Answer:
s = (-23/65)
Step-by-step explanation:
7 -2
------ = -------
(s + 8) (9s + 1)
7 (9s + 1) -2 (s + 8)
------ = -------
(s + 8) (9s + 1) (9s + 1) (s + 8)
7 (9s + 1) -2 (s + 8)
(------------------ = ---------------------) ((9s + 1) (s + 8))
(s + 8) (9s + 1) (9s + 1) (s + 8)
7 (9s + 1) = -2 (s + 8)
63s + 7 = -2s - 16
+2s +2s
65s + 7 = -16
-7 -7
65s = -23
÷65s ÷65s
s = (-23/65)
find a proposition with three variable p, q and r that is true when at most one of the three variables is true, and false otherwise
Three variable p, q and r that is true when at most one of the three variables is true.
How do you identify a proposition?
Propositions are the name for certain types of phrases. A proposition is said to have a "true" truth value if it is true; a "false" truth value if it is untrue. Propositions include statements like "Grass is green" and "2 + 5 = 5". The first claim is true, whereas the second is wrong in terms of truth value.Atmost means maximum.
We have three variables: p,q and r. Maximum one of the three variable is true. However we dont know which variable is true.
Case 1: No variable is true : ¬p ∧¬q∧¬r
Case 2 : p variable is true: p ∧¬q∧¬r
Case 3: q variable is true : ¬p ∧q∧¬r
Case 4 : r variable is true : ¬p ∧¬q∧r
One of the 4 cases has to be true . Thus Case1 or Case 2 or Case3 or Case 4 is true. So we need to take comjuction of the propsitions in each case.
(¬p ∧¬q∧¬r) v (p ∧¬q∧¬r) v (¬p ∧q∧¬r) v (¬p ∧¬q∧r)

Fatoumata has a collection of 280 coins. How many coins represent 20% of her
collection?
Divide/scale down to solve for the missing percent.
The coins that represent the 20 5 of her coins that is 280 are 56 coins.
We know that:
Fatoumata has a collection of 280 coins.
Now, we need to tell how many coins will be its 20 %.
For this we will calculate 20 percent of 280
So, number of coins = N will be:
N = 20 % of 280
N = 20 % × 280
N = 20 / 100 × 280
N = 2 × 28
N = 56 coins
Therefore, we get that, the coins that represent the 20 5 of her coins that is 280 are 56 coins.

Cookies are sold in the lunchroom for $2. Ana wants to buy cookies for a group of her friends. If she has $20, write an inequality to show the number of cookies cc she can buy. Use the variable c
As a inequality
Answer:
2c < 20
Step-by-step explanation:
$2 is the price per cookie so 2c is per every cookie, you multiply by 2 to get the price.
Ana only has $20 so the amount of money she spends has to be less then 20 so the inequality would be 2c < 20
The midpoint of AB is M(3, -1). If the coordinates of A are (5, 1) what are the coordinates of B?
The coordinates of B is (1,-3) .
A midpoint formula is a formula used to identify the midpoint between two data points. Except for geometry, research in economics uses this calculation to calculate elastic moduli, etc.The Midpoint Formula is given by [tex](x, y)=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex] where, [tex](x_1,y_1)[/tex] are the coordinates of the first point and [tex](x_2,y_2)[/tex] are the coordinates of the second point.It is given that midpoint of AB is (3, -1) and coordinates of A is (5, 1) .
Let the coordinate of B be (x, y) .
By using midpoint formula , we get
[tex](3, -1)=(\frac{5+x}{2} , \frac{y+1}{2} )\\[/tex]
On comparing , we get the x- coordinate

Explain how you can use a straightedge and a compass to construct an angle that is both congruent.
The construction of two congruent angles using a scale and compass can be done by applying the prerequisite knowledge of construction.
What is an angle?
A geometrical figure formed by using two rays, which are known as the sides of angle. These sides share a common vertex. Angle can be of various types including acute, obtuse, reflex, right, etc.
Explanation of constructing an angle using a scale and compass that is both congruent
Start drawing a line with the scale
Then, using this line or edge of the given angle to construct another corner, with the same vertex, let's call it O
Mark an arc across the sides of the corner using compass
Name the points as A and B, where the arc intersects and extend that arc beyond B
Open the compass to length of AB by setting it to the point B, and then mark an arc that intersects the first arc at point C.
Forthwith, wwe have two congruent components, AB = BC.
As the distance is OA = OB = OC, therefore, ∠AOB and ∠BOC are congruent.
Hence, this is the way of constructing congruent angles using a scale and a compass.

Let g(x)=-1/2x+ 6 and h (x) =g(x)-3 which statement descibes the graph of h(x)?
The statement describing the graph of h(x) is "The graph of h(x) is a vertical translation of the graph of g(x) down 3 units".
In the question, are given two graphs g(x) = - (1/2)x + 6, and h(x) = g(x) - 3.
We are asked for the statement that best describes h(x).
Now, h(x) = g(x) - 3, can be seen as the translation of g(x).
For any graph m(x), n(x) is its translation if n(x) = m(x + p) + q.
The translation is vertical is q ≠ 0, and horizontal when p ≠ 0. Also,
if p > 0, then the horizontal translation is p units right,if p < 0, then the horizonal translation is |p| units left,if q > 0, then the vertical translation is q units up, andif q < 0, then the vertical translation is |q| units down.For, h(x) = g(x) - 3, when we compare it with n(x) = m(x + p) + q, we have p = 0, and q = -3.
Since, q ≠ 0, we have vertical translation, and since q < 0, the translation is |q| units down.
Thus, The statement describing the graph of h(x) is "The graph of h(x) is a vertical translation of the graph of g(x) down 3 units".

How to find the how many teenagers went to the zoo?given that
Tickets to the zoo cost $4 for children.
Tickets to the zoo cost $5 for teenagers.
Tickets to the zoo cost $6 for adults.
1200 people come to the zoo every day.
on a certian day, the total revenue at the zoo was $5300.
Let the number of adults be x.
The number of teenagers be y.
and the number of children that went to the zoo 8y/3.
Consider the question
1200 people come to the zoo every day.
x + y + 8y/3 = 1200
now, take L.C.M between y and 8y/3
[tex]x + \frac{(3y + 8y)}{3} = 1200 \\ x + \frac{11y}{3} = 1200[/tex]
now multiply with 3 to this equation.
3x + 11y = 3600 .......................(1)
tickets to the zoo cost $4 for children, $5 for teenagers and $6 for adults.
according to the question
6x + 5y + 32y/3 = 5300
Now take the L.C.M between 5y and 32y/3
6x + 47y/3 = 5300
now multiply with 3 to this equation.
18x + 47y = 15900 ...................(2)
now, multiply equation (1) with 6
18x + 66y = 21600 .....................(3)
now, subtract equation (1) in equation (2)
(18x - 18x) + (66y - 47y) = (21600 - 15900)
19y = 5700
y = 5700/19
y = 300
