Answer:

y = 2x - 3

Step-by-step explanation:

5 = 2[4] + b

-3 = b

y = 2x - 3 → Parallel Equation

Parallel Lines have SIMILAR RATE OF CHANGES [SLOPES], so 2 remains the same.

I am joyous to assist you anytime.

A cheese pizza costs $5. Additional toppings cost $1.50 each. Write and graph an equation that represents the total cost $c$ (in

Triss [41]

Answer:

5 + 1.5x = total cost

Step-by-step explanation:

5 is for one pizza and x is for toppings. For every topping it is multiplied by 1.5. for example, if you have 2 toppings for one cheese pizza it would be 5 dollars + 1.5x2 which is 3 so 3+5=8$ in total.

After college you start a job earning $40,000 a year. You get a 6% raise each year.

alex41 [277]

Answers: A) $44,944
B) $50,499.0784

Math: Using the percentage calculator linked below 6% of $40,000 is $2,400. Since you're getting your second raise after your first and since it is a 6% raise from what you're getting paid at that time we add pay raise 1 to your starting pay before calculating the 6% for pay raise 2. $40,000+$2,400=$42,400. 6% of $42,400 is $2,544. $42,400+$2,544=$44,944, Since that is two pay raises that would be your earnings at the end of year two (answer A).
We continue calculating 6% then adding that onto the total before calculating it for the next year for problem B.
6% of $44,944 is $2,696.64. $44,944+$2,696.64=$47,640.64.
6% of $47,640.64 is $2,858.4384. $47,640.64+$2,858.4384=$50,499.0784. That's answer B.

Hopefully you can figure out C on your own! I feel a little bad for giving a partial answer but I think you can do this!

1. Which graph represents a relation that is not a function?

Artemon [7]

The second one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).

In every function, you must have a single "y" value for each "x" in the domain.

__________

In order to see it better, you can trace a vertical line onto that graph.

If that line and the graph intersects in more than one point, then that graph doesn't represent a funcion.

Look into the attached picture and see. That vertical red line and the graph intersects in two distinct points. Therefore, it can't represent a function.

Any doubt? Please, comment below.

I hope it helps. :-)
