2x^2 + 8x = 0
This has TWO answers!
Thank you so much!!!
y =2/x^(2) + 3
One possible answer is:
f(x) = (2/x) + 3 and g(x) = x².
Explanation:
We are to write this equation as y = f(g(x)). This means we want it to be a composite of functions; in f(x), we take the value of g(x) and use in place of x.
If we let g(x) = x², this means everywhere we see an x in f(x), we will replace it with x². To make our equation y = 2/x² + 3, working backward we would substitute x for x²; this would give us f(x) = 2/x + 3.
Answer:
(-2x ÷ 5) - (9/5 ÷ 5) = -2/5 * x - 9/25
Step-by-step explanation:
To solve the expression (2x - 2 1/5 - -4) ÷ -5, we need to follow the order of operations, also known as PEMDAS.
1. First, simplify the expression inside the parentheses (-2 1/5 - -4).
To subtract a negative number, we can change it to addition. So, (-2 1/5 - -4) becomes (-2 1/5 + 4).
Next, let's convert the mixed number -2 1/5 to an improper fraction.
-2 1/5 = -11/5
Now we can add the fractions: -11/5 + 4.
To add these fractions, we need a common denominator. The least common denominator for 5 and 1 is 5.
-11/5 + 4/1 = -11/5 + 20/5 = 9/5
Therefore, (-2 1/5 - -4) simplifies to 9/5.
2. Now, let's substitute the simplified expression back into the original expression: (2x + 9/5).
3. Finally, divide the expression by -5: (2x + 9/5) ÷ -5.
To divide by a negative number, we can multiply the expression by -1 and then divide by 5.
(2x + 9/5) ÷ -5 = (-1)(2x + 9/5) ÷ 5
Applying the distributive property, we get:
(-1)(2x + 9/5) ÷ 5 = (-2x - 9/5) ÷ 5
To divide by 5, we can multiply each term by 1/5:
(-2x - 9/5) ÷ 5 = (-2x ÷ 5) - (9/5 ÷ 5)
Simplifying further:
-2x ÷ 5 = -2/5 * x
9/5 ÷ 5 = 9/25
Therefore, the final answer is:
(-2x ÷ 5) - (9/5 ÷ 5) = -2/5 * x - 9/25
Please note that this is the simplified form of the expression, assuming that no specific value for x is given.
The value of the variable 'x' using the cosine formula will be 9.4 units.
It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.
The value of 'x' is given by the cosine of the angle ∠VWU. And the cosine of an angle is the ratio of the base and hypotenuse of the right-angle triangle. Then we have
cos 32° = 8 / x
x = 9.4
The value of the variable 'x' using the cosine formula will be 9.4 units.

Answer:
9.4
Step-by-step explanation:
cos 32° = 8/x
x = 8/ cos 32°
= 8/ 0.8480
= 9.4
B) $780
C) $928
D) $2,412.80
Answer:
The correct answer is D. $2412.8
Step-by-step explanation:
Sum of all liabilities Barry bought = 100 + 300 + 50 = $450
But $500 is deductible so there will be no charge on the liabilities.
Now, Sum of base premiums = 450 + 245 + 148 + 85 = $928
Also, the rating factor = 2.60
∴ Total base premium = (Sum of base premium) × Rating factor
= 928 × 2.60 = $2412.8
Therefore, the correct answer is D. $2412.8
