Answer:

One possible solution is 5 + i√3.

(there are 2 solutions 5 + i√3 and 5 - i√3).

Step-by-step explanation:

(x - 5)^2 + 5 = 2

(x - 5)^2  = -3

Take square roots of both sides:

x - 5 = √-3

x - 5 = i√3

x = 5 ±  i√3.

The solutions are both complex numbers.

Write the slope-intercept form of the equation of the line that is perpendicular to AB and passes through Point X. Show all work
aleksandr82 [10.1K]

Answer:

Equation of line is y=(12/5)x+2

Step-by-step explanation:

The slope of line AB is -5/12. The line passing X is perpendicular to line AB and hence have a slope of 12/5. The slope intercept form is given by y=mx+c.

Now, point X satisfies the equation. Plugging in the slope of the line we end up with

y=(12/5)*x+c, now to find c

-10=(12/5)*(-5)+c, c=2

Equation of line is y=(12/5)x+2

Zepler [3.9K]

Answer:

  • D.  l = 3  ||  4 < c < y   ||  8l + 7.5c ≥ 70

Step-by-step explanation:

<h3>Work at library</h3>
  • Time  = 3 hours ⇒ l = 3
  • Payment = $8 per hour
  • Total payment = 8l
<h3>Work at coffee shop</h3>
  • Time = between 4 and 7 hours ⇒ 4 < c < 7
  • Payment = $7.5 per hour
  • Total payment = 7.5c

Target income = at least $70 daily  

<u>So the system as per above parameters:</u>

  • l = 3
  • 4 < c < y
  • 8l + 7.5c ≥ 70

Correct option is D
