Answer:
Your answer should be 15.905625, if it's not 15 percent off per pound.
Step-by-step explanation:
Multiply 4.99 x 3.75 then multiply that answer (18.7125) by .15
That will leave you with 2.806875, which then you subtract that from 18.7125
That will give you your answer, 15.90...

Answer:
The equation has two solutions for x:
<u>x₁ = (8 + 10i)/2</u>
<u>x₂ = (8 - 10i)/2</u>
Step-by-step explanation:
Let's use the quadratic formula for solving for x in the equation:
X^2 - 8X + 41= 0
x² - 8x + 41 = 0
Let's recall that the quadratic formula is:
x = -b +/- (√b² - 4ac)/2a
Replacing with the real values, we have:
x = 8 +/- (√-8² - 4 * 1 * 41)/2 * 1
x = 8 +/- (√64 - 164)/2
x = 8 +/- (√-100)/2
x = 8 +/- (√-1 *100)/2
Let's recall that √-1 = i
x = 8 +/- 10i/2
<u>x₁ = (8 + 10i)/2</u>
<u>x₂ = (8 - 10i)/2</u>
-2(4x-1)=5+7
(4x-1)=12/-2
4x=-6+1
x=-5/4
