Since T is the midpoint of PQ, this means the smaller pieces PT and TQ must be equal. In other words, T divides PQ in half.
PT = TQ
5x+7 = 9x-9
5x-9x = -9-7
-4x = -16
x = -16/(-4)
x = 4
Use this to find each segment length.
PT = 5x+7 = 5(4)+7 = 20+7 = 27TQ = 9x-9 = 9(4)-9 = 36-9 = 27Both pieces are 27 units long, which confirms the answer.

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".

the water level of a lake fell by 11/2 inches during a 12/3-week long dry spell. Find the average rate at which the water level changed every week.
Every week, the water level dropped by 1.375 inches on average rate.
The average rate is what?
The ratio of "change in the function values" to "change in the interval endpoints" is referred to as the average rate of change of a function f(x) over an interval [a, b]. Specifically, [f(b) - f(a)] can be used to get the average rate of change (b - a). The average rate of change, represented by the symbol A(x), is, in other words, the "ratio of change in outputs to change in inputs." A(x) = (change in outputs), for example (change in inputs)
based on the available facts;
Detailed explanation:
A lake's water level dropped by -11/2 inches throughout the course of a 12-week dry period.
Total fall of water level = -11/2 inches = -5.5 inches
Time of fall = 12/3 week = 4 weeks
Average rate at which water level changed every week=Total fall of water level/Time of fall
=-5.5/4
=-1.375per inch every week
Average rate at which the water level changed every week = -1.375 inches

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.

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.

0.0001 is a very tiny possibility that you will get caught driving slower than the posted speed limit.
What is probability?Probability is a branch of mathematics that deals with the numerical representations of the likelihood that an event will occur or that a statement is true. A number between 0 and 1 is the probability of that an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
How can you calculate the probability?By simply dividing the actual favorable amount of possibilities by the entire number of possible outcomes, one can use the probability formula to determine the likelihood of an event.
According to the given data:Given,
radar speed detector is 0.56 mph.
inital speed = 33mph
final speed = 30mph
finding the probability that we clocked at below the speed limit.
so,
p(Z<(inital- final)/speed detector)
p(Z<(33-30)/0.56)
p(Z<5.35)

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)
