Answer: y=3 is a polynomial function? Yes. The equation y=3 represents the function that maps all x values to 3

Step-by-step explanation:

The equation y= 3 represents a horizontal line, which will have exactly one intersection point with any vertical line. So it passes the vertical line test for a function too.

A. Direct Variation

Step-by-step explanation:

I had the exact same answer on my test and I got this one correct

Answer:

Inverse Variation

Explanation:

While direct variation describes a linear relationship between two variables , inverse variation describes another kind of relationship. For two quantities with inverse variation, as one quantity increases, the other quantity decreases.

Answer:

x = -3y + 2

-3y = x - 2

f^-1(x) = y = -(x-2)/3

Step-by-step explanation:

The inverse here is just straight line so it is a function

Answer:

x= -3

Step-by-step explanation:

The slope is -1 so starting at the y-intercept going backwards, follow the line till you find y=7 and look at the x

One-third of the number is at least 5 units from 31. The number is 78.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that one-third of a number is at least 5 units from 31. The unknown number is x.

( 1 / 3 )x + 5 = 31

x + 15 = 31 x 3

x + 15 = 93

x = 93 - 15

x = 78

Therefore, one-third of the number is at least 5 units from 31. The number is 78.

a = 4, R = 147, T = 33

Step-by-step explanation:

find a

a/(a + 7) = (16/3)/(44/3)

a/(a + 7) = 16/44

44a = 16a + 112

44a - 16a = 112

28a = 112

a = 112/28

a = 4

find R

2x + 5 = 3x - 9

5 + 9 = 3x - 2x

14 = x

m ∠R = 180° - (2x + 5)

= 180 - (2(14) + 5)

= 180 - (28 + 5)

= 180 - 33

= 147°

find T

m ∠T = 3x - 9

= 3(14) - 9

= 42 - 9

= 33°

a) The piecewise function is:

[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]

[tex]C(n) = 15 + 1.1n, n > 20[/tex]

b) Applying the piecewise function, it is found that it will cost $40.

A piecewise function is a function that has different definitions based on the input.

Item a:

[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]

[tex]C(n) = 15 + 1.1n, n > 20[/tex]

Then, the piece-wise function is:

[tex]C(n) = 12 + 1.40n, n \leq 20[/tex]

[tex]C(n) = 15 + 1.1n, n > 20[/tex]

Item b:

Then:

[tex]C(20) = 12 + 1.4(20) = 12 + 28 = 40[/tex]

It will cost $40.

Answer:

Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?

A

Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.

B

С

Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.

Enzymes work equally well at the low and high ends of their temperature range but reaction rate drops quickly at the high end of their pH range

Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.

Answer:

[tex]\sqrt{10}[/tex]

Step-by-step explanation:

The distance between two points can be found using the Pythagorean Theorem [tex]a^{2} + b^{2} = c^{2}[/tex].

This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates ([tex]x_{2} -x_{1}[/tex]) and the height by the distance between the y coordinates ([tex]y_{2} - y_{1}[/tex]). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.

Answer: 9 hrs for 45cm of snow to fall

Step-by-step

If 30cm = 6 hrs

Then divide 30/6 to get the unit rate of the amount of snow per hr

Which is 5/1

So 5cm per hr

Then add 30+5+5+5 to get 45

And since we know 5cm equal 1 hr

Add the original amount of hours which is 6 plus 3 ones

Which is 6+1+1+1

In total, it will take 9 hrs for 45cm of snow to fall.

Answer:

y = x + -2.3

x = -y - 2.3 (but why would one need this?...)

Step-by-step explanation:

(6.1 - (-9.7))/(8.4 - (-7.4)) = 15.8/15.8 = 1

6.1 = 8.4 + b

b = -2.3
