Please help me with this question
Answer:
First Row: Given
Second Row: Definition of Regular Polygon
Third Row: Definition of Congruence In Terms of Rigid Motion
Fourth Row: Definition of Regular Polygon
Fifth Row: SAS Triangle Congruence Theorem
Sixth Row: CPCTC
Step-by-step explanation:
This is a basic proof in order to prove that verticals of a polygon are congruent. This should be the right answer since it's the only thing that makes sense to me. I really hope this helps you and thanks for being patient! I've been doing geometry and we have to prove everything we claim in a proof just like this one. However, there was one I kind of guessed on (the third row), but I think it should be correct! I saw from the photo that you have a check answer on the bottom of your screen. Just check the answers that I have for you now and if something is wrong, then we can continue talking about it! Hope this helps!! :)
HELLO HUMANS! QUICK QUESTION. WILL MARK AS BRAINLIEST!
How do you solve for the slope of a graph that isn't straight? How would I solve the slope for this?
9514 1404 393
Answer:
use the slope formula
Step-by-step explanation:
Usually, you are asked for an average slope over some interval. The slope is calculated on that interval the same as it would be if you were given two points, one at each end of the interval.
m = (y2 -y1)/(x2 -x1)
For example, if you wanted to know the slope on the interval [1, 2] hours, the points you would use would be ...
(hours, miles) = (1, 25) and (2, 75)
The corresponding slope on that interval is ...
m = (75 -25)/(2 -1) = 50 . . . . miles per hour
__
You can identify four (4) regions on this graph in which the slope is constant:
(0, 1) . . . slope is 25 mph
(1, 2) . . . slope is 50 mph, as computed above
(2, 3) . . . slope is 0 (the rider has stopped)
(3, 5) . . . slope is 25 mph
Over different intervals, you need to identify the points involved and use the formula to compute the average slope.

5x+18=7x-6 what’s the answer?
Answer:
x = 12
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
5x + 18 = 7x - 6
Step 2: Solve for x
Subtract 5x on both sides: 18 = 2x - 6Add 6 to both sides: 24 = 2xDivide both sides by 2: 12 = xRewrite: x = 12Step 3: Check
Plug in x to verify it's a solution.
Substitute: 5(12) + 18 = 7(12) - 6Multiply: 60 + 18 = 84 - 6Add/Subtract: 78 = 78And we have our final answer!

Answer:
31.01, 180.8, 0.2, 15501
Step-by-step explanation:
Puzzle 1:
The first rule takes out 301
The second rule has to have a 1 in the units place so that takes out 3.1, 3.101, and 30.1
The 3rd rule takes out 1.01, and 1.03
Rule 4, is self explanatory, so it takes out 31.3
and the last rule takes out 31.1 bc there is no hundredths column
That leaves you with 31.01
Puzzle 2:
Rule 1 takes out 18180
Rule 2, self explanatory, takes out 180
Rule 3 takes out numbers less than 18 so 1.81 and 0.18
Rule 4 takes out 18.01, 1800, 188, and 18.8
That leaves you with 180.8
Puzzle 3:
Rule 1 takes out 0.24, 0.5, and 2.02
Rule 2 takes out 0.15
Rule 3 takes out 0.02, 0.01 and 0.1 (bc it just says greater than and not equal to so it takes this one out)
Rule 4 takes out 0.12
That leaves you with 0.2
Puzzle 4:
Rule 1 takes out 45000
Rule 2 takes out 5401, 5444, and 4544
Rule 3 takes out 5454
Rule 4 does not take out any because all the remaining numbers ( 14500, 15501, 14534, and 10500) have 5 hundreds
Rule 5 takes out 14500, 14534, and 10500
That leaves you with 15501
Hope this helped :)

Find the are of a square with side length x when x is equal to the given value. Are the area of a square and the length of its side directly proportional? Justify your answer.
x = 10in
Answer:
100 in²Step-by-step explanation:
Area formula
A = x²As per formula the area of a square and length of side are directly proportional
When x = 10 in, area is
A = 10² = 100 in²Express -4/-7 as a rational numbers with denominator.
1. -28
2. 7
3. 35
Step-by-step explanation:
1. -28
-4/-7 × -1/4
4/7 × -1/4 = -4/28
2. 7
-4/-7 × 1/1
4/7 × 1/1 = 4/7
3. 35
-4/-7 × 1/5
4/7 × 1/5 = 4/35

The cost of 3 pounds of grapes is $6.57. What is the constant of proportionality that relates the cost in dollars, y, to the number of pounds of grapes, x?
Answer:
$2.19
Step-by-step explanation:
Given that :
Cost of 3 pounds of grape = $6.57
Cost in dollars = y ; number of pounds = x
Cost in dollars α number of pounds
Cost in dollars = k * number of pounds
k = constant of proportionality
$6.57 = k * 3
$6.57 = 3k
Divide both sides by 3
6.57 / 3 = 3k/ 3
2.19 = k
k = $2.19

x pounds of Repperts chocolate valued at $3.50 per pound is mixed with y pounds of Godiva
chocolate valued at $4.30 per pound to produce 10 pounds of a mixture selling for $39. Find x
and y, the number of pounds of each type of chocolate. write two equations and solve using elimination
!!!!PLEASE HELP!!!!
Answer:
5 pounds eachStep-by-step explanation:
Required equations:
x + y = 103.50x + 4.30y = 39Substitute x in the second equation:
x = 10 - ySolve for y:
3.5(10 - y) + 4.3y = 3935 - 3.5y + 4.3y = 390.8y = 4y = 4/0.8y = 5Then
x = 10 - 5 = 55 pounds each

Step-by-step explanation:
The slope is negative 2 because the way the line is pointing, and the y-intercept is 1.
b) Factorise
Factorise y2 + 2y - 24
Answer:
(y + 6)(y - 4)
Step-by-step explanation:
Factor the following:
[tex] \longrightarrow [/tex] y² + 2y - 24
The factors of -24 that sum to 2 are 6 and -4.
So,
[tex] \longrightarrow [/tex] y² + (6 - 4)y -24
[tex] \longrightarrow [/tex] y² + 6y - 4y - 24
[tex] \longrightarrow [/tex] y(y + 6) - 4(y + 6)
[tex] \longrightarrow [/tex] (y + 6)(y - 4)
Answer:
( y-4) ( y+6)
Step-by-step explanation:
= y^2 + ( 6 - 4)y - 24
= y^2 + 6y - 4y - 24
= y( y + 6) - 4(y + 6)
= ( y - 4 ) ( y + 6)
