Answer:

option D is correct

The value of x is 2

Step-by-step explanation:

Given the function: f(x) = 2(x+10)

if f(x) = 24 then solve for x;

Distributive property of multiplication states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately.

i,e  a\cdot(b+c) = a\cdot b+ a\cdot c

f(x) = 2(x+10)

Applying distributive property we have;

f(x) = 2\cdot x + 2\cdot 10 = 2x+20

Now, substitute the value of f(x) = 24 to solve for x;

24 = 2x+20

Subtraction property of equality states that you subtract the same number to both sides of an equation.

Subtract 20 to both sides of an equation, we get

24-20 = 2x+20-20

Simplify:

4 = 2x

Division property of equality states that you divide the same number to both sides of an equation.

Divide both sides by 2 we get

\frac{4}{2} = \frac{2x}{2}

Simplify:

x =2

therefore, the value of x is 2.

Given the function of f(x) = 2(x+10), find x if f(x)=24 will be 2. The correct answer will be D. 

The steps to get the answer are;
<span>2(x+10)=24 2x +20=24 -20 -20 2x=4/2 x=2</span>

How do I construct angle XYZ with a measure of 2 times the measure of angle ABC
Serjik [45]
I can’t understand why everyone complicates this question. It can be easily solved by similar triangles.


In this png, we have something to make sure.

∠B=∠DAB

(Yes, dab)

This also means AD=BD

.

This is our basic construction of D, which is going to help us.

∠ADC=∠DAB+∠B=2∠B=∠CAB

These are based on the fact that ∠A=2×∠B

Actually these conditions suffice. Because I am just proving that △ACD∼△BCA

Similarity makes us realize the following:

ACBC=ADAB

and

ACBC=CDAC

So

and

So

Express 7. 66 repeating as a ratio of two integers.
OverLord2011 [107]
Method A: 7.6666.... = 7 + 0.6666... = 7 + 2/3 = 21/3 + 2/3 = 23/3

Method B: 10(7.666...) - 1(7.666...) = 76.666... - 7.666... = 69.000...
(10 - 1)(7.666...) = 69
7.666... = 69/9 = 23/3
