Given A and B are vertical angles with m anglr A = 20x + 10 and m angle B =30x - 10 , what is X?
Answers
Answer: The answer is 2
Step-by-step explanation:
Given A and B are vertical angles with m ∠A = 20x + 10 and m ∠B =30x - 10, the value of x is 2
From the Vertical angle theorems, we have that
Two opposite vertical angles formed when two lines intersect each other are always equal to each other.
Now, from the question, we are given that A and B are vertical angles
That means
A = B
Also, from the question
measure of angle A = 20x + 10 and measure of angle B = 30x - 10
To determine the value of x, we will equate the two equations to each other
A = 20x + 10
B = 30x - 10
Since, A = B
∴ 20x + 10 = 30x - 10
To solve for x,
First, add 10 to both sides20x + 10 + 10 = 30x - 10 +10
We get
20x + 20 = 30x
Now, subtract 20x from both sides20x - 20x + 20 = 30x - 20x
20 = 10x
That is,
10x = 20
∴ x = 20 ÷ 10
x = 2
Hence, given A and B are vertical angles with m ∠A = 20x + 10 and m ∠B =30x - 10, the value of x is 2

Given f(x) = 70 + 11x, find x when f(x) =158
Answers
Answer:
[tex] \huge \boxed{x = 8}[/tex]
Step-by-step explanation:
f(x) = 70 + 11x
To find the value of x when f(x) =158 , equate f(x) to 158
We have
[tex]70 + 11x = 158 \\ 11x = 158 - 70 \\ 11x = 88[/tex]
Divide both sides by 11
[tex] \frac{11x}{11} = \frac{88}{11} \\ [/tex]
We have the final answer as
x = 8Hope this helps you

PLEASE HELP!! If f (x) = 4x^-2 + 1/4x^2 + 4, then f’(2) =
Answers
Work Shown:
f(x) = 4x^(-2) + (1/4)x^2 + 4
f ' (x) = 4*(-2)x^(-3) + (1/4)*2x .... power rule
f ' (x) = -8x^(-3) + (1/2)x
f ' (2) = -8(2)^(-3) + (1/2)*(2)
f ' (2) = 0
Finding the derivative, we have that f'(2) = 0, option D.
-----------------------------
The derivative of an exponent is:[tex](x^n)^{\prime} = nx^{n-1}[/tex]
Additionally, the sum of the derivatives is the derivative of the sum. The derivative of a constant is zero.-----------------------------
The function is:
[tex]f(x) = 4x^{-2} + \frac{x^2}{4} + 4[/tex]
The derivatives are:
[tex](4x^{-2})^{\prime} = -2 \times 4x^{-2 -1} = -8x^{-3}[/tex]
[tex](\frac{x^2}{4})^{\prime} = \frac{2x}{4}[/tex]
[tex](4)^{\prime} = 0[/tex]
Thus, the derivative of the function is:
[tex]f^{\prime}(x) = -8x^{-3} + \frac{2x}{4} = -\frac{8}{x^3} + \frac{2x}{4}[/tex]
At x = 2:
[tex]f^{\prime}(2) = -\frac{8}{2^3} + \frac{2(2)}{4} = -1 + 1 = 0[/tex]
Thus f'(2) = 0, option D.

Step-by-step explanation:
Sidney applied the steps to find the product of two numbers (3.1) and (-1.6),
Step 1,
(3.1)(-1.6) = (-1.6)(3.1)
Step 2,
(-1.6)(3.1) = (-1.6)(3 + 0.1)
Step 3,
(-1.6)(3 + 0.1) = -4.8 + (-0.16) [Distributive property]
Step 4,
-4.8 + (-0.16) = -4.96
