Which line is the graph of y=
x + 1?

line a
line b
line c
line d

Answer:

No, it is NOT a function.

Step-by-step explanation:

A functions' inputs are assigned to exactly one output.

We are given the points:

{(8,2) (4,-3) (6,4) (8,1)}

The input of 8 is repeating.

The given relation is not a function.  

Hope this helps!

===================================================

Explanation:

d dollars = 100d cents

for example, if d = 4, then,

4 dollars = 100*d = 100*4 = 400 cents

So Kim starts off with 100d cents.

She buys 'a' apples, where 'a' is a placeholder for the number of apples. If a = 5, then she bought 5 apples and spends 12*a = 12*5 = 60 cents. In general, she spends 12a cents buying 'a' apples.

Similarly, she spends 18b cents buying b bananas. The letter b is the placeholder for the number of bananas.

Overall, Kim spends 12a+18b cents for buying that amount of apples and bananas. Subtract this expression from 100d to find out how much money she'll have left over.

100d - (12a+18b) = 100d-12a-18b

This left over amount is in cents. If you want to convert to dollars, then you would need to divide by 100.

Answer:7

Step-by-step explanation:

Answer:

No. Each toss is independent so it is NOT more likely to come up heads the next time.

Step-by-step explanation:

That is the answer. Hope it helps

Answer:

B is the correct answer

Step-by-step explanation:

becasue if you solve this you get (0,0) (1,20) and (2,40) so b is the correct answer

Answer:

You first need to know what number 6 4/5 is, which is 6.8. To figure it out, you multiply 6 by 5 then add 4 and put the number you get on top of the fraction so it would be 34/5 = 6.8

6.9 is the answer

6.9 is bigger than 6.8 and smaller than 7

Answer: It think that 3 is adjacent to 5

Answer:

No, it is not

Step-by-step explanation:

Here, we want to check if what we have is a function

For a relation to be a function, the mapping must be one to one or many to one

This mean, for every x there must be one y or for every y, there must can be multiple x

But never is it that there are many y for a single x

Looking at the value 0

on the domain, we can see -2 and 1 as the values

Thus, this is not a function

Answer:

For 13 the slope is 0

Step-by-step explanation:

I can't see 12 nor 11, but 13 is a zero slope because horizonal lines have 0 slope.

Answer:

The sinusoidal axis is the neutral horizontal line that lies between the crests and the troughs (or peaks and valleys if you prefer). ... Instead, it would still be the horizontal line directly between the crests and troughs which is also the average of the maximum and minimum values

Step 2: Simplify

Answer:

[tex]\huge\boxed{8s}[/tex]

Step-by-step explanation:

Expression can be broken down into a couple of parts.

When we have multiple terms with the same variable, we can perform operations on them assuming they have the same variable - for example, 5x + 6x = 11x, as 5+6=11.

We can apply the same logic here, however, note that adding a negative is the same as subtracting a positive. For example, 5 + -2 is the same as 5-2.

[tex]10 - 2 = 8[/tex]

Therefore, our final expression is [tex]8s[/tex].

Answer:

13.7

Step-by-step explanation:

Pythagorean theorem converse

Answer:

The value of x is 13.7.

Step-by-step explanation:

☆We are going to use the Pythagorean theorem to solve this.

☆Pythagorean Theorem:

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

☆Remmeber: a = leg, b = leg, c = hypotenuse or the diagonal.

☆Let's plug in according to the pythagorean theorem and solve!

[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {9.2}^{2} = {16.5}^{2} \\ {x}^{2} + 84.64 = 272.25 \\ \frac{ \: \: \: \: \: \: \: \: - 84.64 = - 84.64}{ {x}^{2} = \sqrt{187.61} } \\ x = 13.7[/tex]

Answer:

[tex] \frac{6}{x} = \frac{5}{y} \\ 6y = 5x \\ Answer \frac{6}{5} = \frac{x}{y} [/tex]

Answer:

161.75

Step-by-step explanation:

45.28 divided by 7 = 6.47

6.47 per cande

6.47 times 25 = 161.75

For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)

#9-Step by step

Q=25[tex]\pi[/tex]h

divide 25[tex]\pi[/tex] on both sides of the equation

Q/25[tex]\pi[/tex]=h

h=Q/25[tex]\pi[/tex]

Since his can't be simplified any further this is your answer

#11. y=7m+6

First subtract 6 over to the other side

y-6=7m

then divide the 7 over

(y-6)/7=m

m=(y-6)/7

#13 A=(Z+7)3

Divide the three over to the other side of the equation

A/3=Z+7

Now the 7 is free to be subtracted from both sides

(A/3)-7=Z

#17. (2x/5)-9=6

First add 9 to both sides

2x/5=6+9

2x/5=15

Multiply both sides of the equation by 5

2x=5(15)

2x=75

Divide by 2

x=75/2

x=37.5
