There are two questions :v
Answer:
Step-by-step explanation:
One
v^2 - 16
This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.
The square root of v^2 = v
The square root of 16 = 4
You get (v + 4)(v - 4)
Let's see what happens when you expand it.
v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16Look what happens when you add these 4 terms together.
v^2 - 4v + 4v - 16v^2 - 16is what is left. The two middle terms cancel out.
Two
This one is a perfect square
w^2 + 16w + 64
(w + 8)(w + 8)
Notice both factors are the same. You might wonder how I new that.
w^2 is a perfect square so take the square root. .... v
64 is a perfect square so take the square root ..... 8
Now you have to work backwards to see if it is right.
w*w = w^2w*8 = 8w8*w = 8w8^2 = 64Adding you get w^2 + 16w + 64 which is what you started with.

Given:
The table of values.
v and x are in direct proportion.
To find:
The formula connecting v and x.
Solution:
(a)
v and x are in direct proportion.
[tex]v\propto x[/tex]
[tex]v=kx[/tex] ...(i)
Where, k is the constant of proportionality.
Putting v=13.6 and x=32.64, we get
[tex]13.6=k(32.64)[/tex]
[tex]\dfrac{13.6}{32.64}=k[/tex]
[tex]\dfrac{5}{12}=k[/tex]
Putting the value of k in (i), we get
[tex]v=\dfrac{5}{12}x[/tex]
Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].
(b)
Putting v=n and x=8.16, we get
[tex]n=\dfrac{5}{12}(8.16)[/tex]
[tex]n=3.4[/tex]
Therefore, the value of n is 3.4.

The system x-6y=4, 3x-18y=4 has no solution.
Change one constant or coefficient to make a new system with an infinite number of solutions.
Answer:
x - 6y = 4, 3x - 18y = 12Step-by-step explanation:
If we multiply the first equation by 3 we get the same left sides in both equations:
3x - 18y = 12
3x - 18y = 4
To make system with an infinite number of solutions we need to make the left sides the same as well.
The required resulting equation that gives infinite solution will be x-6y= 3 and 3x-18y= 12
System of equationsSystem of equations can have difference kinds of solutions ranging from no solution, infinite number of solutions and real solutions.
For the system of equation that has infinite number of solutions, the two equations must be equal.
Given the system of equations
x-6y=4,
3x-18y=4
For the equation to have infinite number of solutions, we need to multiply the constant in equation 2 by 3 to have 4(3) = 12
Hence the required resulting equation that gives infinite solution will be x-6y= 3 and 3x-18y= 12

During the fall, you charge $10 to go to a house
and rake the leaves and an additional $8 for
every hour that you rake the yard. If you earned
$42, how many hours did you spend raking the
leaves?
Answer:
4 hours
Step-by-step explanation:
you take 42-10 because you take the total you made minus the $10 you chare to go to the house
then you take 32 divided by 8 for each hour spent
= 4 hours spent raking
If he earned $42 he spent 4 hours raking the leaves
During a fall he charges $10 to go to a house and rake the leaves and an additional $8 for every hour that he rakes the yard.
Therefore, the equation can be represented as follows;
Linear equationy = 8x + 10where
x = number of hours
y = total charges
Therefore, If he earn $42 the number of hours worked can be calculated as follows:
42 = 8x + 108x = 42 - 10
8x = 32
x = 32 / 8
x = 4
Therefore, he works 4 hours to earn a total of $42

PLEASE HELP
B. Engine Repair is more likely to be paid for with a credit card. Option B is correct
It is to be determined Which of these purchases is more likely to be paid for with a credit card
Parking fee B. Engine repair C. Soda D. Lotto ticket
A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.
Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.
Thus, B. Engine Repair is more likely to be paid for with a credit card. Option B is correct

A fair coin was flipped 50 times. It landed on heads 29 times.
What is the experimental probability that the coin landed on tails?
Answer:
21/50, 42%
Step-by-step explanation:
The total times the coin was flipped is 50 and the number of times it landed on tails is 50-29=21. So we need to divide 21 by 50, which gives us 42%.
