Help: Justify why one relation is a function and why the other is not. Relation 1:
(1,2) (2,4) (3,6) (4,8)
Relation 2: (1, 3), (4, 2), (7, 1), (4,
Relation 1 is a function because we don't have any repeated x values. Each input goes to exactly one output.
On the other hand, relation 2 is not a function because x = 4 repeats itself. The input x = 4 leads to more than one output.

Explanation:
Let point N be at the intersection of the horizontal line and segment JM.
We can prove the right triangles JNK and MNK are congruent using the hypotenuse leg (HL) rule. This in turn means JN = NM through the use of CPCTC.
In other words, JN = NM because the horizontal line is the perpendicular bisector of JM.
So,
JM = JN + NM
JM = NM + NM
JM = 2*NM
JM = 2*7.1
JM = 14.2
Answer:
JM = 14.2
Step-by-step explanation:
Given JK = MK then Δ JKM is isosceles.
The line through K is a perpendicular bisector of JM , so
JM = 2 × 7.1 = 14.2
solve one step equation

explain why 256 + 4 is equivalent to (200 + 4) + (40+4) + (164)
The expression 256 + 4 is equivalent to (200 + 4) + (40+4) + (16+4) according to distributive and commutative property of addition.
Given the expression 256 + 4. This can be solved using the partial sum expressed as:
256 + 4
256 + 4
= (200 + 40 + 16) + 4
According to the commutative property, A+B = B+A
The arrangement does not affect the result. Hence;
(200 + 40 + 16) + 4 = 4 + (200 + 40 + 16)Using the distributive law;
4 +(200 + 40 + 16) = (200 + 4) + (40 + 4) + (16 + 4)
Hence the expression 256 + 4 is equivalent to (200 + 4) + (40+4) + (16+4) according to distributive and commutative property of addition.

Answer:
-7.5x -12.5, x < -17.5x +2.5, x ≥ -1Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
for (x+1) < 0
y = -7.5(x +1) -5 = -7.5x -12.5
for (x+1) ≥ 0
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...
[tex]y=\begin{cases}-7.5x-12.5,&\text{if }x<-1\\7.5x+2.5,&\text{if }x\ge-1\end{cases}[/tex]
solve: -4(-6x-3)+4x=3
Answer:
x=-9/28
Step-by-step explanation:
-4(-6x-3)+4x=3
24x+12+4x=3
28x+12=3
28x=-9
x=-9/28
Answer:
x = -9/28
Step-by-step explanation:
-4(-6x - 3) + 4x = 3=> 24x + 12 + 4x = 3=> 28x + 12 = 3=> 28x = 3 - 12=> 28x = -9=> x = -9/28Therefore, the solution is 'x = -9/28'.

Jodie made a New Year's resolution to learn how to play the violin. She bought an
Introduction to Violin class pack from the Noble Notes music shop, which covers the cost of
12 violin lessons. She also paid $25 to rent a violin. In all, Jodie paid $385. How much does
each violin lesson cost?
Answer:
$30
Step-by-step explanation:
If x is the cost of a lesson, the total cost of Jodie's purchase is ...
cost of lessons + rental cost = total cost
12x + 25 = 385
12x = 360 . . . . . . . subtract 25
x = 30 . . . . . . . . . . divide by 12

5(2x-2)=8x: what is the value of x?
Answer:
5
Step-by-step explanation:

What is the total selling price before tax?
How much is sales tax did you pay?
What was your total cost?
The total selling price before tax is $261.96.
The sales tax paid is $15.72.
The total cost is $277.68.
The total selling price before tax is the sum of the prices of the WWE 2K21, Starbucks Vanilla Coffee, new Keurig K550 and the jeans
$49.99 + $13.99 + $179.99 + $17.99 = $261.96.
Sales tax is the amount of money levied when a good or service is purchased. It is a percentage of the price of an item
Sales tax = tax rate x cost
6% x $261.96 = $15.72
The total price paid is the sum of the sales tax and the total selling price.
$15.72 + $261.96 = $277.68

Answer:
The function is 200+50t (t= # of months)
Step-by-step explanation:
The best way to do this is to look at the question, and see no matter what, we have to pay 200 dollars to start. After which, they charge 50 bucks a month. Knowing this, we can make a function using f(x). Let C(t)= cost. Included is that graph. So for these questions, we need to see that there is an independent and a dependent variable, and we need to see that cost is affected by time. Hope this helps.

What error did she make? StartFraction part Over whole EndFraction = StartFraction 70 times 8,750 Over 100 times 8,750 EndFraction = StartFraction 612,500 Over 875,000 EndFraction.
Answer:
1,250,000
Step-by-step explanation:
875,000 sandals account for 70% of the total pairs sold.
875,000/7 = 125,000
125,000 accounts for 10%.
125,000 * 10 = 1,250,000.
1,250,000 accounts for 100%.
The company sells pairs of shoes in June is 612,500
