2. Which of these graphs represents a function?

Answer:

m= -1/7  (slope)

b= -1 (y inter)

Step-by-step explanation:

Answer:

-4

Step-by-step explanation:

8+4y= -8

4y= -8 -8

4y= -16

divide both sides by the coeffient of the variable. in this case divide both sides by 4

y=-4

Answer:

y = -4

Step-by-step explanation:

8+4y= -8

4y = -8 -8

4y = -16

y = (-16) ÷ 4

y = -4

Answer:

[tex]y = 3(x +21)[/tex]

Step-by-step explanation:

Find the inverse this equation:

[tex]f(x) = (\frac{1}{3}x) - 7[/tex]

-Take the variable [tex]y[/tex] for [tex]f(x)[/tex], because both

[tex]y = (\frac{1}{3}x) - 7[/tex]

-Switch both variable [tex]x[/tex] and [tex]y[/tex] :

[tex]y = (\frac{1}{3}x) - 7[/tex]

[tex]x = (\frac{1}{3}y) - 7[/tex]

-Solve for [tex]y[/tex] :

[tex]x = (\frac{1}{3}y) - 7[/tex]

-Switch sides:

[tex]\frac{1}{3}y - 7 = x[/tex]

-Add both side of the equation by [tex]7[/tex] :

[tex]\frac{1}{3}y - 7 + 7 = x + 7[/tex]

[tex]\frac{1}{3}y = x + 7[/tex]

-Multiply both sides by [tex]3[/tex] :

[tex]\frac{\frac{1}{3}y}{\frac{1}{3} } = \frac{x + 7}{\frac{1}{3} }[/tex]

[tex]y = \frac{x + 7}{\frac{1}{3} }[/tex]

-Divide [tex]x + 7[/tex] by multiplying by [tex]\frac{1}{3}[/tex]

[tex]y = \frac{x + 7}{\frac{1}{3} }[/tex]

[tex]y = 3(x +21)[/tex]

Therefore, the answer is [tex]y = 3(x +21)[/tex].

Answer: 2 + 2   x =2

Step-by-step explanation:

x + 2

x=2

2+2

Hey there!☺

[tex]Answer:\boxed{4}[/tex]

[tex]Explanation:[/tex]

[tex]x+2[/tex] when x = 2

Since x is 2, you just have to add it with the number that you need to add with.

[tex]x+2\\x(2)+2=4\\2+2=4[/tex]

4 is your final answer.

Answer:

Fraction: 8 [tex]\frac{11}{20}[/tex]

Decimal: 8.55

Step-by-step explanation:

8 11/20 is the answer because:

1) Since 8 is the whole number, 8 wouldn't be part of the fraction

2) The numerator is the top number in the fraction, so 11 is at the top since 11 is the numerator

3) The denominator is the bottom number in the fraction, so 20 is at the top since 20 is the denominator

8.55 is the answer because:

1) Since 8 is the whole number, 8 would be in front of the decimal point

2) When you multiply the fractions, you have to multiply until you get a hundred. Therefore, 20*5 = 100 and 11*5 = 55

Hope this helps!

Answer:

9

Step-by-step explanation:

Empowerment is easy to know how to resolve one operation of this.

In empowerment there are 3 parts, base, exponent and power.

But in this case there is 1 additional, the sign, that is important to define the power.

In this case the 3 is the base, the exponent is 2, and the sign -

To resolve this operation you need to multiply the base by the times there are on the exponent, if there is a 2 like exponent, you multiply 2 times 3:

3x3 = 9

But because the sign, change the multiplication, if the sign is on base is:

-3x-3 = 9

The 2 operation give the same result because on negative rules, on multiplication, even negative numbers give always positive result and odd negative numbers give always negative result.

Then the power is 9

Answer: It is not a function.

Step-by-step explanation:

A function is something that "eats" an input and transforms it into an output.

We write them as y = f(x)

Where x is the input, and y is the output.

Now, a function has an important rule, for each input x, the function can only "transform it" (or map it) into only one possible output.

This means that, for example, if we have, for x = x1.

And a single

f(x1) = y1

f(x1) = y2

where y1 and y2 are different values.

Then this is not a function, because it is mapping the value x1 into two different outputs.

In this case, we would have:

f(Z) = A.

So Z is the input, but we know that a ZIP code works for an entire city, and in a given city we have lots of different street addresses, then for a single value of the input, Z, we have a lot of possible values of the output.

This means taht the set (Z, A) can not represent a function.
