One number is one more than another. Their sum is nine. Find both numbers.
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.

I need help ASAP please “f(x)= ?”
Step-by-step explanation:
just think - what does it mean to translate (shift) a graph upward by 5 units ?
does the graph change in its content ? no. all the functional result value (= y values or coordinates) are still calculated as before, BUT before marking them on the chart the y values are moved up by 5 units. that means they are increased by 5 (that is the only way to move something "up" on a coordinate grid).
so, in other words, f(x) is nothing else but h(x), but it increases the results of h(x) consistently by 5.
h(x) = 2x² + 4
f(x) = h(x) + 5 = 2x² + 4 + 5 = 2x² + 9

Answer:
m ∠x = 81° and m ∠y = 109°
Step-by-step explanation:
m ∠R = 1/2 (arc REG) m ∠G = 1/2(arc REF)
89° = 1/2 (arc REG) 81 = 1/2(arc REF)
178° = arc REG 162° = arc REF
m ∠x = 1/2 arc REF
m ∠x = 1/2( 162°)
m ∠x = 81° or m ∠G = m ∠x because these to angles intersect the same arc, therefore they are equal.
Now the polygon interior angles = 360° and you know the measure of three of the four angles, solve for the missing angle .
m ∠R + m ∠x + m ∠y + m ∠G = 360°
89° + 81° + m ∠y + 89° = 360°
(89 + 81 + 81) + m ∠y = 360°
251° + m ∠y = 360°
m ∠y = 109°
How to calculate the area of an ellipse by using integration?
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]

I need help with surface area
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:
Option D is your answer.
Step-by-step explanation:
Remember that the x-values are the x coordinates and the y-values are the y coordinates in an ordered pair. Ordered pairs are written like this (x,y).
So for line r, you got (-6,4), (-3,0), and (0,-4).
But you only need two of these pairs to determine slope. Let's do that real quick, by using this formula. (Sorry if it's small)⤵⤵⤵
[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } [/tex]
We'll use (-6,4) and ( -3,0).
0 - 4 = -4
-3 - (-6) = -3 + 6 = 3
So slope of line r is -4/3.
Now we'll do the same for line s:
Ordered pairs = (-5,-4), (5,0), and (20,6)
We'll use (-5,-4) and (5,0).
0 - (-4) = 0 + 4 = 4
5 - (-5) = 10
So slope of line s is 4/10 or 2/5.
Now we got to find the option choice that has these as the slopes.
We'll turn each into slope-intercept form.
A)
- Subtract 4x on both sides to get
3y = -4x - 12, then divide 3 on both sides to get y = -4/3 x - 4.
- Subtract 2x on both sides to get
-5y = -2x + 10, then divide -5 on both sides to get y = 2/5 x - 2.
B)
- Add 4x on both sides to get
3y = 4x + 12, the divide 3 on both sides to get y = 4/3 x + 4.
- Subtract 2x on both sides to get
-5y = -2x - 10, divide -5 on both sides to get y = 2/5 x + 2.
C)
- Subtract 4x on both sides to get
-3y = -4x - 12, then divide -3 on both sides to get y = 4/3 x + 4.
- Add 2x on both sides to get
-5y = 2x + 10, then divide -5 on both sides to get y = -2/5 x -2.
D)
- Add 4x on both sides to get
-3y = 4x - 12, then divide -3 on both sides to get y = -4/3 x + 4.
- Add 2x on both sides to get
5y = 2x + 10, then divide 5 on both sides to get y = 2/5 x + 2.
After all that writing we can tell that D is our answer, because both -4/3 and 2/5 appear as slopes.
Sorry this may seem like a lot, but the process really isn't that hard. Hope this helps :)

[tex] \frac{4.8}{1 \frac{7}{9} } = (1.2b) \div 6 \frac{2}{3} [/tex]
[tex] \frac{ \frac{48}{10} }{ \frac{16}{9} } = \frac{12b}{10} \div \frac{20}{3} [/tex]
[tex] \frac{48 \times 9}{10 \times 16} = \frac{12b}{10} \times \frac{3}{20} [/tex]
[tex] \frac{432}{160} = \frac{36b}{200} [/tex]
[tex]432 \times 200 = 160 \times 36b[/tex]
