The quadratic equations are solved and answered below -
<h3>What is a equation?</h3>
An equation is a mathematical statement showing the equivalence of two mathematical expressions. Example -
3x + 5 = 8
Given is -
3x² - 7 = 31
2x² + 18 = 0
4x² - 26 = - 50
2x² + 36 = x²
We have -
3x² - 7 = 31
3x² = 38
x² = 38/3
x² = 12.67
x = ±3.56
2x² + 18 = 0
2x² = - 18
x² = -9
x = ±3i
4x² - 26 = - 50
4x² = - 24
x² = -6
x = ±√6i
2x² + 36 = x²
x² = - 36
x = ±√6 i
Therefore, the quadratic equations are solved above.

Answer:
55,7425
Step-by-step explanation:
Since there are 60 minutes in one degree and 3600 seconds in one degree, the formula is:
Decimal degrees = Degrees + (Minutes/60) + (Seconds/3600)
Here Degrees stay the same 55;
44' = 44/60 ≈ 0,733...
33" = 33/3600 ≈ 0,009166...
I've divided and added those three numbers by calculator in one operation and it shows exactly 55,7425. If you add them separately, you'll need to round the result.
Answer:
f(1) = - 2
Step-by-step explanation:
f(1)
Means find the value of y when x = 1
From the graph the point (1, - 2)
is the point where y is - 2 and x is 1
Thus
f(1) = - 2
Answer:
22 tickets
Step-by-step explanation:
I assume you're asking about question 2
To find a fraction of a whole number you divide by the bottom number and multiply by the top number. If 2/3 are kids tickets then 1/3 are adult tickets so you divide by 3 and multiply by 1
