I think the awkward science is quite amusing to me
A line. It goes in both directions forever
Answer:
x = (5 + i sqrt(15))/4 or x = (5 - i sqrt(15))/4
Step-by-step explanation:
Solve for x:
2 x^2 - 5 x + 5 = 0
Hint: | Using the quadratic formula, solve for x.
x = (5 ± sqrt((-5)^2 - 4×2×5))/(2×2) = (5 ± sqrt(25 - 40))/4 = (5 ± sqrt(-15))/4:
x = (5 + sqrt(-15))/4 or x = (5 - sqrt(-15))/4
Hint: | Express sqrt(-15) in terms of i.
sqrt(-15) = sqrt(-1) sqrt(15) = i sqrt(15):
Answer: x = (5 + i sqrt(15))/4 or x = (5 - i sqrt(15))/4
Answer:
(-3,5)
Step-by-step explanation:
If you start at the origin (0), going up 5 spaces will leave you at 5 for your y plot. Then, 3 spaces <em>left</em> leaves you at -3 for your x. However, when writing down plots, you write x before y. So, you are left with (-3,5) as your coordinate plot for the final answer.
Divide 3 by 3/4 and you will get your answer. you can also multiply 3×4/3. it's the same thing
