-X² + 5x - 6 = 2
Using the quadratic formula

Answers

Answer 1

[tex]-x^2+5x-6=2\\-x^2+5x-6-2=0\\-x^2+5x-8=0\\[/tex]

↝ Form into [tex]ax^2+bx+c = 0[/tex] where a > 0 (Optional)

[tex]x^2-5x+8=0[/tex] ↝ Multiply -1 for both sides.

↝ Then proceed with the Quadratic Formula.

x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula

[tex]x=\frac{-(-5)+-\sqrt{(-5)^2-4(1)(8)}}{2(1)}\\x=\frac{5+-\sqrt{25-32}}{2}\\[/tex]

↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.

Solution with Real Numbers  System ↝  There are no real solutions.

Solution with Complex Number System

[tex]x=\frac{5+-\sqrt{25-32}}{2}\\x=\frac{5+-\sqrt{-7}}{2}\\x=\frac{5+-\sqrt{7}i }{2}[/tex]

Therefore, the answer for Complex Number System is (5±√7i)/2

identify the equation of the line having a slope of -3 and a y- intercept of 7

A y + -3x +12
b y = 3x - 7
c y = 3 + 7
d y = -3x + 7

Answers

Answer:

D.

Step-by-step explanation:

We can use the slope-intercept form:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

We know that the slope is -3.

And the y-intercept is 7.

Hence, we will substitute -3 for m and 7 for b. This yields:

[tex]y=-3x+7[/tex]

Therefore, our answer is D.

What is the value of x in the equation 4(2x − 1) = 2x + 35?

Answers

Answer:

x = 6.5 or 13/2

Step-by-step explanation:

4(2x − 1) = 2x + 35

distribute the 4 to 2x - 1

8x - 4 = 2x + 35

subtract 2x

6x - 4 = 35

add 4

6x = 39

divide by 6

x = 6.5 or 13/2

Suppose there are three types of consumers who attend concerts at your university’s performing arts center: students, staff, and faculty. Each of these groups has a different willingness to pay for tickets; within each group, willingness to pay is identical. There is a fixed cost of $1,000 to attend the concert, but there are essentially no variable costs.

For each concert:

• There are 150 students willing to pay $20.

• There are 200 staff members willing to pay $35.

• There are 120 faculty members willing to pay $50.

Answers

Answer: i. There are 140 students willing to pay $20.

ii. There are 200 staff members willing to pay $35.

iii. There are 100 faculty members willing to pay $50.

Step-by-step explanation: Suppose there are three types of consumers who attend concerts at Marshall university's performing arts center: students, staff, and faculty. Each of these groups has a different willingness to pay for tickets; within each group, willingness to pay is identical. There is a fixed cost of $1,000 to put on a concert, but there are essentially no variable costs.

For each concert:

A) If the performing arts center can charge only one price, what price should it charge? What are profits at this price? B) If the performing arts center can price discriminate and charge two prices, one for students and another for faculty/staff, what are its profits?

C) If the performing arts center can perfectly price discriminate and charge students, staff, and faculty three separate prices, what are its profits?

No explanation required

Answers

Answer:  Yes it is a function.

Reason:

There are no repeated x values, so each x input leads to exactly one y output. That's why we have a function.

If we had something like (1,18) and (1,12), then the input x = 1 leading to simultaneous outputs y = 18 and y = 12 would mean we wouldn't have a function.
