex]

Step-by-step explanation:

what do we need to do ? find the 0 solutions for x ?

if that is the case, let's just do all the multiplication first :

(3/2)² × (2/3)⁴x² = x

9/4 × 16/81 x² = x

4/9 x² = x

4/9 x² - x = 0

4x² - 9x = 0

x × (4x - 9) = 0

so, one solution is obviously x = 0.

the second solution is

4x - 9 = 0

4x = 9

x = 9/4
