Apply the distributive property to write an expression that is equivalent to expression P.
Answer:
2(3x-9)=6x-9 Distribute
6x-18=6x-9 combine like terms

Which is a solution to the linear inequality 2x-3y>6
A. (3,0)
B. (-3,1)
C. (3,-1)
Answer:
C ( 3,-1) is a solution
Step-by-step explanation:
2x-3y>6
Let x = 3
2(3) -3y >6
6 - 3y>6
Subtract 6
-3y >0
Divide by -3
-3y/-3 < 0/-3
y < 0
If x = 3 y must be less than 0
C ( 3,-1) is a solution

In a translation transformation all the points in the object are removed in a straight line in the same direction. The size, the shape and the orientation of the image are the same as that of the original object. Same orientation means that the object and imageare facing the same direction. Example: We describe a translation in terms of the number of units moved to the right or left and thenumber of units moved up or down. Example: Move the object 2 units to the right and 4 units up.

Complete the stem-and-leaf plot for the list of test grades.73, 42, 67, 78, 99, 84, 91, 82, 86, 94
The stem-and-leaf plot for the list of test grades is created below.
What is Stem and leaf plot?A stem-and-leaf plot is a graphical representation of data that organizes values into a format that displays both the individual data points and their corresponding frequency. It is a way to represent a set of numerical data visually.
To create a stem-and-leaf plot, we separate each number into a stem and a leaf. The stem represents the tens digit, and the leaf represents the ones digit.
Here is the completed stem-and-leaf plot for the given test grades:
4 | 2
6 | 7
7 | 3, 8, 8
8 | 2, 4, 6, 6
9 | 1, 4, 9
In this plot, the stem represents the tens digit, and the leaves represent the ones digit.
For example, the grade 73 is represented as 7 as the stem and 3 as the leaf. The grade 82 is represented as 8 as the stem and 2 as the leaf.

Step-by-step explanation:
To find the quadrent a coordinate pair is in:
1. look at the "x" value in the (x,y) pair
2. if its negetive go leftward and if its positive go rightward
3. once you have moved to the respective x location do the same thing with the y coordinate in the (x,y) pair
4. up is positive for y and down is negitive.
for example (3,3) would be 3 to the right and 3 up so its in the top right quadrent
(-3,-3) would be 3 left and 3 down so its in the bottom left
Max has a piece of luggage that weighs 23.4 pounds. Convert this weight into kilograms
Answer:
First, we must know that;
1 pound is roughly about 2.2 kilograms.Given this, multiply the pounds you are given by 2.2 kilograms since 2.2 kilograms make up one pound.
23.4(2.2)
= 51.48 kilograms
23.4 = pounds
2.2 = kilograms (that make up one single pound)

help me do examples for a function and a non function
Answer:
{(1,2) (3,4) (5,6)} and {(1,2) (1,4) (5,6)}
Step-by-step explanation:
you really want to think of a function as a vending machine. if you press B12 on a vending machine because thats where the chips are, only the chips should come out. in a function, the input value aka x (B12, what youre putting in) should only have one output value aka y, (the chips)
an example of a function would be {(1,2) (3,4) (5,6)}
an important thing to remember is that one output value can belong to multiple input values. there can be chips (output) in both B12 and C12 (inputs) BUT as i said before, there CANNOT be two outputs for one input. B12 cannot give you both chips and a drink.
using this, another example of a function would be {(1,2) (3,2) (5,2)}
an example of an non function would be {(1,2) (1,4) (5,6)} because x, the input value, has multiple output values which is not possible. the output of 1 can not be 2 and 4 at the same time which we can see in the (x,y) coordinates.

Find the average rate of change from x=4 to x=10 for the equation y=2x-3
Answer:
2
Step-by-step explanation:
The average rate of change of the equation during the interval 4 ≤ x ≤ 10
can be represented in this expression if f(x) is substituted for y:
[tex]\dfrac{f(10)-f(4)}{10-4}[/tex]
[tex]=\dfrac{17-5}{6}[/tex]
[tex]=\dfrac{12}{6}[/tex]
[tex]=2[/tex]
So, the average rate of change (AOC) is 2.
You also could just figure this out by looking at the slope. Since this is a linear equation, the AOC over any interval will always be the same as the slope, since the slope is constant.

Step-by-step explanation:
(You can do this differently, but I chose to do it like this)
First, convert the 1816 kilograms to pounds.
1816 kilograms = 4003.595 pounds
Then, we can divide 4003.595 pounds by 160 to figure out how many 160-pound people the balcony can hold.
4003.595 ÷ 160 ≈ 25.02
If the balcony holds 26 people, it will collapse, so the answer must be 25.

A parachutist's rate during a free fall reaches 162 kilometers per hour. What is this rate in meters per second? At this rate, how many meters will the parachutist fall during 10 seconds of free fall? Do not round your answers.
rate: (m/s)
distance fallen in 10 seconds:
Step-by-step explanation:
162 kilometers = 162000 meters
1 hour = 3600 seconds.
162,000 meters/3600 seconds=45 meters/second=45 m/s
45*10=450
Suppose P, Q, and R are points in the plane such that PQ=1.8, PR=8.2, and angle PQR=90 degrees. What is the area of triangle PQR$?
Answer:
7.2 sq units
Step-by-step explanation:
Seeing as this is a right triangle, and the hypotenuse and one leg is given, you can use the pythagorean formula to get the third side ([tex]\sqrt{8.2^2 - 1.8^2}[/tex]). Now that we have this leg, we can multiply this by 1.8, then divide it by two (area of triangle).

Answer:
x(angle A)=18.9 Angle B=94.5 Angle C=66.6
Step-by-step explanation:
Angle A+ angle B+ Angle C= 180
(x)+(5x)+(4x-9)= 180
add the x components: x+5x+4x= 10x
10x-9 =180
add 9 to each side to balance the equation
10x=189
Divide each side by 10 to get x
10x/10=x 189/10= 18.9
x=18.9
Put x back into the equations
B=5x B=5(18.9) B=94.5
C=4x-9 C=4(18.9)-9
C=66.6
Answer:
We first solve for x, then plug that value into all angle measures.
As selected in the first part,
m∠A + m∠B + m∠C = 180°,
We use this formula to solve for x.
Replace those angle variables with its actual equations, knowing that:
Angle A = x °Angle B = 5x°Angle C = 4x - 9°So, set up the equation:
m∠A + m∠B + m∠C = 180°,
x + (5x) + (4x - 9) = 180°
Solve for x;
x + (5x) + (4x - 9) = 180°
Group and combine like terms;
(5x + x + 4x) + (-9) = 180°
10x - 9 = 180°
Get rid of constants;
+9 +9
10x = 189°
Get rid of co-efficient;
÷10 ÷10
x = 18.9°, x is equal to 18.9°.
Now, plug the value of x into angle 'A':-
x °
(18.9) °
∠A = 18.9°.
Then, plug the value of x into angle 'B':-
5x°
5(18.9) °
94.5°
∠B = 94.5°.
Finally, plug the value of x into angle 'C':-
4x - 9°
4(18.9) - 9°
75.6 - 9°
66.6°
∠C = 66.6°.
