Mrs. Solar modeled Contractor 2’s fees with the formula y = 150 + 55x. Mrs. Solar compared Contractor 2’s fee to Contractor 1’s fee.

(a) What does the difference between 50 and 55 mean in the real-world context?
(b) What does the difference between 200 and 150 mean in the real-world context?

Answers

Answer 1
Answer: I'm guessing that you forgot to put contractor 1's fees
judging from the question, I would assume that his fees are y=200+50x
I will assume that y=fee and x=number of hours (or units of time)

so
a. difference between 55 and 50, that is 5 so #2's fee is 5$ more for every hour he works
b. difference between200 and 150 means that contractor 1 gets 50 more initally than contractor 2

These students are:

Maria

Zack

Bo


The correct answer is C.

Answer:

Option C - (Maria , Jack and Bo)

Step-by-step explanation:

Given : The Venn diagram shows the pizza topping preferences for 9 students.

To find : What are the elements are in A and B?

Solution :

Let event A =  student like pepperoni

Let event B = students like olives  

We have to find the elements in A and B

A and B means the intersection of event A and event B.  

From the Venn Diagram, the number of students who likes Pepperoni and Olives are the students in the intersection of the two circles inside the rectangle.

The students in the intersection of A and B are Maria , Jack and Bo.

Therefore, Option C is correct.

How do I solve system of equations by substitution
y=-2x+2
y=7x+11

Answers

Answer:

(-1, 4)

Step-by-step explanation:

We are told that:

y = -2x + 2 and

y = 7x + 11.

We can eliminate "y" by setting these two equations = to each other:

-2x + 2 = 7x + 11.

We need to solve this equation for x.

Adding 2x to both sides, we get 2 = 9x + 11.

Subtracting 11 from both sides results in -9 = 9x.  Thus, x = -1.

Find y by subbing -1 for x in either of the given equations.

If we use the 2nd equation, then y = 7(-1) + 11, or y = 11-7, or y = 4.

The solution of this system of linear equations is (-1, 4)

Answer: 3,000 milliliters
3000 milli liters is equal to 3L

Solve for X and Y 3x+(2 x-y)i = 6-3i

Answers

Answer:

x = 2 and y = 7

Step-by-step explanation:

\text{Two complex numbers are equal when they have equal real parts}\n\text{ and equal imaginary parts}\n\na+bi=c+di\iff a=c\ and\ b=d

3x+(2x-y)i=6-3i\iff3x=6\ \wedge\ 2x-y=-3\n\n3x=6\qquad\text{divide both sides by 3}\n\n\boxed{x=2}\n\n\text{Put the value of x to the second equation:}\n\n2(2)-y=-3\n\n4-y=-3\qquad\text{subtract 4 from both sides}\n\n-y=-7\qquad\text{change the signs}\n\n\boxed{y=7}
