Answer: x = the quantity of 5 plus or minus the square root of 29 all over 2
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 5x - 1 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the given quadratic equation,
a = 1
b = - 5
c = - 1
Therefore,
x = [- - 5 ± √(- 5² - 4 × 1 × - 1)]/2 × 1
x = [5 ± √(25- - 4)]/2
x = [5 ± √29]/ 2
x = ( 5 + √29)/- 2 or x = (5 - √29)/2
I can't tell you the answers cause that's cheating but I can explain how to do it.
Let's use number 1 for an example. It says 1/2 x 2 1/3. First what we want to do is turn all mixed numbers into fractions. So how to do that is take the whole number, in this case 2, and multiply it by the denominator, which in this case is 3. The answer you will get is 6. Then you have to add the numerator onto that, which means 6 + 1 = 7. So now the equation is 1/2 + 7/3. Now you can just multiply both numerators and denominators, so 1 x 7 and 2 x 3, and you will get 7/6, which can be converted to 1 1/6. Apply this method to any of those problems.
Hope this helped!

Since the line starts with a closed dot, it resembles ≥ and ≤. We can write an inequality to represent it:
j ≤ -5
This means that all real numbers are solutions to the inequality except the numbers greater than -5.
Since we are using the closed dot, -5 is included as one of the solutions. It also satisfies the inequality we wrote above.
5 ≤ 5
Therefore, the answer is [ True ]
Best of Luck!
