Find the measure. (Lesson 5-1)
TQ
If TQ = 2x - 6 and RQ = x + 3 then the measure of TQ = 12.
What is Perpendicular Bisector Theorem?The perpendicular bisector theorem states that if a point is on a segment's perpendicular bisector, it is equidistant from the segment's endpoints.
According to the perpendicular bisector theorem, any point on the perpendicular bisector is equidistant from both ends of the line segment on which it is drawn. If a pillar stands at an angle in the center of a bridge, all of its points will be equidistant from the bridge's end points.
Where, TQ = 2x - 6 and RQ = x + 3
By the Perpendicular Bisector Theorem, RQ = TQ.
2x - 6 = x + 3
x = 9
Substitute the value of x in TQ, we get
TQ = 2(9) - 6
= 18 - 6
= 12
Therefore, the value of TQ = 12.

The solution of the equation is (-3, 6).
How to solve system of equation?-3c - 3y = -9
5c - 2y = -27
Therefore, using elimination method, the equation can be solved as follows:
multiply equation(ii) by 1.5(3 /2)
-3c - 3y = -9
7.5c - 3y = - 40.5
subtract equation(i) from equation(ii)
10.5c = - 31.5
divide both sides by 10.5
c = -31.5 / 10.5
c = -3
Therefore,
5c - 2y = -27
5(-3) - 2y = -27
-15 - 2y = -27
-2y = -27 + 15
-2y = - 12
divide both sides by -2
y = -12 / -2
y = 6

The angle measurements in the diagram are represented by the following expressions.
B = 3x + 53°
A= 6x - 35°
Solve for x and then find the measure of A:
The value of x is 18° and the value of the angles A and B are 73° and 107° respectively.
We are given the angle measurements as:
A = (6x - 35)°
B = (3x + 53)°
We need to solve for x and find the values of A and B
We know that co- interior angles are supplementary.
So, we get that:
A + B = 180°
Substituting the values of A and B in the above equation, we get that:
6 x - 35 + 3 x + 53 = 180
9 x + 18 = 180
9 x = 180 - 18
9 x = 162
x = 162 / 9
x = 18
So, we now get that:
A = (6x - 35)°
A = (6(18) - 35)°
A =(108 - 35)°
A = 73°
B = (3 x + 53)°
B = (3 (18) + 53)°
B = ( 54 + 53 )°
B = 107°
Therefore, we get that the value of x is 18° and the value of the angles A and B are 73° and 107° respectively.

Yes, the results of dividing X by a negative value and dividing X by a positive value are different. If we divide X by a negative value, the result will be negative, and if we divide X by a positive value, the result will be positive.
For instance:
It is true that 8 > 2 is unequal.
Divide both sides by 2, then:
True inequality also exists when 4 > 1. Due to the fact that we divided by a positive number, the inequality symbol remained.
Let's begin once more with
8 > 2, and apply a -2 to both sides.
-4 > -1 is erroneous. The inequality is no longer valid if the inequality sign changes when both sides are divided by a negative integer. When dividing both sides by a negative integer, the inequality sign must be changed in order to maintain its validity.

The ladder she is using is 24 feet long and she puts the base of the ladder 13 feet away from the house in order to avoid her flower gardens. How high up the side of her house does the ladder reach? Round to the nearest tenth, if necessary.
The ladder can reach 21.17 feet high up of Denise's house.
Given,
The length of ladder Denise used to clean the outside of her second story windows = 24 feet
The distance between the base of the ladder and house = 13 feet
We have to find the height of the house which the ladder can reach:
For that we can use Pythagorean Theorem.
That is,
Hypotenuse² = Altitude² + Base²
Here,
Hypotenuse is the length of the ladder = 24 feet
Altitude is the height of the house ladder can reach = x
Base is the distance between base of the ladder and house = 13 feet
Therefore,
24² = x² + 13²
576 = x² + 169
x² = 576 - 169
x² = 407
x = [tex]\sqrt{407}[/tex]

A car manufacturer is reducing the number of incidents with the transmission by issuing a voluntary recall. During week 10 of the recall, the manufacturer fixed 200 cars. In week 15, the manufacturer fixed 175 cars. Assume that the reduction in the number of cars each week is linear. Write an equation in function form to show the number of cars seen each week by the mechanic.
f(x) = 5x + 250
f(x) = −5x + 250
f(x) = 10x + 200
f(x) = −10x + 200
Answer :f(x) = -5x + 250
Step-by-step explanation:
* Lets explain how to solve the problem
- In week 10 the manufacturer fixed 200 cars
- In week 15, the manufacturer fixed 175 cars
- the reduction in the number of cars each week is linear
- The form of the linear equation is y = mx + c, where m is the slope of
the line which represent the equation and c is the y-intercept
- The slope of the line m =
where (x1 , y1) and (x2 , y2) are two points on the line
* Lets solve the problem
- Assume that the weeks' number is x and the cars' number is y
∴ (10 , 200) and (15 , 175) are two points on the line which represent
the linear equation between the cars' numbers and the weeks
numbers
∵ Point (x1 , y1) is (10 , 200) and point (x2 , y2) is (15 , 175)
∴ x1 = 10 , x2 = 15 and y1 = 200 and y2 = 175
- Use the rule of the slope above to find m
∴
- Substitute the value of x in the form of the linear equation above
∴ y = -5x + c
- To find c substitute x and y by one the coordinates of one of the
two points
∵ x = 10 when y = 200
∴ 200 = -5(10) + c
∴ 200 = -50 + c
- Add 50 to both sides
∴ 250 = c
- Substitute the value of c by 250
∴ y = -5x + 250, where the number of cars seen each week is y and
x is the number of the week
∵ f(x) = y
∴ f(x) = -5x + 250
