<h3>Answer:  Choice C.   (-1, -5)</h3>

Explanation:

The reflection rule we use is

(x,y) \to (-x, y)

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.

Therefore, (1, -5) \to (-1, -5)

Which number is represented by point E on the graph?
zavuch27 [327]

Answer:

It'll be -0.25

Step-by-step explanation:

Notice how it is to the left of zero, anything to the left of zero is negative. With that in mind, we can eliminate A. The half mark between 0 and -1 represents 0.50, and since it goes by quarters, the E is at the first quarter, which is 0.25. Hopefully this helps!

13/4 would be 3 1/4. this is because 4 can go into 13 3 times leaving 1/4 left over. hence making it a mixed number. as a whole number it would be 3.25 because 4 can go into 13 3 times and 1/4 is .25, hope this helps!:)

P(x)equals=​R(x)minus−​C(x). Given ​R(x)equals=59 x minus 0.3 x squared59x−0.3x2 and Upper C left parenthesis x right parenthesi
Deffense [45]

Answer:

P(x)=-0.3x^2+56x-14  

Step-by-step explanation:

The given functions are

R(x)=59x-0.3x^2

C(x)=3x+14

It is given that

P(x)=R(x)-C(x)

Substitute the values of given functions in the above equation.

P(x)=59x-0.3x^2-(3x+14)

P(x)=59x-0.3x^2-3x-14

Combine like terms.

P(x)=-0.3x^2+(59x-3x)-14

P(x)=-0.3x^2+56x-14  

Therefore, the required function is P(x)=-0.3x^2+56x-14   .
