Answer:
x = ±i(√6 / 2)
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
<u>Algebra II</u>
Imaginary root i
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
2x² + 3 = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 3 on both sides: 2x² = -3
- [Division Property of Equality] Divide 2 on both sides: x² = -3/2
- [Equality Property] Square root both sides: x = ±√(-3/2)
- Simplify: x = ±i(√6 / 2)
Answer:
add 12 +9 because i had that same answer on my quiz last week
Answer
i think this is what you mean
Step-by-step explanation:
x y
2 0
1 2
0 4
-1 6
-2 8
Answer:
Solution given:
y=25 [base side of isosceles triangle]
sin 45=opposite/hypotenuse
sin45=25/x
x=25/sin45
x=25√2
Estimate the total amount you should plan to spend on gasoline for the entire trip
<em>Total distance of the trip</em> = 1430 miles
<em>After 350 miles, refill tank</em> = $35
This means 350 miles cost $35
1430 miles cost $x
solve using ratio
350 : 35 = 1430 : x
350/35 = 1430 / x
10 = 1430/x
<em>cross product</em>
10x = 1430
<em>Divide both sides by 10</em>
x = 1430 / 10
x = $143
Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143
