Please help!!! Name the property of equality or congruence that justifies going from the first statement to the second statement.
Answers
Answer:
The property of equality that justifies going from the first statement to the second statement is;
Subtraction property of equality
Step-by-step explanation:
The given equation is presented here as follows;
AB + BC = 42
AB = 42 - BC
The above equation can be simplified as follows;
AB + BC = 42
AB + BC - BC = 42 - BC
(+ BC - BC = 0)
Therefore, we have;
AB + BC - BC = AB + 0 = AB = 42 - BC
AB = 42 - BC which is the subtraction property of equality
For the subtraction property of equality, when we subtract a value from one side of the equation, we must subtract the same value from the side of the equation as follows
Given that the letters a, b, and c represent any numbers
When we have;
a = b
Then we also must have;
a - c = b - c

b = 15c = 51c = 100b = 25.75Step-by-step explanation:
Using the Pythagoras theorem equation:
[tex]c^{2}=a^{2}+b^{2}[/tex]
Where 'c' is the hypotenuse and 'b' and 'a' the sides of the right triangle.
1) Here c = 17, a = 8 and b = ?
Then, using the above equation we can find the side b.
[tex]17^{2}=8^{2}+b^{2}[/tex]
[tex]b=\sqrt{225}[/tex]
[tex]b=15[/tex]
2) Here a = 24, b = 45 and c = ?
[tex]c=\sqrt{24^{2}+45^{2}}[/tex]
[tex]c=51[/tex]
3) Here a = 28, b = 96 and c = ?
[tex]c=\sqrt{28^{2}+96^{2}}[/tex]
[tex]c=100[/tex]
4) Here a = 17, b = ? and c = 28
[tex]b=\sqrt{28^{2}-11^{2}}[/tex]
[tex]b=25.75[/tex]
Just in the 4 case x is an altitude.

A. (–10, –10)
B. (–9, –6)
C. (–5, 1)
D. (1, 12)
E. (4, 7)
Answer:
[tex]B.\ (-9, -6)[/tex]
[tex]C.\ (-5, 1)[/tex]
[tex]D.\ (1, 12)[/tex]
Step-by-step explanation:
A relation is represented as:
[tex]R->\{(x_1,y_1),(x_2,y_2),(x_3,y_3)...(x_n,y_n)\}[/tex]
Where
[tex]x = domain[/tex]
[tex]y = range[/tex]
For a relation to be a function, the domain must be unique and must not be repeated.
In the given function,
[tex]\{(-9, 1), (-5, 2), (0, 7), (1, 3), (6, -10)\}[/tex]
The domains are [tex]\{-9,-5,0,1,6\}[/tex]
So, if (6,-10) is to be replaced;
The domain of the ordered pair that will replace it must not be any of [tex]\{-9,-5,0,1,6\}[/tex]
From the list of given options:
[tex]B.\ (-9, -6)[/tex]
[tex]C.\ (-5, 1)[/tex]
[tex]D.\ (1, 12)[/tex]
The above can not replace (6,-10) because their domain exist already.
Plz help I don’t understand how to find x?
Answers
Answer:
x = -4
Step-by-step explanation:
First lets add 82 + 55 which equals 137, then 137 +47 which equals 184
Now we know that a triangle equals 180 degrees (cannot go over 180), so this tells us x is a negitive number.
-x + 184 = 180
-x = -4
Another way to look at it is; 184 minus what equals 180? 4 does, so it translates into -4.

Emery earns money mowing his neighbors' lawns. He charges $1.25 per square yard for each lawn he mows. His neighbors, the Flores Family, hires Emery to mow their rectangular lawn. Emery records the dimensions of their lawn and calculates that he will charge them $21. The width of the Flores' rectangular lawn is 4 yards. What is the length, in yards, of the Flores' lawn?
Answers
Answer: 4.2 yards
Step-by-step explanation:
Let x = length of the Flores' lawn in yards.
Then, Area of lawn = 4x sq. yard [Area of rectangle = width x length , here width = 4 yds (given)]
Charge per square yard = $1.25
Charge for Flores lawn = 1.25 × (Area of lawn)
= 1.25 (4x)
= 5x
As per given,
[tex]5x=21\\\\\Rightarrow\ x=\dfrac{21}{5}\\\\\Rightarrow\ x=4.2[/tex]
Hence, the length of the Flores's lawn = 4.2 yards

Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall but its length is unknown. Each section will be a different color, so they need to know the area if each section. Write a expression for the total area of the wall. Explain how you came up with your expression.
Answers
Answer:
50
Step-by-step explanation:
5×10=50
The equation for the area of the wall can be written as [tex](10\times L)=10\times (L_T+ L_1+L_2+L_3+L_4)[/tex].
Given to us:
Todd and his friends are painting 5 equal sections of a wall. So,
total number of sections wall has = 5,
Height of the wall = 10 feet,
Also, we know;
area of rectangle = length x breadth,
area of wall = length x height,
So,
Area of wall = Area painted by Todd and his friends
height of the wall x Total length of the wall =
height of the wall x length of the wall painted by Todd
+ height of the wall x length of the wall painted by friend 1
+ height of the wall x length of the wall painted by friend 2
+ height of the wall x length of the wall painted by friend 3
+ height of the wall x length of the wall painted by friend 4
Therefore,
[tex](10\times L)=(10\times L_T)+(10\times L_1)+(10\times L_2)+(10\times L_3)+(10\times L_4)[/tex]
taking 10 as common,
[tex](10\times L)=10\times (L_T+ L_1+L_2+L_3+L_4)[/tex]
Hence, the equation for the area of the wall can be written as [tex](10\times L)=10\times (L_T+ L_1+L_2+L_3+L_4)[/tex].

What does rate of change mean? List 2 to 4 bullets below for BRAINLIEST ANSWER NEEDED ASAP!!!!
Answers
Answer: A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Step-by-step explanation: Hope this help
It tells us the average speed. For instance, if you move 10 meters in 4 seconds, then the average rate of change is 10/4 = 2.5 meters per second. This could apply to moving from one location to another.
It could also be used to describe how much work you can get done over time. For example, let's say you paint 5 square meters of a wall per hour. This is the speed at which you get the job done. After 1 hour, you've painted 5 square meters of wall. After 2 hours, you've painted 2*5 = 10 square meters, and so on.
Another example could be how a population is changing. If there are 100 animals at time 5 hours, then the population becomes 200 animals at time 10 hours, then the rate of change is (200-100)/(10-5) = 100/2 = 50 animals per hour. In other words, the population is going up by 50 animals for every hour.
